Compilation fails

[Azrael3000]

I used the first method of compiling, i.e. cd src && make but this fails because CCD_EXPORT is not set. In detail:

$ make USE_DOUBLE=yes cc -Wall -pedantic --std=gnu99 -I. -fvisibility=hidden -c -o support.o support.c In file included from support.c:18:0: support.h:40:12: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘void’ CCD_EXPORT void __ccdSupport(const void *obj1, const void *obj2, ^ Makefile:35: recipe for target 'support.o' failed make: *** [support.o] Error 1
