Here 'time make install' *after* make install says this: real 1m56.868s user 0m29.270s sys 0m17.049s And 'touch ../../gtk+/gtk/gtktextview.c && time make' produces this: real 1m17.363s user 0m30.982s sys 0m15.749s Somehow libtool relinks every library on 'make install', and relinks every library which depends on libgtk on 'make' if libgtk was rebuilt. > In my specific case however, just a single .c file had to be recompiled > in every go, and linked with the rest of the object files to make libgtk+. Are you sure you were talking about toplevel gtk directory, not about 'make' inside gtk+/gtk? Because that says: touch ../../../gtk+/gtk/gtktextview.c && time make real 0m23.437s user 0m10.881s sys 0m3.368s Disabling tests would make things faster, but only inside gtk+/gtk, if you go up then you get modules (many) relinked anyway.
