Loading package integer-gmp ... <command line>: can't load .so/.DLL for: libgmp.so (libgmp.so: cannot open shared object file: No such file or directory)

[Gergely Risko]

Hi,

Interesting.  You're already using the libraries/integer-gmp_CONFIGURE_OPTS
magic that I wanted to advise.

I think you should record the configure and build output, so it's easy
to look around in it afterwards (and don't use -j for make, because then
the output is mixed).  I would look for gmp relevant bits in that, to
see if it found it alright.  You can also try --with-intree-gmp (or
something like that) to force a statically linked intree gmp, that will
just work.

Also, I think "inplace/bin/ghc-stage2 --interactive" will fail with the
same error message, and you can "strace -f -e file" that command to see
where the libgmp.so is searched for. It should definitely be searched
for in your /nix/store/qnky...  directory with your build.mk.  I use the
same strategy here:
https://github.com/nilcons/ceh/blob/master/README.compile-ghc-with-ceh

If you just want to quickly try something and not really interested in
figuring out what's wrong, then a quick and dirty fix is to
"export LD_LIBRARY_PATH=/nix/store/qnkyas42nf0knps3va30y29y3zvmgy2v-gmp-5.1.3/lib"
before the whole build or anytime afterwards when you want to use the
compiled GHC.

But I'd really like to understand what caused it, so if you have time,
please investigate!

Gergely
