#7717: Libffi errors while cross-compiling GHC 7.6.2 (Stage 1) -----------------------------+---------------------------------------------- Reporter: guest | Owner: Type: bug | Status: new Priority: normal | Component: Compiler (FFI) Version: 7.6.2 | Keywords: Os: Unknown/Multiple | Architecture: mips Failure: None/Unknown | Blockedby: Blocking: | Related: -----------------------------+---------------------------------------------- I'm trying to cross-build GHC 7.6.2. I got stuck when I was trying to build a Stage 1 compiler [1]. (There is a chance that it's not a bug; maybe I misunderstood the process.) Steps to reproduce: $ ./configure --target=mips64el-linux --with-gcc=/usr/bin/gcc \ --with-ld=/usr/bin/ld --with-nm=/usr/bin/nm Did I specify the wrong binaries? These are the same I used for Stage 0 and libs boot phases. Maybe I should use the ones for mips64el... But how? ---------------------------------------------------------------------- Configure completed successfully.
