It's the usual crap that programs make use of sse2 without checking cpuid AT DAMN RUNTIME.
webkit2gtk3 build log: [ 64s] -- Performing Test C_COMPILER_SUPPORTS_-msse2 [ 65s] -- Performing Test C_COMPILER_SUPPORTS_-msse2 - Success [ 65s] -- Performing Test C_COMPILER_SUPPORTS_-mfpmath=sse [ 65s] -- Performing Test C_COMPILER_SUPPORTS_-mfpmath=sse - Success [ 65s] -- Performing Test CXX_COMPILER_SUPPORTS_-msse2 [ 65s] -- Performing Test CXX_COMPILER_SUPPORTS_-msse2 - Success [ 65s] -- Performing Test CXX_COMPILER_SUPPORTS_-mfpmath=sse [ 65s] -- Performing Test CXX_COMPILER_SUPPORTS_-mfpmath=sse - Success
Glad to see that the processor is not yet entirely unsupported. Shall I open a bug report for this problem?
That will be tough: webkit2gtk claims in the CMake files:
include(DetectSSE2) if (NOT SSE2_SUPPORT_FOUND) message(FATAL_ERROR "SSE2 support is required to compile WebKit") endif ()
Wonderful! It forces its requirements on every piece of the software stack that depends on it. However, I wonder what they do on arm.
Probably, it is excessive requirement. Is there any assembler inline code in the project?
I don't strictly depend on Gnome. I use the machine for kernel development and Gnome/X11 is just one of my smoke tests. Twm works nicely BTW! :)
Best regards Thomas
Cheers, Dominique
