Hi, It seems that with GHC 6.2, -keep-hc-files and --make conflict: GHC deletes the HC files it makes. I found an old bug report about this, with a note from one of the developers claiming to have fixed this, but at least here the bug is reproduceable (a regression, perhaps?). This is on up-to-date Debian unstable. -- Antti-Juhani Kaijanaho, FM (MSc), http://www.mit.jyu.fi/antkaij/ ohjelmistotekniikan assistentti * assistant in software engineering Jyväskylän yliopisto * University of Jyväskylä Tietotekniikan laitos * Dept. of Mathematical Inf.
