test_widelands_scripting compilation fails

[Nasenbaer]

Error during compilation of the test script on Opensuse 11.3 and Opensuse 11.1:

Of course Widelands is already compiled at that point, but most of the users do not notice it.

Which revision did you use and did you explicitly requests tests to be built?

After r5564 tests should not be built by default. If tests are selected for building, there will be helpful message in generation step if unit test library is missing. At least fresh 32-bit ubuntu 10.4 did not try to compile unit tests after checkout and ./compile.sh. If you are using older checkout and did not cleanup cmake files, then there may be a cached flag that enables building unit tests. You can check this out for example by running cmake -i and observing what's value for BUILD_UNIT_TESTS variable.

Anyway, I'll download and install opensuse 10.3 x64 and test it.

[Jari Hautio (jarih)]

I could not reproduce using opensuse 11.3 x64 and current trunk r5584.
I had to install tiff and jpg development packages in addition to what's stated on the BuildinWidelands wiki page.

[Jari Hautio (jarih)]

Now I could reproduce it. I forgot to enable test building. Opensuse does not ship static libs and CMake automatically picked shared version. This in turn would require another flag when building unit tests.

I'll make a fix.

[Jari Hautio (jarih)]

Fixed in trunk r5588. Switched to dynamic unit test framework outside windows platform. Tested on opensuse 11.3 (x64), OS X 10.6, ubuntu 10.4 (x86), windows/MSVC2008.

[David Allwicher (aber)]

Why did you disable static linking for the unix like platforms?

[Jari Hautio (jarih)]

Static boost libs were not found on opensuse 11.3. Dynamic libs are found always. Besides everything else is normally dynamically linked on non windows platforms anyway. On windows static linking is better because then there's no need to copy the dll's or ensure that dll's are found in path.
