Qt Creator profiling tools missing `perfparser`

[miniBill]

Describe the bug Qt Creator profiling tools are not working because of a missing prerequisite: perfparser.

To Reproduce Steps to reproduce the behavior:

1. Start Qt Creator with a simple C/C++ project
2. In the Analyze menu choose the Performance Analyzer command
3. You get the following error:

Could not start the perfparser utility program.
Make sure a working Perf parser is available at the location given
by the PERFPROFILER_PARSER_FILEPATH environment variable.

perfparser is indeed missing.

Expected behavior The program gets profiled.

For what it's worth, on a different distro I had this same problem which was resolved by installing elfutils-devel and then recompiling qt-creator. The build silently skips building this tool if this dependency is absent.

@loops would you be able to point me in the general direction of making this happen on NixOS?

Test #139938

@Artturin I still get "Could not start the perfparser utility program. Make sure a working Perf parser is available at the location given by the PERFPROFILER_PARSER_FILEPATH environment variable."

[Artturin]

try now

[Artturin]

updated, cancel the build and try again

... I still get "Could not start the perfparser utility program. Make sure a working Perf parser is available at the location given by the PERFPROFILER_PARSER_FILEPATH environment variable." What am I doing wrong?

[Artturin]

Which channel are you following, if unstable then have you updated

[miniBill]

I'm using fetchTarball "https://github.com/Artturin/nixpkgs/archive/d920c1463c0c038846e49a50c2c7737413535e8b.tar.gz" from home-manager (which is the first commit that includes the patch)

[Artturin]

try this https://github.com/NixOS/nixpkgs/pull/140693

[miniBill]

It still doesn't work for me :(

[Artturin]

looks like perfparser is actually a program built by qtcreator

i've switched the pr to be a update pr so that we get perfparser

[ar7eniyan]

On the current version from master (16.0.2), the perfparser executable gets placed into $out/libexec/qtcreator/, so it's not available in ${lib.getBin perf}/bin (and perhaps never was). The issue is still relevant. A simple fix would be to just replace the second path with the first.

Can I tag someone to reopen the issue? Maybe @SuperSandro2000...
