Malformed version number on Mac OSX

[kimkulling]

When building assimp we get the following error on Mac OSX 10.8.
Linking CXX shared library ../lib/libassimp.dylib
ld: malformed 64-bit a.b.c.d.e version number: 3.0.1264
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Changing the SV revision number in the build script from 1264 to 255 solves the problem.

see: https://sourceforge.net/p/assimp/bugs/112/

The issue still happens to this day... If any of a.b.c.d.e in current_version is > 1023, the linker will fail. I'm suspecting that clang only accepts these values between 0 and 2^10 but I don't see any documentation referring to this...

According to the source code https://opensource.apple.com/source/ld64/ld64-274.2/src/ld/Options.cpp.auto.html, the error "malformed 64-bit a.b.c.d.e version number: %s" arises from parseVersionNumber64 that gets called when -dylib_current_version or -current_version is provided in the compiler arguments.

So I tried opening my .xcodeproj file and deleting CURRENT_PROJECT_VERSION and DYLIB_CURRENT_VERSION manually. Compilation succeeded ✔️
