Let me know if you need more information.

Answer 1

It seems that -nable-werror is enabled by default when creating gdb-7.6.1 on OSX.

 ./configure --disable-werror make 

worked great for me.

Answer 2

The compiler is too picky, so it generates warnings for pointer arithmetic that includes string literals. In addition, you probably configured gdb with --enable-werror or -Werror inherited from somewhere, so these harmless warnings turn into errors. (You only specified configure flags for the compiler, not gdb .)

Solution: disable -Werror or disable this warning using -Wno-string-plus-int (add to CFLAGS )
