Hi, Has anyone managed to compile itk1.6 with shared libs? I tried to do it. I get the following message : ld: common symbols not allowed with MH_DYLIB output format with the -multi_module option rpoly.o definition of common _global_ (size 4232) /usr/bin/libtool: internal link edit command failed I'm using gcc 3.3 and cmake1.8 on MacOSX 10.2.8. Thanks, florence
