(1) When I try to add a package to ghc, I receive the error message that a GHCi lib file cannot be found.

ghc-pkg -u -i fgl.pkg Reading package info from "fgl.pkg"done. Expanding embedded variables... done. warning: can't find GHCi lib `HSfgl.o' Saving old package config file... done. Writing new package config file... done.

The missing file `HSfgl.o' is located on the current directory as well as in the directory where all other .o and .a files for GHC are kept (/usr/local/lib/ghc-6.2/).

ghc-pkg is looking in the directories specified in the library_dirs field in fgl.pkg. HSfgl.o should be in one of those directories.

This has puzzled me for a long time as well. I /always/ get this warning message, even when the HSfoo.o file is in the correct place, as listed in library_dirs.

Strange. I just tried a simple example, and didn't get the warning, so at least it's not completely broken. Can someone who is getting this warning send me: the package config being fed into ghc-pkg, and an ls -l of each directory in library_dirs. Cheers, Simon
