I'm experimenting with Code::Blocks with the idea of using it for Raspberry Pi development, and I thought I'd try it out on my Mac first. Since the current version doesn't work well on the Mac I thought I'd give some running commentary on my progress.
1. Starting with the linux build instructions.
2. Installed autoconf and automake using Homebrew
3. Since wxWidgets isn't installed system-wide, the aclocal path had to be updated -- the wxWidgets .m4 file is in the root of the wxWidgets directory.
4. Code::Blocks builds, installs to /usr/local, and runs without a hitch.
5a. No project templates. It looks like the Mac build expects plugins to be in ~/Library/Application Support/codeblocks/...
5b. Symlinked the Library 'plugins' folder to the one in /usr/local. Now I have project templates.
6. Made a simple "Hello World!" console project.
7. Code::Blocks runs clang, but generates no output and reports "GetCFStringRef, i is not the right type". On the plus side, it properly created the build directories.
And that's where I am so far. I'll post further developments as I work through problems.
