Mere import chasing and linking is fairly fast (regardless of Solaris-ld
or GNU-ld)

But last night my ghc-6.6 job hung around for about 2 hours but continued.

I have often seen problems like this with the Solaris linker. (I suspect it must have a super-linear algorithm for resolving symbol references.) It's not a linker problem, ghc-6.6 hangs on other occasions, too. I've tried both linkers, they link with the same speed nowadays.

After compiling 643 modules (in 5 minutes) ghc-6.6 did not finish it's
batch job. (I've killed the job then next morning.) This happened on a PC
(i386-solaris2.10).

I think, I've seen the same happening several times under sparc-solaris. I
don't know how to reproduce this.

Maybe the ghc pipeline driver needs to be taught how to do that? this information is probably out of date by now, but there used to be several bug reports pending for the Solaris linker, of the kind order of magnitude worse than gnu. there also were repeated attempts to fix this in patches, so perhaps this is not the same problem anymore. but you might want to give GNU ld a try, just in case: http://haskell.org/haskellwiki/GHC/FAQ#Why_does_linking_take_so_long.3F something like: GCC_EXEC_PREFIX=path-to-binutils ghc other-options if those Solaris linker issues have been fixed, you might want to update the GHC Faq (I'm not using Solaris at the moment). if those linker issues are still around, and the GNU binutils workaround still saves the day, perhaps that FAQ entry ought to be linked from GHC on Solaris section as well? hth, claus ___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
