i didnt say it would. dynamic libs (like libdirectfb.so) should have a DT_NEEDED entry for libm.so and that should be sufficient for -ldirecttfb. thus -lm should be necessary only for static linking. if libdirectfb.so is not linked against -lm, then the generation of the shared lib is broken. but that doesnt mean the .pc should be hacked with an entry in Libs: to work around it. lack of real details as to what is failing makes helping find the right fix much harder. -mike
