This is a large list of common problems and solutions, mostly error messages, related to software, C++, Linux, Python and all other - especially error messages so we can easily search them (or that search engines can find them if it's a new one)
C++,Build,CMake Q: Strange errors during compilation form gcc run by make after running cmake about not existing options, that look like several options lumped together. e.g. something like g++-8.3: error: unrecognized command line option ‘-fPIE -Wnoexcept -Wstrict-null-sentinel -Wlogical-op -mmitigate-rop’ A: This is fixed by putting all related compilation flags in quotes in the CMakeList file. Example of fixing: commit ce1db84ca386add849cb128aa14f32c855292edf in VoteCastle
