[Mesa-dev] Build mesa-dev on Windows with AVX instruction set problem

[Fabrício Ceolin]

Hi,

I am trying to build mesa-dev on windows.

I am learning how to do it, through the project https://github.com/
pal1000/mesa-dist-win/tree/master/buildscript

I tried to use the binaries from pal1000, but I got an illegal instruction
problem in opengl32.dll when I tried to run my application (VTK based).

00007FF96252B0CF  cmp         qword ptr [rdx+18h],10h
00007FF96252B0D4  mov         rbp,qword ptr [rdx+10h]
00007FF96252B0D8  jb
std::basic_string<char,std::char_traits<char>,std::allocator<char>
>::basic_string<char,std::char_traits<char>,std::allocator<char> >+2Dh
(07FF96252B0DDh)
00007FF96252B0DA  mov         rsi,qword ptr [rdx]
00007FF96252B0DD  cmp         rbp,10h
00007FF96252B0E1  jae
 std::basic_string<char,std::char_traits<char>,std::allocator<char>
>::basic_string<char,std::char_traits<char>,std::allocator<char> >+5Ah
(07FF96252B10Ah)
*00007FF96252B0E3  vmovups     xmm0,xmmword ptr [rsi]  *
00007FF96252B0E7  vmovups     xmmword ptr [rcx],xmm0
00007FF96252B0EB  mov         qword ptr [rcx+10h],rbp

I tried to build everything on a target machine, but the problem was not
solved.

I saw here that movups is in avx instruction set here
http://www.felixcloutier.com/x86/MOVUPS.html

My target machine has the following cpuinfo (inside msys64):

cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 6
model name      : QEMU Virtual CPU version 2.0.0
stepping        : 3
cpu MHz         : 2993.000
cache size      : 4096 KB
fpu             : yes
fpu_exception   : yes
cpuid level     : 4
wp              : yes
flags           : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 clflush mmx fxsr sse sse2 pni vmx cx16 x2apic popcnt hypervisor
lahf_lm epb dtherm fsgsbase tsc_adjust bmi1 hle avx2 clflushopt
clflush size    : 64
cache_alignment : 64
address sizes   : 40 bits physical, 48 bits virtual
power management:

How can I compile opengl32.dll without use the avx instruction set?

My compilation command was (from mesa-dist-win):

python c:\Python27\Scripts\scons.py build=release platform=windows
machine=x86_64 swr=1 libgl-gdi osmesa graw-gdi

Thanks
