seems problem solved:

[Comment 16 Alfred Wingate 2023-11-16 18:09:53 UTC]

Its not fixed, still reproducible with sci-libs/gsl and dev-cpp/ms-gsl installed. Similar to https://bugs.gentoo.org/884625#c10

https://github.com/buddhi1980/mandelbulber2/blob/710c70081da246672410fd369dab1df5e5d27379/mandelbulber2/qmake/common.pri#L125

Qmake hardcodes the include, using cmake *may* be better like with calligra where the issue stemmed from a bad cmake find module.

So use cmake and make sure the system cmake find module is used.

(In reply to Alfred Wingate from comment #16)

> So use cmake and make sure the system cmake find module is used.

Their cmakelist is still intended for qt5
Got to tweak it use qt6, would be sad


maybe ms-gsl should install includes to other place like /usr/include/ms-gsl
/usr/include/gsl seems taken by an old open source project

[Comment 18 Jan Henke 2025-04-15 17:35:20 UTC]

This is very much an upstream issue. Unfortunately both projects claim this installation directory for their own header files.

Renaming either package's installation directory leads to us having to patch every consumer too. Since there is other software out there, which expects either of these libs to install their header files there.

Ideally both upstream should resolve this name clash together, but I am not really seeing any effort on either side to work on that.

There is no realy "ownership" of paths under /user/include, therefore, there is also no real owner here.

You'd think the younger project would have a slightly bigger obligation to adapt.

    media-gfx/mandelbulber: fix build when dev-cpp/ms-gsl is installed
    
    By injecting -I/usr/include/gsl, `#include <algorithm>` starts to mean
    "use ms-gsl's algorithm" rather than the C++ stdlib one. But all of the
    includes for ms-gsl here are properly namespaced, e.g. <gsl/foo.h>, so
    we can drop the explicit -I*.
