--- Comment #9 from Dylan Baker  ---
Can you try building with git tip again? A patch just landed that fixes the way
the meson build calculates the LLVM version string for the pre-processor. I'm
not sure if that will fix it, but it's worth trying. If it doesn't I'll install
fedora and see if I can reproduce and fix it.

I can reproduce on Fedora 27 and Fedora 28 (rawhide) with various LLVM versions
from 3.9 onwards. What info could be helpful?

I rebuilt llvm with LLVM_LINK_LLVM_DYLIB.
That now installs lots of .sa libraries  and an enormous
/usr/lib/libLLVM-5.0.so

I then auccessfully rebuilt mesa using autotools, but the mesaon build still
fails, although with a much shorter list of link libraries.

log of autotools build

autotools builds master branch, however some of the options are different

(In reply to tjbugs from comment #3)

Don't enable BUILD_SHARED_LIBS, it's only for LLVM developers. Enable
LLVM_LINK_LLVM_DYLIB instead.

1. I reverted to meson-0.43.0 built from the release tarball.
2. I am now using llvm-5.0.0 built from the release tarball, with the following
options:
-DLLVM_ENABLE_ZLIB=1 -DLLVM_ENABLE_FFI=1 -DLLVM_TARGETS_TO_BUILD=AMDGPU;X86
-DBUILD_SHARED_LIBS=1 -DCMAKE_BUILD_TYPE=RELEASE
INSTALL_PREFIX=/usr
3. I now specify buildtype=plain

the mesa build still fails in the same way using git commit
57372c5a42969afe6c7afd6a0389a92e3e1a5178

4. I will now try to build the same code using autotools.
I know that the 17.3 branch builds correctly using autotools.

Also, I noticed you're using meson from git, are you building with upstream
master, or do you have additional patches?

I'm having trouble reproducing your problem. I have gcc 7.2.0 and LLVM 5.0.0
and with the same options:

CFLAGS="-march=native -mtune=native -m64 -pipe -O3" CXXFLAGS="-march=native
-mtune=native -m64 -pipe -O3" meson build -Ddri-drivers=r200
-Dgallium-drivers=swrast -Dvulkan-drivers=amd -Dplatforms=x11,wayland,drm
-Dglx=dri -Dgles1=false -Dgles2=false -Dvalgrind=false -Dlibunwind=false
-Dselinux=false -Dosmesa=gallium

It compiles and links fine for me.

As an aside, since you're passing -O3, you should also pass --buildtype=plain,
so that meson doesn't add -g and -O options.

Two questions for you:
Are you compiling LLVM yourself?
Does the build work with autotools?

Bug ID: 103543
   Summary: meson targets which link libgallium.a have unresolved
symbol llvm::RTDyldMemoryManager
   Product: Mesa
   Version: git
  Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
  Severity: normal
  Priority: medium
 Component: Other
  Assignee: mesa-dev@lists.freedesktop.org
  Reporter: tjb...@scarlet.be
QA Contact: mesa-dev@lists.freedesktop.org

full compile log

src/gallium/auxiliary/libgallium.a(gallivm_lp_bld_misc.cpp.o):(.data.rel.ro._ZTI26DelegatingJITMemoryManager[_ZTI26DelegatingJITMemoryManager]+0x10):
undefined reference to `typeinfo for llvm::RTDyldMemoryManager'

I tried various options, but anything involving llvm fails for me
[1290/1291] Linking target src/gallium/targets/osmesa/libOSMesa.so.8.0.0.
FAILED: src/gallium/targets/osmesa/libOSMesa.so.8.0.0
[1291/1291] Linking target src/gallium/targets/dri/libgallium_dri.so.
FAILED: src/gallium/targets/dri/libgallium_dri.so

I need radeon support.
full compile log attached.
I used these options:

dri-drivers=r200
gallium-drivers=swrast
vulkan-drivers=amd
osmesa=gallium
platforms=x11,wayland,drm
glx=dri
gles1=false gles2=false
valgrind=false libunwind=false selinux=false 

using llvm-5.0.0; I also tried 5.0.1 and 6
gcc-7.2.0

I got something similar trying mesa-17.3, however the autotools build works in
that case.
