[Mesa-dev] OSMesa 17.1.3 simd16intrin build FAIL on Win/MinGW - 'expected initializer before _simd16_setzero_ps ...'

[Trevor Sandy]

Please help ! My mesa build consistently fails with starting with this log
trace:

src/gallium/drivers/swr/rasterizer/common/simd16intrin.h:127:35: *error*:
expected initializer before '_simd16_setzero_ps'
SIMD16_EMU_AVX512_0(simd16scalar, _simd16_setzero_ps, _mm256_setzero_ps).
Builds on Linux and OSX are unaffected.

You can see a detailed log output for Mesa *17.1.3* at
https://gist.github.com/trevorsandy/0f8f83a9f8963911d5a42f8723c772fb and
the same

I have been chasing this issue for the past week without success. I've read
the content at Mesa3D.org and search across the mail archives. I've also
followed the documented dev env requirements.

The gist URLs above provide a detailed capture of the installation output -
based on this customized install script.
