Do you need to use the full path for executing g++? This makes me think
that z:/MSYS2/mingw64/bin is not in the PATH. Make sure that you execute
bash using the correct shortcut. Alternatively, in bash do this:
export PATH=/z/msys2/mingw64/bin:$PATH
g++ -o Helloworld Helloworld.cpp
./HelloWorld
If the above works, your problem is with PATH environment variable. g++
produces executables that depend on some DLLs, if those DLLs are not on
a directory listed on PATH or in the same executable where the
executable is, the execution will fail. Also, if other dll with the same
name is in some directory listed on PATH, the program may crash.
BTW, it is not x64, it's either x86 (32 bits) or x86_64 (64 bits). Also,
do not confuse MSYS2 executables with Mingw executables. The former
depend on a POSIX emulation system (provided by msys-2.0.dll).
