libvpx - configure for no Assembly code

[Jeyur Patel]

Hi,

 

I am trying to generate vp8 projects/sln for Visual Studio 10 without any assembly files in the projects. I have tried following configure command and it is still looking for yasm or nasm.

 

../configure --target=x86-win32-vs9 --disable-mmx --disable-sse --disable-sse2 --disable-sse3 --disable-ssse3 --disable-sse4_1 --disable-runtime_cpu_detect

 

 

Do we have any simple command line option for configure to disable assembly codes and have only C files in the projects?

 

I also downloaded the “vpx-vp8-debug-src-x86-win32mt-vs9-v1.1.0” src code with pre-build Visual Studio sln, and tried fiddle around the Vpx_config.h and Vpx_config.asm files, but it still includes the assembly files and uses yasm.

 

My aim is to have C only VP8 decoder which compiles, builds and Run in Visual Studio. Any help would be more than welcome.

 

Regards,

Jey

Does it look for yasm at configure time or build time? It is (was?) a
known issue that configure looks for an assembler even though it
doesn't use that assembler during compilation (for visual studio).
This is due to a check in build/make/configure.sh. You may be able to
work around it by specifying --as=yasm to skip the auto detection.

Agree with Johann's suggestion here to get past the configure stage.
Pass --as=yasm, this check is superfluous in visual studio builds.

That should get you there if your goal is to remove the assembly. You
may need to tweak the builds by hand to remove any remaining asm
references, like x86_abi_support.asm or asm_*_offsets, but it
shouldn't affect the build. If your goal is to remove all platform
specific code, additionally edit the vpx_config.h and *.mk files that
it produces to disable ARCH_X86 and ARCH_X86_64.

Not on visual studio. If a gcc build (or other posix-like environment)
works for you, you can configure with --target=generic-gnu to get this
configuration. Cross builds are supported in this configuration too.
