Building GHC on Mac stops

[Nicolas Frisby]

I never determined how to fix this. Here's the notes I developed:

tl;dr For some reason, it seems gmp.h is not recognized as a dependency of
mkGmpDerivedConstants.o

HTH

-----

If I run

$ perl boot; ./configure; make -j4

I tend to see a build failure. Immediately running make -j4 again succeeds.

In the following snippet from the log,
FILE=libraries/integer-gmp/mkGmpDerivedConstants/mkGmpDerivedConstants.c

{{{
"/usr/bin/gcc"  -m64 -fno-stack-protector
  -Ilibraries/integer-gmp/gmp
-Ilibraries/integer-gmp/mkGmpDerivedConstants/dist
  -c FILE -o
libraries/integer-gmp/mkGmpDerivedConstants/dist/build/mkGmpDerivedConstants.o

FILE:15:17: error: gmp.h: No such file or directory
FILE: In function ‘main’:
FILE:68: error: ‘MP_INT’ undeclared (first use in this function)
FILE:68: error: (Each undeclared identifier is reported only once
FILE:68: error: for each function it appears in.)
FILE:69: error: expected expression before ‘)’ token
FILE:69: error: expected expression before ‘)’ token
FILE:70: error: expected expression before ‘)’ token

make[1]: ***
[libraries/integer-gmp/mkGmpDerivedConstants/dist/build/mkGmpDerivedConstants.o]
Error 1
make[1]: *** Waiting for unfinished jobs....
}}}

Some 1677 lines later, I see the line

> cp libraries/integer-gmp/gmp/gmpbuild/gmp.h libraries/integer-gmp/gmp/

Which is I suppose why make -j4 succeeds the second time around.

I also see

> libraries/integer-gmp/mkGmpDerivedConstants/ghc.mk:20:
libraries/integer-gmp/mkGmpDerivedConstants/dist/build/.depend.c_asm: No
such file or directory

many lines above.
