Cannot run the Docker app on macOS

[cklamra]

I haven't been able to run the app on macOS 10.15. Running docker-compose build would result in following errors:

#75 86.97 c++: internal compiler error: Killed (program cc1plus)
#75 86.97 Please submit a full bug report,
#75 86.97 with preprocessed source if appropriate.
#75 86.97 See <file:///usr/share/doc/gcc-5/README.Bugs> for instructions.
#75 87.26 libwccl/CMakeFiles/wccl.dir/build.make:2070: recipe for target 'libwccl/CMakeFiles/wccl.dir/variables.cpp.o' failed
#75 87.26 make[2]: *** [libwccl/CMakeFiles/wccl.dir/variables.cpp.o] Error 4

This was probably caused by running out of memory (Docker on Mac also runs a Linux VM). Assigning 16 GB of RAM to Docker wouldn't solve the problem; I have managed to build the app after changing make -j to make -j1 in the Dockerfile.

There was another problem - running python3 stuff/python/liner2rmq.py -t "Pani Ala Nowak mieszkw w Zielonej Górze" would result in:

[INFO] Temp route: route-XAYR69
[INFO] Temp input file: /var/folders/dz/7xrvhr2s43j71_k_f2zch2fw0000gn/T/hl833qwm

Logs on the server side:

liner2_1    |  INFO [pool-1-thread-4] (RabbitMqWorker.java:105) - Received path: '/var/folders/dz/7xrvhr2s43j71_k_f2zch2fw0000gn/T/c5tl6vhc'
liner2_1    | ERROR [pool-1-thread-4] (RabbitMqWorker.java:81) - An exception occured
liner2_1    | java.io.FileNotFoundException: /var/folders/dz/7xrvhr2s43j71_k_f2zch2fw0000gn/T/c5tl6vhc (No such file or directory)

stuff/python/liner2rmq.py uses the OS default temp dir, which in case of macOS is not /tmp. In my case running echo $TMPDIR yields
/var/folders/dz/7xrvhr2s43j71_k_f2zch2fw0000gn/T/.

I have changed tempfile._get_default_tempdir() in liner2rmq.py (line 37) to '\tmp', which solved the problem.
Mounting the default temp directory to a volume also worked.
