cross compiling arm: Atomic operations not supported

[JonnyX]

I want to cross compile CEF for arm architecture on ubuntu14.04.

I have used the automate-git.py script for cloning repos and compiling.

used environmet variables:
GYP_GENERATORS=ninja
GYP_CROSSCOMPILE=1
GYP_DEFINES=target_arch=arm arm_float_abi=hard component=shared_library


Compiling ends with an error on the libcef_dll_wrapper target:

I read something about defining BUILDING_CEF_SHARED variable.
Doing this, brings me to other errors: OVERRIDE variable not defined
After defining OVERRIDE internal:: namespace problems did appear.

I have also tried other cef branches (2357, 2272) but there are the same problems.
What did I make wrong?

Is there anyone, how has successfully cross compiled CEF for arm

Thanks,
Jonny

In file include/base/cef_atomicops.h replace

Code: Select all

#include "include/base/internal/cef_atomicops_x86_gcc.h"
#else


by

Code: Select all

 #include "include/base/internal/cef_atomicops_x86_gcc.h"
#elif defined(COMPILER_GCC) && defined(__ARM_ARCH)
#include "include/base/internal/cef_atomicops_arm_gcc.h"
#else


Copy cef_atomicops_arm_gcc.h in include/base/internal/. This is a file from chromium source code.

[JonnyX]

thank you so much,
where did you find this information?

the error has gone away but now libcef can't be linked because of many undefined references.

The attached file contains the complete error output.

I'm not familiar with ninja and clang.
Is it possible, that same gyp files need to be patched?
In the out/Release/obj/.. the object files from the missing references are there.

The strage thing is that the x64 build works fine.
I would be truly grateful about any tips.

[crast]

Try this
GYP_DEFINES=target_arch=arm arm_float_abi=hard

[JonnyX]

Thanks a lot!

Now it compiles and can be executed on arm.

[ashutoshd]

I am also trying to cross compile CEF for ARM platform.

I read your posts and it looks that you were already using "target_arch=arm arm_float_abi=hard" configuration.
What change you made to get rid of compilation errors?
Did you drop "component=shared_library" instead?
