Issue #8 resolved

build fails on fedora-16 due to missing -lm

created an issue

Linking C executable copyrotated /usr/bin/ld: CMakeFiles/copyrotated.dir/copyrotated.o: undefined reference to symbol 'sin@@GLIBC_2.2.5' /usr/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: ld returned 1 exit status make[2]: [examples/copyrotated] Error 1 make[1]: [examples/CMakeFiles/copyrotated.dir/all] Error 2 make: *** [all] Error 2

===========================

configure.ac has tests for -lm - I guess copyrotated isn't using that?

Not sure thus is the right fix, but I was able to workaround with:

    I ran into the same problem building on a LFS 7.1 system and can verify that John Ellson's patch allows gd to compile successfully.
