Description Jon Daniel 2023-01-14 20:49:36 UTC

Adding a link with `ln -s /usr/include //include` compiles but doesn't fix the ebuild

Reproducible: Always

Steps to Reproduce:
1. emerge -v sdl2-ttf
Actual Results:  
Abort: Fails to locate SDL2_INCLUDE_DIR

Expected Results:  
Compile and install locating SDL2_INCLUDE_DIR as /usr/include not //include

Please include the full build.log and emerge --info (with the symlink removed).

emerge --info too please if not already working on it. It might be an issue with CMake (which is fixed in portage git).

Comment 4 Jon Daniel 2023-01-14 21:11:45 UTC

The line of code in question is located at /lib/cmake/SDL2/sdl2-config.cmake:17

get_file_component(prefix "${CMAKE_CURRENT_LIST_DIR}/../../../" ABSOLUTE)

${CMAKE_CURRENT_LIST_DIR} is set to /lib/cmake/SDL2

So this seems to be related to the usr-merge transition

Yes, that's what I was suspecting, hence asking about emerge --info.

Any chance you could try portage-9999 briefly and report if it helps?

The bug is triggered in dev-util/cmake-3.25.1

Adding GetRealPath to CollapseFullPath resolves the issue.
