Actually in my understand, Qt need:
1) POSIX compliant base (pthreads? mmap? fork?)
I can disable parts individually or need some kind of #ifdef sparse by the
code? I see some kind of preprocessor magic scattered in the code like
this:
https://github.com/qt/qtbase/blob/4b0af2cdbf61572b22ea6b8aa17fc9f52c71ac4b/
src/corelib/thread/qthread.cpp#L174
Yes, POSIX compliant base including pthreads and filesystem API. What the
filesystem API accesses is irrelevant, it just has to exist. Threading support
is mandatory in Qt, even though there are #ifndef QT_NO_THREAD around. Those
aren't tested and aren't guaranteed to even compile. You can try that at
first, but I recommend aiming for full threading.
Actually, QtWebAssembly platform is a supported platform and default is
nothread. :) What is not tested is nothread on a different platform like
desktop.
