Thread: Can't change global variable :(

I run sh build.sh which contains this:

Code:

prep_gcc() {
	if [ "$1" = "64" ]; then
		ARCH=amd64
	elif [ "$1" = "32" ]; then
		ARCH=i386
	fi
	if [ "$2" = "mgw" ]; then
		_FLAGS=$mWall $mWerror $mmconsole $mmwindows $mmwin32
		if [ "$1" = "64" ]; then
			PFX=x86_64-w64-mingw32-
			LFLAGS=-m64
			CFLAGS=-m64
		elif [ "$1" = "32" ]; then
			PFX=i386-w64-mingw32-
			LFLAGS=-m32
			CFLAGS=-m32
		fi
	fi
	LD=$PFXgcc
	CC=$PFXgcc
	CXX=$PFXg++
	LFLAGS=$_FLAGS $LFLAGS
	CFLAGS=$_FLAGS $CFLAGS
	O_DIR=$PFXgcc
}
prep_gcc 64

Shortly after the start, but when trying to append O_DIR I find that it is empty resulting in a path like this

Code:

objs//lu.c.o

ah that's where I slipped up thx
