Title:
LLVM symbols should be versioned to avoid crashing applications that
load mesa's swrast and also use a different libLLVM
Status in llvm-toolchain-3.8 package in Ubuntu:
Confirmed
Bug description:
The libgl1-mesa-dri-lts-xenial package depend on libLLVM-3.8.so.1 from
the libllvm3.8v4 package; this library gets used when using software
OpenGL rendering on a remote display. As a result, applications based
on Qt5 that also use libLLVM features provided by another (newer) LLVM
version will crash when invoked from a remote X terminal.
Example: KDevelop5 uses libclang (and this libLLVM) for C/C++ parsing;
I build it to use the LLVM/Clang 4.0 packages from llvm.org (and self-
built Qt5 and KF5 libraries) and can thus not render to a remote X
server (XQuartz on my Mac).
There is an upstream LLVM patch which solves the issue by adding
versioning info to libLLVM:
https://bugs.kde.org/show_bug.cgi?id=373614
https://reviews.llvm.org/D31524
Please consider backporting this patch to LLVM 3.8 (or rebuilding the
mesa package to use a (much) more recent LLVM version that already
contains the patch).
