You only need to install g++-multilib and ia32-libs. However there is no ia32-libs-dev package (and no plan to create one). Just using the 64bit system headers may lead to unexpected results.
see bug 117131 for the corresponding ia32-libs report. I'll close this report as "wontfix" after a while. ** Changed in: gcc-defaults (Ubuntu) Sourcepackagename: gcc-4.1 => gcc-defaults -- [Wishlist] gcc-x86-32-cross compiler meta-package https://bugs.launchpad.net/bugs/144311 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
