compiling gpsim on macOS causes "error: 'long long type-name' is invalid"

Question

Following this question, I'm trying to compile this code on macOS. I ran

/System/Volumes/Data/usr/local/Cellar/qt/5.14.1/bin/qmake

inside the build_XX folder successfully, and then make. However, I get the compiling error:

../src/gpsim/protocol.cc:79:8: error: 'long long type-name' is invalid
  uint long long i = ascii2uint64(buffer, digits);
       ^
1 error generated.
make: *** [build/release/protocol.o] Error 1

as suggested here, I added

#ifdef __APPLE__
#include <sys/types.h>
#endif // __APPLE__

at the top of the protocol.cc file with no avail. I would appreciate it if you could help me understand what is the problem and how I can solve it. Thanks for your support in advance.

There's no such type as uint long long.

There is long long and unsigned long long.

Qt also provides qlonglong.

so this is a bug, with any other compiler as well? and has nothing to do with macOS or clang for that matter?

OP mentioned Qt. Qt does in fact provide uint. Hence, I'm a bit puzzled why uint long long shouldn't work. Of course, I didn't dig deeper. A missing Qt header might explain...

@Foad As far as I know, yes.

it worked, but I will be waiting for @JesperJuhl to see why Qt doesn't work properly here.

@Foad Too funny that I noticed two last commits in the linked github repo with something like "long long fixed" which appeared just 13 minutes (!) before you sent your question... ;-)
