If you install the grass-dev package you get, for example the C header files for the libraries (that's actually most of what you get). You can list all these files using: dpkg --listfiles grass-dev Additionally, you should also get all the compile-time dependencies of GRASS GIS not only the runtime ones which is very useful.

[GRASS-dev] Make Changes to Modules in Grass GIS
Hi all, I have installed ubuntu, downloaded the source code from https://grass.osgeo.org/grass74/source/grass-7.4.1.tar.gz and installed grass-dev package. Since I do not have experience with c can you again briefly explain how to do changes and compile the code. Is the workflow following is correct to do what I intended. 1) copy r.ros folder from grass-7.4.1/raster and rename it as r.new.ros 2) make relevant changes to main.c file in r.new.ros 3) compile the code with 'make' command. * can you explain what the grass-dev package does. Thank you. Have a nice day. BR, Vidura Dantanarayana ___ grass-dev mailing list grass-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-dev
