pip install pyqt5 --config-settings --confirm-license= -vvv on OFW Samsung Galaxy S7 Android 8 and it runs until printing this messageps -ef shows it is using clang++ to compile C++ code in the background. It looks like -j1 already because it looks like only one instance of clang++ runs at a time.htop it looks like "Mem" remains about 2.2G/3.64G used while "Swp" gradually fills up to 1.99G/2.00G, then, after about 3 hours, the command fails with this error:pip prints a lot of python related information but does not show any output of clang++ or linker, so I cannot see the real error.--max-load 1 into the make invocation of pip somehow to see if that might help?
