I use C::B with a "custom makefile". Actually I use SCons rather than make, however in this version of C::B it seems to completely ignore the "Make" commands that I have specified. In other words it always gives me grief about their not being a Makefile, or there is nothing to do in the Makefile. I noticed there was some changes related to this area in this release, so I was wondering if something got broke somehow. An easy way to test would be to simply setup a project as a custom makefile project and change your build lines to execute a helloworld script or something and see that output come out in the BuildLog tab.
