I have Debian Unstable AMD64 on a truly 64-bit CPU (Intel Core 2 Quad) but still I have this failure: Code: checking whether ccache gcc -m32 works... no configure: error: Cannot build a 32-bit program, you need to install 32-bit development libraries. With 32-bit packages it worked like a charm. :) On my system I just need to call "./configure" to get it working. I have the following extra environment variables: Code: declare -x CXX="ccache g++" declare -x CXXFLAGS="-g -O0" declare -x CC="ccache gcc" So compilation of so much code doesn't hurt so much... ;) And gives nice trackbacks for debugging. I tried to following these instructions (http://wiki.winehq.org/WineOn64bit#head-64ba498d52dd0a3ccae1c52c5d913d7aa692f9b1) but they ended up with this: Code: # apt-get install ia32-apt-get Reading package lists... Done Building dependency tree Reading state information... Done Package ia32-apt-get is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package ia32-apt-get has no installation candidate Do I need some special repositories? I have usual plus some extra repos not relevant for Wine. Any help is much appreciated. :) Q
