[Mesa-dev] lvm pipe crash under windows

[Jason Anderssen]

Hi All,

I thought I would share for the benefits of anyone in a similar issue like
me one day.
I think the cause is the processors being used are xeon, and they don¹t
support sse extensions.
I thought maybe the 3.4 version of LLVM must have a bug in detecting this
processor, so I tried 3.6.2 of LLVM, and it all works now. (I read through
forums, and notice 3.7 had some processors bug detection issues, and 3.8
would not link with MESA for me:( )
So since I feel my outcome is correct, does anyone have a ŒMESA¹
recommended way to fix this, I see that on the Mesa site, the recommended
LVM is 3.4, however this obviously won¹t suffice, so this is the reason I
ask simply for a recommended combination I should be using.

I tried LLVM 3.8 and the latest Mesa, but I get some really weird linkage
issues, happy to go back and try further with this if necessary?

Cheers
Jason
