I am following the installation instructions from SWI-Prolog's site. I am on a Linux machine.
First I git-clone the repo and cd into swipl-devel.
Next I run the commands:
git submodule update --init
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX="${install_under}/swipl" -G Ninja ..
ninja
This all goes smoothly.
Next, when I run ctest -j 4 I get back:
98% tests passed, 1 tests failed out of 66
Total Test time (real) = 15.23 sec
The following tests FAILED:
24 - swipl:xsb/nonmt_tests (Failed)
Errors while running CTest
I then become root and run ninja install. Here is what I get back:
[12/13] Install the project...

I am not sure what I am missing.
There is something really going wrong.
I have never had the swipl:xsb/nonmt_tests tests failing (whatever they are).
Is the shell variable install_under properly set when you run the above?
For example, I always install under a directory like /usr/local/logic/swipl, so here you would have to say
-DCMAKE_INSTALL_PREFIX=/usr/local/logic/swipl
or
export install_under=/usr/local/logic/
in your case (not sure whether the export is needed, it sets an environment variable).
