The profiled version of the latest Edison library doesn't work for me.
I got Edison 1.2 via darcs. I used the regular 'make system'
command to
build and install the regular (non-profiled) version of Edison. Then I
went to edison-api and edison-core subdirectories, in turn, and
executed
the Cabal commands:
runhaskell Setup.hs clean
runhaskell Setup.hs configure --enable-library-profiling
runhaskell Setup.hs build
runhaskell Setup.hs install
The library seems to be properly installed:

I compile the profile version of my program using the following line:
ghc -package text -package EdisonAPI -fglasgow-exts --make Main -o
gens-prof -odir profiler -hidir profiler -prof -auto-all
The ghc version is 6.4.2, by the way. When I run the compiled program,
it keeps grabbing memory until it's killed by the system.
Enabling profiling can significantly change the space behavior of
programs. There may be some important optimizations that don't occur
in the presence of profiling, and the profiling data itself takes
some memory. I have to admit, I don't know a lot about GHC profiling
so I'm afraid I can't be of much help. If you can scale down the
problem size to do your profiling, that may keep it from being OOM'd
and let you get some useful data.
The
non-profiled version of the program runs perfectly well. In fact, the
PatriciaLoMap from Edison seems to be about two to three times faster
than Data.Map library for my purposes.
That's good to hear. What's the usage pattern?
Lots of unions. So you might say
that I don't need profiling any more, but still...
Any ideas on what might have gone wrong?
