Linking problem after porting to Mac OSX (_compress/_uncompress)

[Daniel Wetzler]

Hallo,

I try to port a little applications which runs on Linux
to OS X. If I try to compile/link it, the linker throws out the
following error :

ld -arch ppc -dynamic -o cluster.exe -lcrt1.o -lcrt2.o
-L/Library/MySQL/lib/mysql -L/usr/lib/gcc/darwin/3.3
-L/usr/lib/gcc/darwin -L/usr/libexec/gcc/darwin/ppc/3.3/../../..
aminosaeure.o atom.o main.o loop.o cluster.o protein.o -lmysqlclient
-lstdc++ -lm -lgcc -lSystem |
c++filt3
ld: Undefined symbols:
_compress
_uncompress
make: *** [cluster.exe] Error 1


I don't know what this could mean. I espacially don't know what
this compress / uncompress thing means.

Can anyone help me ?

Greetings,

Daniel Wetzler
