cmake can't find cxxtest about opencog HOT 13 CLOSED

If I remember right, there are two versions of cxxtest: the one we use, and
a newer one which is not compatible with it. I'm guessing you installed
the new, incompatible one.

The cxxtestgen executable is in /usr/bin, so I tried

CXXTEST_BIN_DIR=/usr/bin/ cmake ..

and got the same result.

The latest release is 4.0.3.

OSX: installed after downloading from github. No errors from cmake.

Debian Linux: installed the Debian package. Cmake can't find it. Removed the package and installed from the
github source. Cmake still can't find it whether CXXTEST_BIN_DIR is set or not.

opencog requires cxxtest version 3 and not version 4. The problem is that version 4 is not backwards-compatible with version 3, and no one has yet figured out how hard or easy it might be to move opencog to use cxxtest version 4. This would be an excellent beginner get-your-feet-wet project.

I found the problem and worked out a fix for it. It works for Debian, but I want to try it out on OS X next and then clean it up. I'll submit the pull request later this week.

What's the fix? small? big?

BTW, its OK to push to your private branch now, for review; just don't
issue a pull request, and it won't get merged until you are ready (i.e.
until you check in the remainings OSX pieces)

Here's the diff for a quick-and-dirty fix:

$ diff lib/FindCxxtest.cmake lib/FindCxxtest.cmake.orig

< FIND_PATH(CXXTEST_PYTHON_BIN_DIR cxxtestgen

> FIND_PATH(CXXTEST_PYTHON_BIN_DIR cxxtestgen.py

<       SET(CXXTEST_GEN "${CXXTEST_PYTHON_BIN_DIR}/cxxtestgen")
---
>       SET(CXXTEST_GEN "${CXXTEST_PYTHON_BIN_DIR}/cxxtestgen.py")

I guessing that since the earlier CxxTest release the Perl script was dropped and
the Python script was renamed 'cxxtestgen'.

I've since found that CxxTest has no installation scripts and I think the files have to
be installed manually. The changes I made to FindCxxtest.cmake are enough to
work under Debian Linux because the Debianized CxxTest package puts everything
where OpenCog can find it. So my fix and the Debian package should also work
under Ubuntu.

Great! I noticed that cxxtest 4.0.3 is packaged for Ubuntu 12.10 when I did
some early quantal testing.

http://packages.ubuntu.com/quantal/cxxtest

Did they make the same fixes as yours?

And after these changes, do the unit tests compile and mostly pass? Years
ago, when I last tried it, I got the impression that cxxtest 4.0 just
wasn't backward compatible with 3.0, and that we'd need a major revamp to
be able to use it.

anyway, I just merged a fix to the FindCxxtest.cmake file that should at least find the thing.

I've got cxxtest 4.0.3 installed and I'm getting the following errors

Nevermind, this comes from another bug I'm trying to fix. When cmake is rerun then CXXTEST_GEN is set to cxxtestgen.py. I've fixed it and will commit it soon.

Hmm. I thought the new CMakefiles should have worked, although you'd
probably have to remove CMakeChache.txt to get a clean build with no cached
grunge left over.
