<div dir="ltr"><div>Hi Patrick,<br><br></div>Which OS and Compiler are you using? Also what version of binutils are you using (`which ld` and `ld --version`)? This is a known issue where the `ld` shipped with older versions binutils doesn't support the AVX2 instructions generated for SWR, even though the compiler you're using does. Disabling SWR isn't really a great option since it's performance is dramatically better than the llvmpipe alternative. Placing a newer binutils in your path should let SWR build successfully.<br><div class="gmail_extra"><br clear="all"><div><div class="m_3840047217321977022gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">----------<br>Chuck Atkins<br>Staff R&D Engineer, Scientific Computing<br>Kitware, Inc.<br></div></div></div></div></div></div></div><br><div class="gmail_quote">On Wed, Apr 19, 2017 at 11:47 AM, Patrick Begou <span dir="ltr"><<a href="mailto:Patrick.Begou@legi.grenoble-inp.fr" target="_blank">Patrick.Begou@legi.grenoble-<wbr>inp.fr</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">My work to compile paraview 5.3 is in progress but on the cluster (no GPU) I fail to compile osmesa.<br>
The downloaded tarball is mesa-17.0.1.tar.xz<br>
<br>
The message is about invalid instructions:<br>

I use Python 2.7.9 with mako, gcc (GCC) 4.8.1 and the configure command generated by paraview-superbuild process in superbuild/osmesa/src is:<br>
<br>
./configure --prefix=/kareline/data/begou/<wbr>PARAVIEW5/build-kareline/insta<wbr>ll<br>
--enable-opengl --disable-gles1 --disable-gles2 --disable-va --disable-xvmc --disable-vdpau<br>

--with-gallium-drivers=swrast,<wbr>swr --disable-dri --with-dri-drivers= --disable-egl --with-egl-platforms=<br>
--disable-gbm --disable-glx<br>
<br>
It seams the same as the one provided in the wiki.<br>
<br>
I've no idea on how to work around this...<br>
<br>
Thanks<br>
