Bug description

(This is for cygwin with ocaml 3.09.3)

I have a large project that I am trying to wrap inside a package. I use the
"-for-pack LibKettle" option on all compilations and "-pack -o libKettle.cmx" when linking.

If I look at the tmp/camlpackagexxx.s file I see lines like this:
movl $_camlConfig_base, _camlLibKettle
movl $_camlPretty, _camlLibKettle + 4
movl $_camlInthash, _camlLibKettle + 8
movl $_camlIntmap, _camlLibKettle + 12

The labels should be _camlLibKettle__Config_base, _camlLibKettle__Pretty, etc (should be translated in the new scope). This eventually results in undefined symbols when linking.

I have tried to reproduce the problem in a simple project, and I could not (I get the correct behavior there).

Any ideas how to make progress debugging this?

George Necula.

You should check that enough -I options are given (when -pack'ing) so that all the .cmx files can be found (even if you give their full path on the command line).

This requirement should really be fixed or documented!

Thanks Alain, that was indeed the problem. But PLEASE add a sentence to the documentation. It would have saved me a couple of hours of work.

Improved handling of .cmx during ocamlopt -pack. The .cmx given on the command line are now honored even if they cannot be found in the search path.
Also, added better link-time reporting of other corner cases involving -for-pack
and missing .cmx files.
