Description Florian Badie 2023-11-24 14:35:13 UTC

CMake fails to find the man file in the install step.

Reproducible: Always

Steps to Reproduce:
1. Enable media-gfx/blender man USE flag
2. emerge media-gfx/blender
Actual Results:  
The command fails in the install step.

Expected Results:  
Blender installs correctly with USE="man"

I don't know why I enabled the man USE flag so I'll just install it without it now.

Comment 2 Paul Zander 2023-11-25 12:04:57 UTC

There is a race condition in the install process if USE="man" is set at https://projects.blender.org/blender/blender/src/branch/main/source/creator/CMakeLists.txt#L1805.

I've attached a patch that can be used to install with USE="man" that I'd prefer not to merge and rather get the problem properly fixed.

Comment 4 Sebastian Parborg 2023-11-25 15:59:33 UTC

Are these two upstream PRs related or is this an other issue?

https://projects.blender.org/blender/blender/pulls/115127
https://projects.blender.org/blender/blender/pulls/115320

Comment 5 Paul Zander 2023-11-25 16:24:21 UTC

This is unrelated.

Two cmake targets are created here:
https://projects.blender.org/blender/blender/src/branch/main/source/creator/CMakeLists.txt#L1805

https://projects.blender.org/blender/blender/src/branch/main/source/creator/CMakeLists.txt#L1841

When the install part is run with enough parallelism the second install call is issued before the first one is finished or has even started, because there is no dependency between blender.1 being created and it being installed.

I haven't quite gotten to look for a proper solution yet, because the whole compiling blender.1 in install is not pretty and doesn't fit the preferred workflow in gentoo. I was going to going to open an issue with upstream once I had anything better.
