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

问题

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.

回答1:

There's no such type as uint long long.

There is long long and unsigned long long.

Qt also provides qlonglong.
