{{{
C:\Temp>type Main.hs
main = print "neil"
C:\Temp>ghc --make -prof -auto-all Main.hs
[1 of 1] Compiling Main ( Main.hs, Main.o )
Linking Main.exe ...
C:\Temp>main +RTS -hc
"neil"
C:\Temp>hp2ps main
hp2ps: cannot open main.exe.hp
}}}
This can be fixed by either renaming the generated main.hp to main.exe.hp,
or running "main.exe +RTS -hc" in the first place. I guess you are using
argv [0]as the basis of where to put the heap profiling information, and
using the executable name as the basis of where to find it.
My suggestion would be that heap profiling information should always go at
basename.hp (so main.hp), ignoring any extension. This would require
fixing up both the RTS and the hp2ps utility.
