Linker error when building ufoai 2.5 on OS X 10.8

(1/1)

Hi,

I am trying to build 2.5 on my mac. I have followed the instructions from:
http://ufoai.org/wiki/Coding#Compiling_the_source

When I run "make" it compiles a lot of stuff and then I get this error:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [base/cgame-campaign.dylib] Error 1


--- End code ---

Can anyone please help me with this?
To mee it looks like the linker needs some help finding the 64 bit versions of a lot of libraries, but I really don't know how to fix this..

DarkRain:
Hi,

Could you try running configure with the --enable-hardlinkedcgame option before recompiling?

pete:
Thanks!! That worked! Now the game plays.

DarkRain:
Glad to hear it's working now.

For those who might be wondering: This is a known issue, the cgame-campaign module doesn't link as a library (still WIP), but usually the hard linked cgame option is enabled by default, seems the mac makefiles might need adjustment.
