minGW CPP G++ Proper Command to Compile

I installed the following: MINGW32_NT-6.1 i686 Msys

I am working with the command line. Wrote the "typical" HelloWorld.cpp program.

IF I compile with: cpp HelloWorld.cpp -o HelloWorld.exe COMPILE is good. (18k) BUT execution fails: 16 bit MS-DOS Subsystem. NTVDM CPU error

IF I compile with: g++ HelloWorld.cpp -o HelloWorld.exe COMPILE is good. (48k) Execution is good.

I cannot determine the BEST way to execute the compile and what the difference is between the methods. Any suggestions? or good references? THANKS.

"cpp" is the "C PreProcessor", not the compiler. So you're just getting something strange in HelloWorld.exe

Execute the "type HelloWorld.exe" and see what it gives. It shouldn't even be a binary file - just a long text file with all the "#includes" and "#defines" replaced.

To your question - the second way is "right", because you actually invoke the compiler/linker and produce a valid executable. The first "way" is a valid command, but it has almost nothing to do with compilation and linking.
