ghci does not consider library-dirs of dependent packages for dlopen()
On OSX, when ghci loads a package (eg ghci -package gtk
) it uses dlopen on the .dynlib files specified in the package registration. However it appears to look only in the library-dirs
of the package itself and not of the dependent packages.
This shows up with gtk2hs on OSX when the glib and gtk C libs are in a non-standard location (/opt/local/lib). The glib package registration file uses library-dirs: /opt/local/lib
and the gtk package depend on the glib package. The gtk package requires the C lib libgthread-2.0.dynlib. This exists in /opt/local/lib
however when loading the gtk package in ghci, it does not look in /opt/local/lib
. It only does so if we modify the gtk registration file to specify library-dirs: /opt/local/lib
.
This behaviour of not using the lib dirs of dependent packages is inconsistent with the static linking case. I suspect this bad behaviour is specific to OSX, because I think this has always worked in the gtk2hs windows installers.
