[gentoo-user] kdevelop broken (llvm slot issue)

[Alexander Puchmayr]

Hi there,

After recent upgrades of mesa, llvm, clang etc kdevelop does not work anymore. 
It crashes immediately after start with errors 

: CommandLine Error: Option 'help-list' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options

This issue is covered by bug https://bugs.gentoo.org/651658, which is open 
since March 2018 and no progress since also March 2018.

It seems as if multiple slots of llvm cause the problems. mesa pulls in llvm:
5, while other programs pull in llvm:6 (via clang:6)

Does anyone have an idea how to get a working kdevelop again?

Regards
	Alex

Have you tried disabling the llvm USE flag of mesa? AFAIK it's only used 
for the software rendering backend, which you probably don't need. Try 
disabling it, and then do:

   emerge -auDN --changed-deps --with-bdeps=y @world

followed by:

   emerge -a --depclean

which should unmerge llvm:5.

I think you have to not have multiple LLVM/Clang installations,
unfortunately. That's what the bug indicates.

I am not having issues with KDevelop with Clang support and I have
everything on the latest version:

LLVM 6.0.1-r1 libffi ncurses
Clang 6.0.1 +static-analyzer LLVM_TARGETS="AMDGPU BPF NVPTX X86"
KDevelop 5.2.3 gdbui hex plasma qmake welcomepage
kDevelop-php 5.2.3
kdevelop-python 5.2.3
Mesa 18.* classic dri3 egl gallium gbm gles2 llvm wayland

Most of the above are defaults.

I would just ensure everything is built against one version of
Clang/LLVM and get rid of the other versions from the machine.

If you really don't need the Clang features (if you are using KDevelop
for non-C/C++), you can disable it at runtime:

/usr/bin/env KDEV_DISABLE_PLUGINS=kdevclangsupport kdevelop %u

You have to kill all KDevelop instances completely for this to work.

I have this is in my menu because KDevelop gets dumb with QML JS vs
JavaScript for me, making KDevelop nearly impossible to use with Node
projects.

Thanks for the quick response. Upgrading to mesa 18 solves the problem.
