This sounds like missing dependencies in your package configuration file. Most package mention e.g. at least the "base" package:

package_deps = [ "base" ]

Looking at the undefined references will probably help to figure out what should be mentioned in your case. You don't have to do this transitively, BTW, GHC(i) is cunning enough to do this itself, e.g. the "base" package depends on the "rts" package, but you don't have to specify this in your configuration file.

In fact I hadn't defined the dependencies. The package needs the TclHaskell package and this one needs lang which needs base. The conf file for my package now is as follows: Package {name = "CHD", auto = False, import_dirs = ["/usr/local/lib/ghc-6.2.1/hslibs-imports"], source_dirs = [], library_dirs = ["/usr/local/lib/ghc-6.2.1"], hs_libraries = ["HSCHD"], extra_libraries = [], include_dirs = [], c_includes = [], package_deps = ["TclHaskell"], extra_ghc_opts = [], extra_cc_opts = [], extra_ld_opts = [], framework_dirs = [], extra_frameworks = [] } Sadly defining the dependencies didn't solve the problem.

All these undefined references ("zi" => ".") seem to be within your own package "CHD", but guessing what goes wrong exactly is a bit hard without further information. A complete log of what you are doing might help, a tar file including your sources would be even better (when building is as simple as "make" or the like). This is a general hint for people reporting non-trivial problems: Whenever possible, package up everything necessary for reproducing the problem in a way that a plain "make" suffices, and attach it to your problem report. Remember: This is a "lazy" mailing list... :-)

Here is the sourcecode and the Makefile I use. Just decompress the file and adjust LIBDIR and IMPORTS in the Makefile. "make" compiles the sources, "make install" copies the library and the interface files to the directories defined in LIBDIR and IMPORTS. A "make pkg" creates a CHD.conf and adds it to the package.conf by using ghc-pkg. A "make uninstall" and "make unpkg" removes all files and restores the original state, I hope. In the Test directory is a sourcefile called PhilsCHD.hs which uses the CHD package. A "ghc --make -package CHD PhilsCHD.hs -o PhilsCHD" causes the linking errors. Gruss Jan
