Error on building

[Joilnen]

is glut or freeglut a dependence ?

freeglut is built as part of the project. Are you on Linux? Then likely this command failed: https://github.com/paroj/gltut/blob/2f385318a2fd6d2081639e457bf20b8921ff7bd9/glsdk/CMakeLists.txt#L8

[Joilnen]

yes on linux, archlinux dist

[paroj]

can you run that command manually in glsdk/freeglut

[Joilnen]

works

try building again now

[Joilnen]

I got this error now [joilnen@sutherland gltut]$ cmake --build build/ [ 2%] Built target glload [ 9%] Built target glimg [ 14%] Built target glutil /usr/include/c++/11.2.0/bits/stl_vector.h:1123: std::vector<_Tp, _Alloc>::reference std::vector<_Tp, _Alloc>::front() [with _Tp = cmGccStyleDependency; _Alloc = std::allocator; std::vector<_Tp, _Alloc>::reference = cmGccStyleDependency&]: Assertion '!this->empty()' failed. make[2]: [glsdk/CMakeFiles/freeglut.dir/build.make:477: glsdk/CMakeFiles/freeglut.dir/depend] Aborted (core dumped) make[1]: [CMakeFiles/Makefile2:1785: glsdk/CMakeFiles/freeglut.dir/all] Error 2 make: *** [Makefile:91: all] Error 2

[paroj]

you probably have to either update freeglut manually or use an older compiler
