Hello. I would like to port GHC to mips64el. I have never tried cross-building before. So I will probably post more questions later. Actually, I am not sure that I am using the right term. I am going to use my i686 machine to build GHC for mips64el. In terms of this page(0): B = i686-unknown-linux H = mips64el-unknown-linux T = mips64el-unknown-linux Is the above correct? What I did: 1. Downloaded this(1) tarball (on i686) and unpacked it. 2. Executed the following commands(2): ghc-7.6.1$ cp /bin/pwd utils/ghc-pwd/ghc-pwd ghc-7.6.1$ perl boot ghc-7.6.1$ ./configure --enable-hc-boot --build=i686-unknown-linux --host=mips64el-unknown-linux --target=mips64el-unknown-linux Output: checking for gfind... no checking for find... /usr/bin/find checking for sort... /usr/bin/sort checking for ghc... /usr/bin/ghc checking version of ghc... 6.12.1 checking build system type... i686-unknown-linux-gnu checking host system type... mips64el-unknown-linux-gnu checking target system type... mips64el-unknown-linux-gnu HOST: mips64el-unknown-linux-gnu GHC build : i386-unknown-linux GHC host : mips-unknown-linux GHC target : mips-unknown-linux configure: Building in-tree ghc-pwd ghc: unrecognised flags: -no-user- Usage: For basic information, try the `--help' option. configure: error: Building ghc-pwd failed /ghc-7.6.1$ grep "no-user" ./* ./aclocal.m4: if !

I can't find any information about this option. Thank you. PS: I only use free software (as defined by the FSF). Can I be sure that I won't install any non-free programs during the process?
