Thread: want a .bat file to call the c compiler to compile and run c program

Is there any particular reason that you want to do this?

Anyway, assuming MinGW is in your path, something like this should work.

Code:

g++ program.cpp -o program.exe
program.exe

You might want to specify the paths to program.cpp or .exe, etc.

You can also compile multiple files this way, by specifying more than one .cpp file -- or you can only compile the .cpp files that need compiling . . . but you quickly lose track of which ones need recompiling and which ones do not.

If you start using multiple source files, use make. Even if you're only using one source file, a Makefile can make (sorry) your life a lot easier.

Here's a very simple makefile to compile program.cpp into program.exe.

Code:

program.exe: program.o
	g++ program.o -o program.exe

program.o: program.cpp
	g++ -c program.cpp

Save that as "Makefile", type make, and bam, away you go. (Or call it whatever and use make -f whatever.)

Note that you have to use tabs in Makefiles. Not spaces.

If you want to learn more, find a make tutorial. There are lots out there.

So what happens if the compilation fails?

Can you be more specific than "it doesn't work".
Does it for example complain about not being able to find gcc.
