Unable to build in WSL ubuntu (cross compile)

[spoiledsport]

I am unable to cross compile in Windows 10 WSL. Any idea what the problem could be? This is the last part of the build log. I am running the command
make CROSS_COMPILE=i686-w64-mingw32- -C tools/lkl

This is because you need patched binutils. See issue #289

EDIT: Issue #289 is about building on windows so unrelated, but you still need patched binutils. You can find pre-compiled binaries in tools/lkl/bin/ https://github.com/lkl/linux/tree/master/tools/lkl/bin . It should work if you add them in your $PATH

[spoiledsport]

Even using those binaries, the build failed. I also have the same problem using Ubuntu 16.4 image running under Hyper-V on Windows 10. Anything else that I should be doing? Any commands I should run to verify that I am using the right version of binutils? I am also going to try to build under Windows with MSYS2 and see what happens.

Please let me know what you guys think

[Rondom]

You can find pre-compiled binaries in tools/lkl/bin/ https://github.com/lkl/linux/tree/master/tools/lkl/bin . It should work if you add them in your $PATH

@petrosagg Unfortunately no. If I remember it correctly, it does not work if you put them into the path. GCC will call the LD that is in the same directory as itself. It will not look in the path. I learned this the hard way myself :-(

(It has been some time, so please double-check and confirm that what I write above is correct)

[spoiledsport]

Can you share you binary (64 or 32 bit) for windows if you have it, please? I also tried building in MSYS2 and I am not able to either. With the 64 bit shell, I am getting

$ make -C tools/lkl
make: Entering directory '/e/Dev/GitHub/lkl/linux/tools/lkl'
Makefile:78: *** Unrecognized platform: pe-x86-64. Stop.
make: Leaving directory '/e/Dev/GitHub/lkl/linux/tools/lkl'

With the 32 bit shell

$ make -C tools/lkl
make: Entering directory '/e/Dev/GitHub/lkl/linux/tools/lkl'
HOSTCC scripts/basic/fixdep
scripts/basic/fixdep.c:107:22: fatal error: sys/mman.h: No such file or directory

[petrosagg]

@spoiledsport I tested on my machine and the build is definitely using the ld from tools/lkl/bin, I deleted the system wide one and it ran fine. I'm building using make -j4 CROSS_COMPILE=i686-w64-mingw32- -C tools/lkl on Arch linux.

If you didn't build binutils for MSYS2 from source or didn't put tools/lkl/bin in your path (using absolute paths) and used CROSS_COMPILE=i686-w64-mingw32- then you're probably using the wrong binaries.

I'm attaching the built dll for windows lkl-pe-i386.zip. It's .xz compressed in a zip because Github only allows zip files up to 10MB.

[petrosagg]

Regarding the Ming32 shell, I also never managed to make it work and was getting the same error.

[spoiledsport]

Thanks for helping on this one. I was able to get my compile to work by removing the files in /usr/bin. I am able to build the dll
:-)

You have been very helpful. Is this dll 32 bit then? If there any way to create a 64 bit?

Once again, thanks for all your help. I really appreciate your sticking with me on this one.

[Rondom]

64-bit is not supported on Windows: #25
