CMAKE might be the culprit if the generation of libLLVM.so file ( 3.7.0 version ) has problems, I found two interesting links about the "CMAKE way" when building LLVM 3.7.0 : <a href="https://llvm.org/bugs/show_bug.cgi?id=23649">https://llvm.org/bugs/show_bug.cgi?id=23649</a> <a href="http://lists.freedesktop.org/archives/mesa-dev/2015-September/095696.html">http://lists.freedesktop.org/archives/mesa-dev/2015-September/095696.html</a> and I found also that archlinux developers for the 3.6.2 version of LLVM have used the classic way ( ./configure, make, make install ) for building LLVM 3.6.2, then for the 3.7.0 version they have switched ( archlinux developers ) to the CMAKE build method, LLVM 3.6.2 lib works without problems with mesa 11.0.3, LLVM 3.7.0 lib triggers a crash when mesa 11.0.3 tries to use it ( when r600 driver is used with an amd radeon HD4650 pcie card ), it's just a supposition : my bug could be the consequence of the switch to the CMAKE build method, something went wrong in CMAKE files configuration in LLVM 3.7.0, to be sure I am currently trying to compile LLVM 3.7.0 with the classic way ( ./configure ) by reverting this patch in order to allow this : <a href="http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20150629/284970.html">http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20150629/284970.html</a> and I will see if the bug is still here when libLLVM.so.3.7 is building with ./configure and not CMAKE</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
