Can anyone help me? I am new at this GPC thing, and the whole compiler thing in general. On OSX, I did the package installation, which seemed pretty simple, and no problems were reported. But when I try to compile something on the command line using gpc <filename>, I get back the following error (or some variant of it): gpc: installation problem, cannot exec `c++filt3': No such file or directory /usr/bin/ld: /usr/lib/libSystem.dylib load command 9 unknown cmd field collect2: ld returned 1 exit status Interestingly, when there are problems in the code, gpc seems to have no problem pointing them out. It seems the problem only comes when the code is good and about to be compiled. Sorry if my terminology is wrong, I'm still learning how to talk like this. Thanks in advance for any suggestions!
