Hello, The way I've organized files in CVS may be a little weird. I wanted to keep CL-Carbon separate from anything that may use it like Example. Here is a simple step by step 'script' that should allow you to build a working application bundle from the CVS sources provided you have OpenMCL properly installed with the interfaced databases. I'm assuming ~/usr/src/ which is where I like to keep my projects. cd ~/usr/src cvs -d :pserver:anonymous@common-lisp.net:/project/cl-carbon/cvsroot login cvs -z3 -d :pserver:anonymous@common-lisp.net:/project/cl-carbon/cvsroot co Example cd Example/lib cvs -z3 -d :pserver:anonymous@common-lisp.net:/project/cl-carbon/cvsroot co CL-Carbon cd .. ln -s lib/CL-Carbon/cl-carbon.asd cl-carbon.asd sh make.sh This should result in a working Example.app in the bin directory. I've not included swank in Example. I recomend setting up another project for that. OpenGL Demo on my personal website shows how swank is used so that you can use Emacs + Slime to connect to the running application. It may be a good idea to make the build system part of CL-Carbon. That's the way Bosco handles it.
