synth-ruiner I am using the graphical version (i.e. Software Center) for searching, but thanks for pointing out the commandline option. I did a depency frenzy installing everything even vaguely resembling these depencies. Infact the file libbz2.so can be found under /usr/lib64 but somehow Gambas "./configure -C" is not recognizing it ☹️ It is the same with libSDL.so, libSDL_ttf.so, libGL.so, libGLEW.so, libjpeg.so, libpng.so. Or actually there is no libGLEW.so directly but libGLEW.so.2.1, libGLEW.so1.10, libGLEW.so2.1.0 and libGLEW.so1.10.0.
It seems like the endevour of trying or succeeding in compiling Gambas will be some what educative for me at least.
