Cross-building GHC

[Nikita Karetnikov]

I'm trying to cross-build the Glasgow Haskell Compiler 7.6.2 [1].

I got stuck when I was trying to build a cross-compiler (Stage 1).
For some reason, it uses '/usr/bin/ld' instead of a cross-linker.

Could anyone try to reproduce the problem?

The process is described here [2].  If I got it right, you have to run

# ./configure && make && make install && make clean

twice (Stage 0 and libs boot phases).  Then you should be able to
build the Stage 1 compiler:

# ./configure --target=mips64el-linux \
              
--with-gcc=/nix/store/khdyz3i5aih56lxfk6hjvp3884apm7qb-gcc-cross-mips64el-linux-gnu-4.7.2/bin/mips64el-linux-gnu-gcc
 \
              
--with-ld=/nix/store/bqw0chxysv4x73mf6bv7jqmgy7553xqh-binutils-cross-mips64el-linux-gnu-2.22/bin/mips64el-linux-gnu-ld
 \
              
--with-nm=/nix/store/khdyz3i5aih56lxfk6hjvp3884apm7qb-gcc-cross-mips64el-linux-gnu-4.7.2/bin/mips64el-linux-gnu-gcc-nm

However, the above doesn't work.  I'm getting the following error:

/usr/bin/ld: 
/nix/store/mifp2p1zjlvb4ndslw1r8grkpglybqjf-glibc-cross-mips64el-linux-gnu-2.17/include/../lib/crt1.o:

The GCC-related configuration, which works for a "hello world" program,
can be found here [3].  The only difference is that I used

# export 
LIBRARY_PATH=/nix/store/mifp2p1zjlvb4ndslw1r8grkpglybqjf-glibc-cross-mips64el-linux-gnu-2.17/include

instead of C_LIBRARY_PATH.
