Hi,
I usually just copy those .a files (that should be linked statically)
into `ghc --print-libdir`.

The typical trick to force GHC to statically link a C library
is to give the full path to the .a of it as one of the object
files in the GHC invocation that does the final linking. This
means you don't need any -l or -L flags pertaining to that
library. Some libraries are very particular about the order
you list them in when doing this, but I don't really
understand the issues there. You usually will also have to
chase dependencies by hand and list them in the same fashion.
I recently tried using this method to create static binary; but
I was not able to get it to work. I thought I would revive this
old thread and see if anyone else has given it a shot.
What I attempted was building a binary with only some C libraries
statically linked, with this command line:
# Build https://github.com/erudify/sssp on Ubunut 12.04
ghc -outputdir ./tmp -v --make -O2 sssp.hs -o sssp.ubuntu \
/usr/lib/x86_64-linux-gnu/libffi.a \
/usr/lib/x86_64-linux-gnu/libgmp.a \
/usr/lib/x86_64-linux-gnu/libz.a
However, this really made no difference. Running `ldd' on the
resulting binary reveals that libz and friends are still
dynamically linked:
ldd sssp.ubuntu
linux-vdso.so.1 => (0x00007fff94253000)
libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f0ddfdbb000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
(0x00007f0ddfb9e000)
libgmp.so.10 => /usr/lib/x86_64-linux-gnu/libgmp.so.10
(0x00007f0ddf92f000)
libffi.so.6 => /usr/lib/x86_64-linux-gnu/libffi.so.6
(0x00007f0ddf727000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f0ddf42d000)
librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f0ddf224000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f0ddf020000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f0ddec63000)
/lib64/ld-linux-x86-64.so.2 (0x00007f0ddffdb000)
There is always -optl-static which, nowadays, results in a
truly static executable; but it leads to a lot of warnings, too.
