Emacs comes from Arch. You can install llvm39-libs.

Installing llvm38-libs solves the problem when the issue if for libLLVM-3.8.so.
As ovruni said, this pkg comes from Arch, so better report this issue at https://bugs.archlinux.org/

@everyone: i have an updated system and my emacs is still launching just fine.

that's just coincidence. in the repos, llvm38-libs is only depended upon by another (broken) [pcr] package: pocl. those packages shouldn't be there anyway, afaict.

but a question remains: what's causing the error for others? maybe a partial upgrade?

@everyone: After Megver83 helped me solve this problem by installing llvm38-libs, emacs worked again.

Today I wanted to update the system and there was a conflict with llvm38-libs. I removed the package, updated, and now emacs won't start again. Thought I could reinstall llvm38-libs but it is no longer in the repos.

Meanwhile emacs shows the same error as before:

emacs: error while loading shared libraries: libLLVM-3.8.so: cannot open shared object file: No such file or directory

Running:

$ LD_DEBUG=files emacs | grep libllvm

returns:

file=libLLVM-3.8.so [0]; needed by /usr/lib/libOpenCL.so.1 [0]

which is in ocl-icd 2.2.11-1 package, which is not installed in my system, yet libOpenCL.so.1 is indeed present in /usr/lib/

Any idea what the matter could be and how to make emacs run again? Should I report and wait for response upstream?

Tried to install ocl-icd (thanks to laust for the suggestion). received a warning of conflict with mesa-libcl (imagemagick listed as depending on it). Removed mesa-libcl and installed ocl-icd. Emacs runs now. Imagemagick seems to work. So far.

i cannot reproduce this. nor does ldd /usr/lib/libOpenCL.so.1 show libLLVM on my computer.

just to add that this seems to be the same issue affecting other programs as well:

https://labs.parabola.nu/issues/1480

Just curious: why is this marked fixed? I hit this bug as well and manual resolution through installation of a dependency doesn't seem like the proper way. Shouldn't ocl-icd be added to dependencies? Why does the emacs (and others) build at all without ocl-icd?

I have Arch installed on another machine and emacs runs fine without llvm39 installed. Until it's fixed, you could at least add llvm39-libs as dependency.
