Created attachment 545506 [details] /usr/lib64/pkgconfig/grass.pc I try to install the addon v.in.gps via the built in extension manager. ## error 1, which I could fix: in the GRASS console python complained about a missing file "docs/html/grass_logo.png" solved by cd /usr/lib64/grass74 mkdir docs && cd docs ln -s /usr/share/doc/grass-7.4.0/html ./ ## error 2 which I could not fix: now, when I try to install v.in.gps, I get (Thu Aug 30 14:30:52 2018) g.extension extension=v.in.gps url= Fetching <v.in.gps> from GRASS GIS Addons repository (be patient)... Compiling... ERROR: Please install GRASS development package (Thu Aug 30 14:30:54 2018) Command finished (1 sec) also, in a terminal: $ grass74 --config ERROR: Please install the GRASS GIS development package Exiting... while inspecting the contents of the craved for dev-package in debian, I noticed, that they installed includes whithin /usr/lib64/grass74/include/grass/*.h, which led me to try making a symlink to /usr/include/grass, similar to the documentation one. That didn't help. I then noticed the pkg-config files that are included in debian. I found /usr/lib64/pkgconfig/grass.pc (attached) which looks horibly wrong, since none of the included paths exist on my system. I tried changing them to what I was thinking where the right directories, but still got the same error message. After reinstalling grass this file is now again in its initial (obviously wrong?) state.
