My problem actually is that a port which I'm preparing requires gfortran which doesn't come with Apple's system gcc but is in port:gcc42. I could simply do "configure.fc ${prefix}/bin/ gfortran-mp-4.2, but what if someone has another gcc installed? I could depends_build on gcc42 but if a gcc suite is required by MacPorts anyways I wouldn't like to impose something which might install another compiler suite unnecessarily.
If you require gfortran, you should depends_build on gcc42. Nevermind anyone who has gcc43 installed; that's beta and shouldn't be relied on until gcc44 is released, at which point the port can be updated. Nevermind anyone who has gcc41 or gc40 or earlier installed; any ports that still depend on those should be updated to gcc42. Oh, I meant to say: and then you go: configure.compiler gcc-4.0
You mean
configure.compiler macports-gcc-4.2
else it doesn't work...
and with depends_build gcc42 that's all you should need.
Yep, works like a charm now!
Well, you need to pay attention: If you have C++ or Objective-C code, it will link to the C++/Objective-C lib of the used compiler. So if you build a C++ program, this needs to be "depends_lib gcc42"! For pure C programs, a "depends_build" is sufficient though. You can check out if your program does this by doing a `otool -L name- of-the-binary-or-dynamic-library'. C++ programs compiled with macports gcc 4.2 will return e.g. '/opt/local/lib/gcc42/libstdc++. 6.dylib'. -Markus --- Markus W. Weissmann http://www.mweissmann.de/ --- Markus W.
