Building libEGL and libGLESv2 as static libraries on Windows

[Tibor den Ouden]

If I change 'angle_gl_library_type%' to 'static_library'

in angle.gyp (line 21) and run glient runhooks,

I can build static libs for libEGL and libGLESv2

Only when I start linking them to an application (hello_triangle for instance)

I get unresolved symbols.

This is due to the exported functions still containing the dll interface calling conventions.

By changing the following lines in : angle/include/export.h :

#if defined(_WIN32)

#   if defined(LIBGLESV2_IMPLEMENTATION) || defined(LIBANGLE_IMPLEMENTATION)

#       define ANGLE_EXPORT __declspec(dllexport)

#   else

#       define ANGLE_EXPORT __declspec(dllimport)

#   endif

#elif defined(__GNUC__)

to :

#if defined(_WIN32)

#   if defined(LIBGLESV2_IMPLEMENTATION) || defined(LIBANGLE_IMPLEMENTATION)

#       define ANGLE_EXPORT 

#   else

#       define ANGLE_EXPORT 

#   endif

#elif defined(__GNUC__)

And in : angle/include/KHR/khrplatform.h :

#if defined(_WIN32) && !defined(__SCITECH_SNAP__)

#   define KHRONOS_APICALL __declspec(dllimport)

#elif defined (__SYMBIAN32__)

to :

#if defined(_WIN32) && !defined(__SCITECH_SNAP__)

#   define KHRONOS_APICALL 

#elif defined (__SYMBIAN32__)

that is solved.

For applications for which the project files are not generated from .gyp files

you have to add d3d9.lib to the Linker Input as Additional Dependencies for release builds.

For debug builds you have to add d3d9.lib and dxguid.lib.

Is there a 'default' way to change the dll interface calling conventions for static libs ?

Otherwise, if building libEGL and libGLESv2 as static libraries on Windows is still supported,

I can provide a changelist to fix the calling conventions for ANGLE_EXPORT and KHRONOS_APICALL.

I think a new preprocessor define is needed :

ANGLE_STATIC_LIBS, ANGLE_BUILD_STATIC_LIBS ?

[Jamie Madill]

Hey Tibor,

Can you open an issue on the issue tracker for this?

I agree that we'll likely need a new define, and that the new define has the effect of turning off the dllexoprt/dllimport.

All you need do is -DGL_APICALL -DEGLAPI on the compile command when compiling the library. That is because the gl*platform.h files contain

#ifndef GL_APICALL

#define GL_APICALL  KHRONOS_APICALL

#endif

and eglplatform.h contains

#ifndef EGLAPI

#define EGLAPI KHRONOS_APICALL

#endif

Users of a static library will also need to add these defines to their compile commands.

These are the same macros you need to define differently when building a shared library (at least on Windows you have to change import to export).

I also have a requirement to build static libs on Windows.  Is there an "out of the box" way of doing this that doesn't require any source changes?  If yes, what are the steps?

thx

It appears that static libraries are now created by default by the windows build.  I'm having trouble consuming them, though.

I've had to define:

#define GL_GLEXT_PROTOTYPES

#define EGL_EGL_PROTOTYPES

in order to make things compile but when i attempt to call eg eglinitialize

if (eglInitialize(mEglDisplay, NULL, NULL) == EGL_FALSE)

I get a linker error

1>AngleRenderer.lib(OpenGLES.obj) : error LNK2019: unresolved external symbol __imp_eglInitialize referenced in function "private: void __cdecl OpenGLES::Initialize(void)" (?Initialize@OpenGLES@@AEAAXXZ)

I've looked at the static lib in dump bin and it appears to be exporting eglInitialize, not __imp_eglInitialize.. 

I too need an out of the box way to do this as I'm attempting to link angle in to the flutter engine and hence it needs to be vanilla angle referenced by GN.

[Geoff Lang]

I think we currently only test with the static libraries on Android (in Chrome) and it's done by loading all entry points out of eglGetProcAddress so it looks like something broke on Windows.  Can you file a bug about it? Any more investigations would help us fix it faster.

I think you are using a very old version of the OpenGL ES header or the wrong header (i.e. an Open GL header). Current headers #define GL_GLES_PROTOTYPES 1 and do not use GL_GLEXT_PROTOTYPES and there is no #ifdef on EGL_EGL_PROTOTYPES in the current egl.h.

And this part is not an ANGLE issue. A static library should not have symbols defined with __imp. Your application has been compiled to link with a dynamic library.  One way to make it compile for a static library is what Pada wrote in that old message you quoted. The official way is

-DKHRONOS_STATIC

which will result in KHRONOS_APICALL being defined as an empty string for both OpenGL ES and EGL instead of as __dllimport.

It's possible I broke the standard Khronos way with one of my redesigns. It did involve tweaking the headers to be non-standard for some older headers like egl.h.

I don’t think you have any problem with the ANGLE static library build for Windows. The only issue is compiling the app to link with a static library.  One or both of -DGL_APICALL -DEGLAPI or -DKHRONOS_STATIC needs to work.

Which version of egl.h are you referring to? Old versions of egl.h defaulted to static, i.e #define EGLAPI extern. Newer ones use eglplatform.h which in turn uses KHR/khrplatform.h. 

No Khronos egl.h has ever used an EGL_EGL_PROTOTYPES macro. Every version has the prototypes defined unconditionally.

I made custom headers for EGL.h and GLES 1.x. I needed some features (function pointer types, prototype guards) that weren't enabled for the default headers. I used the Khronos generators. More detail (but only barely) here:

Is the guard defined by default? I couldn’t tell from the brief detail at the link. It should be for compatibility with real egl.h and with the OpenGL ES header.

I just updated the bug with a reduced repro for my scenario.

I’m not an ANGLE project member so I can’t add any comments to the bug so I’ll give feedback here.

I repeat. The link error is NOT an ANGLE bug. Most users on Windows use dlls so the header defaults are set so that applications will be compiled to link with a dll. That’s the __imp you are seeing. You have to define the macros previously mentioned in order for your app to be compiled to link with a static library.

Re the issue with EGL_EGL_PROTOTYPES. It is the intention in all Khronos headers that use such a construct that you should #define FOO_FOO_PROTOTYPES=1. This is so those using runtime loading of function pointers can turn off the prototypes with -DFOO_FOO_PROTOTYPES=0. Some build systems don’t support undef very well.

ANGLE needs to add

#ifndef EGL_EGL_PROTOTYPES

#define EGL_EGL_PROTOTYPES 1

#endif

to its header to so that the prototypes are there by default. That will make their header compatible with the standard egl.h and with the usage of the OpenGL ES headers. This is the only ANGLE bug that I see.

I do not know why you think you need GL_GLEXT_PROTOTYPES. The ANGLE GLES/gl3.h, which looks like the Khronos standard header, like that header uses GL_GLES_PROTOTYPES and defines it as 1 with a code block like the above. GL_GLEXT_PROTOTYPES is used only in gl*ext.h. I don’t know of any implementations that make extension functions available for link time resolution so there isn’t much need to ever define it.

Thanks Mark, following up on this older post. Filed http://anglebug.com/3706 and working on it now.

What’s the current status of this? Does the default build create static libraries or do I need to set some arguments? Thanks

[Oliver Larkin]

I followed the DevSetup.md instructions. I saw some .libs built in \obj which look like they should work, but when i try and link I get an error 

C:\Users\oli\Dev\angle\out\Debug\obj\libGLESv2_static.lib : fatal error LNK1127: library is corrupt

I had to define the following as discussed above

GL_APICALL=;EGLAPI=

anyone know what the issue might be there?

thanks

[Geoff Lang]

Corrupt lib could be a bunch of things.  Is there a 32/64-bit conflict?  Also try wiping the out directory and rebuild.

building via the visual studio solution gave me 2 much more reasonable size .lib files with don't give that error at link stage. Unfortunately now i get a tonne of linker errors.

Are there any instructions for static linking somewhere?

thanks

To preface this, the _static.lib stuff isn't used very often, so we don't have too much experience debugging issues with it.

I wonder if there are more libs you have to link to get this working.  I suspect there is a libANGLE.lib and possibly others (common.lib?) that you can try linking too.  The missing symbols I see (ScopedPerfEventHelper and gl::FromGLenum) would be part of a common.lib.

[Nespre t]

This feature could be a great addition, especially on UWP.

Right now, there are a lot of missing symbols.

[Oliver Larkin]

It would be great if the gn/ninja scripts could make working static libs out of the box, still haven’t managed to make that work

I vaguely remember seeing this before.

Ideas:

 - You may need to link more of the ANGLE libs, libANGLE.lib and others

 - It looks like a name mangling issue.  You may have to define GL_APICALL and GL_APIENTRY like we do in our build.gn files:  https://source.chromium.org/chromium/chromium/src/+/master:third_party/angle/BUILD.gn;l=826

Ah, I see.  libANGLE is a source_set in gn so it may get folded into some other static library.  There must be some .lib in there with these symbols.

I thought that too.

In a powershell prompt, I tried the command « ls -include ('*.lib','*.obj') -r | sls -SimpleMatch 'ANGLEGetDisplayPlatform' | Select -unique path » and I got :

[Geoff Lang]

From the log you posted, all the missing functions are ES1 functions.  You could try not linking libGLESv1_CM_static and make sure you're not referencing any of those entry points.  I'm not sure why those specifically would be missing from our context class.

I tested what you've recommended.

It doesn't work either.

Currently, I'm using those headers:

//  Enable function definitions in the GL headers below
#  define GL_GLEXT_PROTOTYPES
//  OpenGL ES includes
#  include <GLES2/gl2.h>
#  include <GLES2/gl2ext.h>
//  EGL includes
#  include <EGL/egl.h>
#  include <EGL/eglext.h>
#  include <EGL/eglplatform.h>
//  ANGLE include for Windows Store
#  include <angle_windowsstore.h>

With libGLESv1_CM_static or without doesn't change much.

I vaguely remember seeing this before.

Ideas:

 - You may need to link more of the ANGLE libs, libANGLE.lib and others

 - It looks like a name mangling issue.  You may have to define GL_APICALL and GL_APIENTRY like we do in our build.gn files:  https://source.chromium.org/chromium/chromium/src/+/master:third_party/angle/BUILD.gn;l=826  

Yes. These errors are because the application has been compiled to link with a Windows shared library - the default behavior of the header files. The clue is the __imp__. To build it for linking to a static library you need to define GL_APICALL & GL_APIENTRY appropriately.

Hi, Thanks for your help.

I tried to define GL_APICALL and GL_APIENTRY. But I still get some weird link issues:

[Nespre t]

After some digging, I encounter an issue that could be related to the UWP build.

The static libraries must be built with -ZW in order to be UWP «compliant».

Is there a way to check that somewhere in the GN files ?

[Nespre t]

In my case, trying to work with cppwinrt and ANGLE as static library in the same time is probably the issue.

[Matt Esch]

After spending some time working on this there is clearly an issue with the generated ninja files for libGLESv2_static.ninja but I'm not exactly sure how to fix this in the related BUILD.gn

If you make a comparison between the libGLESv2.ninja and libGLESv2_static.ninja you can see that the missing files (and related linker errors) come from the fact that the object files from libANGLE_base are missing and there is no supplementary library that should be included. You would however expect libGLESv2 and libGLESv2_static to be equivalent.

I was able to manually edit the libGLESv2_static.ninja to include the missing files and static compilation worked, as long as the required libraries were included and the aforementioned definitions were set.

How I generated the solution:

gn gen -v out/Release --sln=angle-release --ide=vs2019 --args="target_cpu=\"x86\" is_clang=false is_debug=false angle_enable_metal=false angle_enable_swiftshader=false angle_enable_vulkan=false"

Note that I had some issues with a badly generated solution that included the linker option "/llvmlibthin" which is not compatible with the msvc linker (I used is_clang=false to guard against this).

From libGLESv2_static.lib (notice that there is hardly anything included):

#define GL_APICALL

Compulsory libs I had to link in my use case (as the static library does not link the libs). You can also borrow the ldflags and libs from libGLESv2.ninja when building you own project because this is a bit more sophisticated (delay load d3d9.lib etc)

If I change 'angle_gl_library_type%' to 'static_library'

in angle.gyp (line 21) and run glient runhooks,

I can build static libs for libEGL and libGLESv2

Only when I start linking them to an application (hello_triangle for instance)

I get unresolved symbols.

This is due to the exported functions still containing the dll interface calling conventions.

By changing the following lines in : angle/include/export.h :

#if defined(_WIN32)

#   if defined(LIBGLESV2_IMPLEMENTATION) || defined(LIBANGLE_IMPLEMENTATION)

#       define ANGLE_EXPORT __declspec(dllexport)

#   else

#       define ANGLE_EXPORT __declspec(dllimport)

#   endif

#elif defined(__GNUC__)

to :

#if defined(_WIN32)

#   if defined(LIBGLESV2_IMPLEMENTATION) || defined(LIBANGLE_IMPLEMENTATION)

#       define ANGLE_EXPORT 

#   else

#       define ANGLE_EXPORT 

#   endif

#elif defined(__GNUC__)

And in : angle/include/KHR/khrplatform.h :

#if defined(_WIN32) && !defined(__SCITECH_SNAP__)

#   define KHRONOS_APICALL __declspec(dllimport)

#elif defined (__SYMBIAN32__)

to :

#if defined(_WIN32) && !defined(__SCITECH_SNAP__)

#   define KHRONOS_APICALL 

#elif defined (__SYMBIAN32__)

that is solved.

For applications for which the project files are not generated from .gyp files

you have to add d3d9.lib to the Linker Input as Additional Dependencies for release builds.

For debug builds you have to add d3d9.lib and dxguid.lib.

Is there a 'default' way to change the dll interface calling conventions for static libs ?

Otherwise, if building libEGL and libGLESv2 as static libraries on Windows is still supported,

I can provide a changelist to fix the calling conventions for ANGLE_EXPORT and KHRONOS_APICALL.

I think a new preprocessor define is needed :

ANGLE_STATIC_LIBS, ANGLE_BUILD_STATIC_LIBS ?

My understanding is that public deps are propagated to shared libraries and not static objects, so the public_deps from libAngle need to be included manually.

[Jamie Madill]

Matt, static link requires that you manually link every dependent static library of libGLESv2 into your target. Not just libGLESv2_static, everything that libGLESv2 depends on. I suspect that's what is tripping you up.

Matt Esch, thanks for your help, however your patch in BUILD.gn didn't help for me.
Did you manage to get a static build working on microsoft windows ?

[Matt Esch]

I think my editing must not have worked as I expected, it's hard to keep track with manual edits. The technically correct answer has already been provided to building on windows - you do need to compile and statically link all the different components, however they don't all have static targets, I modified the target manually to get compiled static binaries, someone needs to figure out how to add static libraries for the missing components.

I have an example of the x86 binary:  https://github.com/Matt-Esch/unigl/tree/master/bin/windows/x86

Is there a way to get this working nowadays ?

I get a corrupted static lib file when I try to compile libGLESv2_static or libEGL_static

No problem so far on the dll version

[Jean Valjean]

So finally, the solutions lies in the « angle_white_box_tests » source code

Fine for me, I will dig into that direction.

Have a nice day.

I tried to follow the discussion but failed to understand if this problem has a solution or in the process of being addressed. Can anyone elaborate on the status of this issue? I'd really appreciate it.

It seems this is still an issue one Windows. The logical solution since these static.lib files are in the obj folder, there should be another one in there with the bulk of the ANGLE internals that are missing. From what's been said here it seems like a libangle_static.lib should be amongst them at a minimum. The GN project could just build it alongside the dll.lib one.

[I've been trying to understand the structure of the project without anything to go on and this seemed like the case, but I thought maybe it was mixing shared and static (i.e. the static.lib files served some technial purpose) because zlib.dll.lib is linked into the static.lib files, so I just actually built something and then I began understand what this thread was about.]

Sorry, is anybody home at angleproject? Left to my own devices I noticed a "is_component_build = false" args.gn argument that can put GN into static library mode. This gets a lot closer, however the libANGLE_base.ninja file that seems to include many of the missing functionality doesn't seem to output a LIB file. Instead it seems to just make "stamp" files as its target. Being unfamiliar with GN I'm out of my depth, but I don't have much choice but to carry on. I think that probably the build files need amendment. I've attached the libANGLE_base.ninja output because it takes a bit of work to build ANGLE in this mode. P.S. I hope one of the project members will open up to us on the outside soon, -Michael.

To try to end this thread... I've posted here (https://groups.google.com/g/angleproject/c/f7i0kucc5xM/m/ANzo95TmBwAJ) very clean/easy code for adding the missing static target to the root BUILD.gn file. Hopefully something like this will get added to ANGLE before too long so you don't have to hack it!!
