For compiling within Xcode 2.4 on Tiger, there should only be one copy of gnumake – the one in /usr/bin. If you are in fact using a Makefile, this implies you’re using the external build function of Xcode, since Xcode itself has its own build system. In this case, check your Project’s Target(s) and overall Project configuration, and make sure it specifies the appropriate custom-compile script.

If you are compiling on the command-line, check your path and make sure the make being picked up is the new make you installed. “which make” should show you the path being picked up, and “make –version” should show you the version used.

For Xcode 3.0 on Leopard, there’s another copy of gnumake in /Developer/usr/bin, which is used by the dev tools. But Leopard should ship with GNU Make 3.81, so your particular problem in that case might be elsewhere.

Simply replacing /usr/bin/make doesn’t seem to have fixed my malloc crash.

Thanks for the help!
