Missing deps on test sections?

[pveber]

Hi,
starting from a fresh install, I fail to install oasis:

philippe@robby:~$ echo $OCAMLPATH
/home/philippe/.odb/lib
philippe@robby:~$ rm -rf ./.odb
philippe@robby:~$ ocaml odb.ml oasis

It seems that odb do not add deps from the test section (fileutils and oUnit), while the configure script of odn requires them. This issue is related to #25, in that there is a need to access test dependencies with oasis-db.

Easy workaround of course, first install the missing dependencies, by invoking ocaml odb.ml fileutils directly. I'm posting it here for the record (hope I'm not duplicating a previous bug report ...)

Sadly, this is a known and undocumented problem. The problem is just in the ocaml-data-notation package. Gildor patched 0.0.6 quickly, and must have used his development version of oasis to generate its setup.ml file. This file tries to configure dependencies needed for testing, and fails because it can't find them. Oasis-db only lists as dependencies those packages needed to build and install, not to test. There's two solutions, the short-term fix-odn solution and the long term fix-oasis-db solution. I'm trying for the long term solution, but need gildor's help.

[pveber]

To be honest, I think it is better in every way to fix odn: a package shouldn't be released in setup-dev mode. Maybe I can simply reupload a fixed odn on oasis-db?

[gildor478]

The package had been released in setup-dev mode. It seems there is a bug with deps computation when there is a flag involved. Consider filling a bug to remind me to solve this.

[pveber]

Thanks for commenting on this Sylvain. If I understand you right, the lib part of oasis, which is used to compute dependencies, is at fault here. That would mean that the REST API needs no change, it should just provide enough dependencies for the package to compile, even if the package is in setup-dev mode, right?. Anyway I'll gladly report this on the bug tracker of oasis.

[gildor478]

OK, I totally mismatch my sentence. "The package had NOT been released in setup-dev mode". The rest of the comment stands. There is a bug in dependency calculation with flags. Please fill a bug against oasis. The quick solution is to have "Default: false" for flag Test in odn.

Bug reported, thanks!
