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:
http://www.mail-archive.com/cvs-...@haskell.org/msg13546.html
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.
