#35609: gcc @4.7.1 Fails compiling with -m32 on 64-bit system -------------------------------+-------------------------------------------- Reporter: fh@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.1.2 Keywords: gcc, -m32, 64-bit | Port: gcc47 -------------------------------+-------------------------------------------- Hi, gcc 4.7.1 fails to compile the following program with flag -m32 on 64-bit system. {{{ #include <limits> #include <iostream> using namespace std; int main() { cout << numeric_limits<int>::has_infinity << endl; return 0; } }}} The same problem has been discussed for Arch linux here: http://comments.gmane.org/gmane.comp.gcc.help/41605 If I understand well this is a problem of how gcc is built and packaged and not a problem of gcc itself. The output of "g++-mp-4.7 -m32 -v foo.cc" shows that some path is not set properly (see attachment): {{{ ignoring nonexistent directory "/opt/macports/lib/gcc47/gcc/x86_64-apple- darwin10/4.7.1/../../../../../x86_64-apple-darwin10/include" }}} I am running Mac OS 10.6.8 on an Intel Core 2 Duo. I have macports 2.1.2. -- Ticket URL: <https://trac.macports.org/ticket/35609> MacPorts <http://www.macports.org/> Ports system for Mac OS
