Test failure and warning in last SWI build

General
1

I’ve just updated swi pulling from github. During the build process i get a warning (maybe harmless)

/swipl-devel/src/pl-gmp.c:1543:7: warning: ‘r_mode’ may be used uninitialized in this function [-Wmaybe-uninitialized]
       fesetround(r_mode);

Moreover, the SSL test fails again (i know about this issue that has been solved, but now the problem is still present). I’m using WSL on Windows 10. Running

$> swipl --version

i get

SWI-Prolog version 8.3.1 for x86_64-linux

If you check the source you see this is a false alarm. So far the compilers I’ve used understand there is no problem. Just ignore.

If you just did a pull and rebuild from a location where you build before, start with

rm -r packages/ssl/tests
ninja
ctest -R ssl

If that still fails, run this to see the output of the tests, so we may have some clue.

ctest -V -R ssl

After removing packages/ssl/test, the ninja command prints an error:

ninja: error: loading 'build.ninja': No such file or directory

Maybe because i’ve built SWI using make?

Ok, i’ve downloaded it and rebuilt again. The error is no more present

Yip. Run make instead of ninja

Normal update:

git pull
git submodule update
# check that everything is cleanly updated:
git status

Now build, assuming you build in a subdir build

cd build
ninja    # or make, depending on how you ran `cmake`
ctest -j 8  # concurrent test.  Number of cores, more than 16 is useless.
ninja install

If ssl test fails due to expired test certificates:

rm -r packages/ssl/tests
ninja
ctest -R ssl

Build also tends to fail after an OS upgrade or an upgrade of dependencies (notably ssl). In that case remove the entire build subdir and recreate it.
