Errors during test

[atupone]

During test phase I got a lot of
ModuleNotFoundError: No module named 'liblktlang'

I cannot find from where this module come

[pmderodat]

Liblktlang is a Langkit sub-project that we are developping to switch from Langkit’s Python DSL to a dedicated syntax. We’ll update the README accordingly, thank you for bringing this to our attention. In the meantime, the procedure is simple:

# Build libpythonlang/liblktlang
./manage.py make

# Make them available to the environment
eval `./manage.py setenv`

# You can then run the testsuite

[atupone]

As reported in the closed pull request #614 there are problems for this tests:

testsuite/tests/langkit_support/*
testsuite/tests/adalog/*
testsuite/tests/misc/link_two_libs

those tests run gprbuild without -XLIBRARY_TYPE and so the build could fail if some libraries is built with both static and relocatable

[pmderodat]

As discussed in #614, this should not be a problem if the GNATCOLL dependencies are built and installed using the documented procedure: the installed projects should all correctly interpret the LIBRARY_TYPE variable. Can you clarify what you did and which error you get exactly?

[atupone]

On that file the gprbuild does not have -XLIBRARY_TYPE declaration, at least I am not seeing them.

For the one related to #614, you are right.

However I will try to test it again

To build I did the things that are in the link (I'm trying to provide it)

https://github.com/gentoo/gentoo/blob/master/dev-ada/langkit/langkit-22.0.0-r1.ebuild

and commenting out the rm part in prepare I am obtaining a lot of :

This is still the same issue, but with a different project:

gnatcoll.gpr:10:17: shared library project "gnatcoll" cannot import static library project "gpr"

Now you have to check how you install libgpr: make libgpr.build libgpr.install should be enough (https://github.com/AdaCore/gprbuild/blob/master/Makefile#L10). Just as before, you need to build and install all the variants (static, static-pic and relocatable). And then I suspect that you’ll have to check XML/Ada as well.

Hello,

Considering that this is most likely a setup issue (i.e. not a Langkit/testsuite bug), I’ll now close this issue. Please let us know if you still need help on this.
