6.12.1 Release Candidate: profiling and libHSffi_p.a

[Neil Brown]

Hi,

I tried profiling a program with the GHC 6.12 release candidate.  I got 
this:

$ ghc -O1 -prof -auto-all --make CommsTime.hs
[1 of 1] Compiling Main             ( CommsTime.hs, CommsTime.o )
Linking CommsTime ...
/usr/bin/ld: cannot find -lHSffi_p
collect2: ld returned 1 exit status

Googling turned up this link, which suggests this problem was fixed 
earlier this year:

However:

$ find ~ -iname "libHSffi*"
/home/nccb2/lib/ghc-6.12.0.20091010/libHSffi.a
/home/nccb2/lib/ghc-6.12.0.20091010/libHSffi-ghc6.12.0.20091010.so
/home/nccb2/ghc-6.11.20090915/libffi/libHSffi.a
/home/nccb2/ghc-6.11.20090915/libffi/libHSffi-ghc6.11.20090915.so
/home/nccb2/ghc-6.12.0.20091010/libffi/libHSffi-ghc6.12.0.20091010.so
/home/nccb2/ghc-6.12.0.20091010/libffi/libHSffi.a
/home/nccb2/ghc-6.12.0.20091010/libffi/libHSffi_p.a

This seems to indicate that the library is built 
(/home/nccb2/ghc-6.12.0.20091010 is where I built GHC) but not installed 
on my system.  This is a Debian 32-bit system, and I don't remember 
passing any options to the GHC configure command besides --prefix.

Neil.
