Build failure on Windows through cygwin

[ARaj]

Hi,

I am trying to build glibc-compat(which is a dependency to build curl) from naclports in a Windows environment.

I downloaded depot_tools, naclports and nacl sdk and chose pepper version to be 40. I am doing this in cygwin like mentioned in the home page of naclports.

My build fails with the following error:

$ NACL_ARCH=pnacl make glibc-compat

bin/naclports install glibc-compat -v --verbose-build

IsInstalled: glibc-compat -> False

Prebuilt package was built with different SDK version: 38 vs 40

mkdir: /home/arajp/naclports/src/out/logs

I do have netdb.h at /home/arajp/nacl_sdk/pepper_40//include/pnacl/netdb.h which is mentioned as an include directory in the command, but the command still fails.

Can someone help me in resolving this issue?

Hi Araj,


I don't see anything obviously wrong here. Can you try running the
highlighted comment from within the directory mentioned right about
it, but add a -v to the end of the command? This should show the
include paths actually arguments to clang.

Does the package build with newlib toolchain (simply remove
NACL_ARCH=pnacl from your commandline)?

cheers,
sam

I isolated the problem a little more. It appears to me that the compiler has problems with filenames given as absolute paths. For eg.

/home/arajp/nacl_sdk/pepper_canary/toolchain/win_pnacl/bin/pnacl-clang -c /home/arajp/test.c doesn't work but

cd /home/ && /home/arajp/nacl_sdk/pepper_canary/toolchain/win_pnacl/bin/pnacl-clang -c arajp/test.c works

In the failure case it reports errors like:
clang.exe: error: no such file or directory: '/home/arajp/test.c'
clang.exe: error: no input files

It is the same behavior with pepper_canary as well as pepper_40. Please note that I am doing this in cygwin environment.

[ARaj]

It is the same problem with newlib toolchain as well.

Can someone help me in resolving this issue? Is the compiler win_pnacl/bin/pnacl-clang compiled for working with Cygwin? Is Cygwin the right environment to compile naclports on Windows?

Any inputs are highly appreciated.

Windows is not the right environment to compile naclports period. Once upon time we've tried to make naclports compatible with cygwin, but it was hard work for very little reward. Especially since "root" of cygwin keeps wandering around as described in the following document:

https://web.archive.org/web/20130308023124/http://www.chromium.org/nativeclient/design-documents/building-a-hermetic-toolchain-on-cygwin

You can try to build naclports on cygwin and it may even work for some packages, but you are entirely on your own there. You'll need to create few symlinks to make sure all components will see all the files and then it kinda sorta works for some packages. Not for all, though, we've never had a situation where cygwin was suitable for more than a handful simplest packages.

It's much simpler and easier to build packages under Linux and then use artifacts in your Windows project rather than try and fight cygwin to build everything under Windows.
