Building skia under windows7 with VS2015 Problems & Questions

[Wanderer]

Hello

I am on win7 64bit and want use skia for my c++ application. I am beginer and git and depot_tools are new for me. I watching some tutorials for git, but still I have problems to get sln from depot_tools.

Is build instruction for how to build skia completed, or not? I follow all instruction but I was forced my own searching and by trail and error with install depot tools and what is going wrong. For example before run gclient I need install some git inside depot_tools folder, then runing gclient works ok.

bin/gn gen out/Static --args='is_official_build=true'

doesn't work until I go inside bin folder and run this code:

 gn gen out/Static --args="s_official_build=true"

code:

ninja -C out/Static

do something, but I get this:

ninja: Entering directory `out/Static'

ninja: fatal: ReadFile: PopisovaŔ nie je platnř.

I tried instruction for windows, but without help

python infra/bots/assets/win_toolchain/download.py -t C:/toolchain

I got error that I am not loged, and I need run cipd.bat, after run it show me some very long url and ask for activation code, but url doesn't work. (404 error page)

code:

 python gn/gn_meta_sln.py

give me this error:

ERROR: At least one GN directory must have been built with --ide=vs

and I have no clue what to do.
there are not lots of instruction inside how to build skia. They expected there are users with knowledge of depot_tools.

Is there way get skia without depot_tools? Like simple sln project or compiled dll files? Or are there more detailed instruction step by step how to prepare and build skia for windows 7 ? (with error solutions, if any appear)

I lost several days with searching and learning, but without any solutions, and I try it with this way. Thanks.

Which shell are you using?  Bash?  Cmd?  Powershell?  Our documentation assumes a posix-sh-like shell.

So, for instance, in Cmd.exe, you would do this:

    bin\gn.exe gen out\Static "--args=is_official_build=true"

instead of

    bin/gn.exe gen out/Static '--args=is_official_build=true'

in bash.

I use cmd from git (git-cmd.exe)

I have had recent success using the cmd shell with admin privileges to install depot_tools. Once installed, I switch to git-bash for day to day work, although the cmd shell still works fine. I did not need to install git inside a depot_tools instruction or otherwise stray from the depot_tools installation steps. I am on Windows 7 64-bit.

I recommend starting over by deleting depot_tools and reinstalling from the steps on https://www.chromium.org/developers/how-tos/install-depot-tools using cmd with admin privileges.

Good luck!

You probably also have to set the `windk` variable in your `args.gn` file.  For me it looks like this:

    windk = "C:/dev/toolchain/depot_tools/win_toolchain/vs_files/d3cb0e37bdd120ad0ac4650b674b09e81be45616"

Since I installed my toolchain in "C:\dev\toolchain".

If you installed Visual Studio in the normal location you don't have to change the default windk,

  "C:/Program Files (x86)/Microsoft Visual Studio 14.0".

Thanks for tip. I start with new depot_tools instalation, run cmd with admin privileges and it start without problem until this error:

I have not seen this error.

You may want to check out this Microsoft article:

https://answers.microsoft.com/en-us/windows/forum/windows_7-files/system-error-183-cannot-create-file-when-that-file/e3970f63-d153-455a-90ad-f0929a70ec12

Also, you may wish to take your question to chromium since depot_tools isn't maintained by skia.

Check https://groups.google.com/a/chromium.org/forum/#!forum/chromium-dev to see if someone else is having your problem installing depot_tools.

Check crbug.com for an existing similar bug; if there isn't one, file a new one.

I think, instalation depot_tools is resolved, and trying build skia. As I wrote before, I got this messages when I run

Then I remember that I have VS installed on D:Programi\Visual Studio 2015\

I looked on the out\Static directory and discover that ninja files have bad path for visual studio. I tried change this manulay for toolchain.ninja file and try run ninja -C out/Static

It looks like, it compile 3 files and 4 it stopped because there are more ninja files with bad VS2015 path. How can I change the path for VS2015 in ninja without manulay rewrite all path inside ninja files?

Try overriding windk in your GN args?  The default is 

  windk = "C:/Program Files (x86)/Microsoft Visual Studio 14.0"

[Wanderer]

Thank, but for future will be good if you write more, because I allways must find where and how to I rewrite it. I found only: I go in to BUILD.gn file and rewrite it. And don't know if it is right way.

After this, when I build with ninja i got this:

I have a custom CMakeLists.txt to build Skia, optionally with all its dependencies. The Skia CMakeLists is located here: https://github.com/skui-org/skia/blob/m58/CMakeLists.txt
If you want to also build its (minimal) dependencies, check out the proper repo of the mother project: https://github.com/skui-org/3rdparty?files=1

I use it successfully to build Skia on Linux with GCC/Clang/ICC and on Windows with Visual Studio 2015 and 2017.

[Wanderer]

Thanks, but unfornately it is not working for me. When I generate, CMake throw me some error with missing libraries.

On other side I finnaly build skia and resolve problems. But I got another problems with building simple program with skia library in this topic https://groups.google.com/forum/#!topic/skia-discuss/0L-wmHSbc2E

rubenvb - you are my hero.  I was able to use your cmake files to get this working on Windows.  

Previously had built it on a Mac, but needed to port my code to Windows and found myself here after 8 hours.

I was about to abandon skia after fooling around for 2 days trying to get vs2017 to compile the lib.  Skia isn't entrenched enough for me in my code, and I'd rather spend time working on replacement libs than fooling with ninja files that don't have the appropriate includes and can't build.

Skia authors:  

Please make the Windows build process smoother - this was a completely unnecessary hassle.  Python+ninja+hack+duct type+hack all on top of what is a very nice library otherwise.  Why such a mess when you have such a nice library?  Just supply rubenvb's cmake file and call it a day.

We (most of the core Skia team) like GN+Ninja.  Chrome uses GN+Ninja.

Keeping a CMakeLists.txt file up to date with with the BUILD.gn files is non-trivial.  Do you have any ideas?

[Mike Klein]

A while back we wrote a pretty barebones GN-to-CMake script (gn/gn_to_cmake.py) for use with IDEs like CLion.  If you like CMake and are adventurous that might be a fun place to look.

[Brian Osman]

I'm also intending to start fresh on my home Windows machine. We've had several reports of people struggling to get a Windows build working, which doesn't match our experience. I'd like to verify that we're not missing something.

@Hal

Apologies for the vent, was pretty frustrated at the time.  I really like the library, but was pretty unhappy about the porting process.  As for ideas, yes...  I have a few.

1. 

I understand your team prefers GN/ninja, that's great and I"m sure there are good reasons - I'm not familiar with that system.  However, I would say that the python/ninja magic you guys are doing (at least on the Windows side) is far more non-trivial than tagging some of your sources in a way that a quick python script can generate a cmake file later down the road and you can hand out.  The cmake file from rubenvb only had a few compiler switches, a few "if androids" and then a bunch of file globs for which files to include.  Not too complex from what I can tell, but I'm no cmake expert.

I'm not a cmake zealot, but it smoked the current deployment process on Windows.  

cmake found my compiler.  (gn/ninja has it hard-coded for "VS Professional" and I was using Community.  No mention in the build docs on that from what I could fine)

cmake found whatever includes/sdk's it needed.  Skia was hardcoded to an older windows SDK, buried in I think a different file than above.

cmake didn't need me to put a pre-bundled python interpreter into my windows path, which is pretty intrusive.

Post the precompiled binaries for Win32 and Win64 from your CI/CD system to the site.  Note in your documentation "While skia definitely builds on Windows (we do it every day in our CI/CD system), our development team is all on Mac and Unix and the Windows process can be a bit daunting if you aren't up to speed on gn/ninja.  We don't run through the build process very often and there may be some issues.  Feel free to use these pre-compiled binaries if you don't feel the need to roll your own.  link here, link here"

3.

Schedule a quarterly "real-life" install, where someone on the team finds a willing co-worker (or intern) and tries to build skia on their Windows machine and truly live the process.  Building skia on an ansible-ised CI/CD VM with all the right dependencies just doesn't transfer to real-life.

Really dig the library, sorry I came off as harsh, you guys do great work.  I built it on my Mac a few months back and it was great.  It's just really frustrating when the docs just say "Build on Windows, no problem" and it's just not the case and I was this close to moving on.

We generally don't host binaries because Skia has neither a stable ABI nor API.  We don't really maintain a version number in the sense you'd expect either.  We also expect clients to want to customize their builds of Skia to suit their needs, mostly around optional dependencies.  There's no stock Skia.

I see.  Guess I'm a rare "stock" user.  :)  Packaged headers and a .lib would have worked for me.  But totally understand if it's an expectation that it's modified by the end user.
