Hi, I have spent the last couple of days looking into what should be a reasonably general method for packaging cross compilers. You can get my PKGBUILDs for a i686-pc-mingw32 cross-compiler from http://allanmcrae.com/packages/cross-i686-pc-mingw32.tar.gz . They can probably use more work, but the general idea is there. The basic principles I came up with are: 1) define these variables _target=i686-pc-mingw32 _sysroot=/usr/lib/${_target} pkgname=cross-${_target}-<program> 2) build most stuff using: --prefix=${_sysroot} --sysroot=${_sysroot} 3) add symlinks for all ${_sysroot}/bin/${_target}-* to /usr/bin An amusing anecdote... the result from building "Hello World!" for Windows using this cross compiler resulted in binary which AntiVir said had a virus. Strip that binary and all was OK! Allan
