I get that warning on my box too. CFLAGS="-march=amdfam10 -O2 -pipe" in my case. Standard FEATURES.
I think there is an "#include <math.h>" missing. I also get the following error: x86_64-pc-linux-gnu-gcc -march=amdfam10 -O2 -pipe -Wl,-O1 -Wl,--as-needed -o raton main.o support.o interface.o callbacks.o midicontrol.o -lgtk-x11-2.0 -lgdk-x11-2.0 -lpangocairo-1.0 -latk-1.0 -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lpangoft2-1.0 -lpango-1.0 -lgobject-2.0 -lglib-2.0 -lfreetype -lfontconfig -lasound /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.2/../../../../x86_64-pc-linux-gnu/bin/ld: callbacks.o: undefined reference to symbol 'sin@@GLIBC_2.2.5' /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.2/../../../../x86_64-pc-linux-gnu/bin/ld: note: 'sin@@GLIBC_2.2.5' is defined in DSO /lib64/libm.so.6 so try adding it to the linker command line /lib64/libm.so.6: could not read symbols: Invalid operation collect2: error: ld returned 1 exit status I have fixed these types of bugs before so I can fix it. The -lm is missing.
