Configuring Xcode for gcc 3.3.2?

Thursday, June 10 2004 @ 05:01 PM CEST

I need to compile a binary with the latest version of gcc 3.3.2 to get rid of specific compiler errors but Xcode only provides gcc 3.3.1. Now, I have downloaded and installed gcc 3.3.2 successfully but it hasn't overwritten the gcc 3.3.1 installation as the files are in a different path.

So, when I compile, Xcode is still using the old gcc 3.3.1 and I'm getting the same errors. I've tried changing the quick open paths, which referred to the old gcc 3.3.1 package but that hasn't helped. Are there some internal preferences that I need to change?

Can I use a Mach-O plugin with a CFM app?

I have been trying to build some CFM plugins for Maya, but before the latest version (v6), it was a CFM app. This means that the plugins it supports are CFM and the only way to make those is with Codewarrior as Xcode doesn't support CFM plugins.

Is there a way to perhaps make a bridge/interpreter between the CFM application and a Mach-O plugin? I know it's possible to get a CFM app to work with a Mach-O plugin but the CFM app has to be built to work that way. I was wondering if it could work by just modifying the Mach-O plugins somehow.

Use XCode for cross platform development

I want to use the XCode for cross platform development.
I.e. I want to compile m68k based targets using a cross compiler.
For now I got a Makefile based solution but I'd like to use "native" target to accomplish the same task.

Any idea how I could do this?

I have a problem linking my project to a dylib of my own: the dylib is correctly installed in the search path and I have the correct -lMyLib flag set in the linker option, but the linker always report an "Undefined symbol: xxx". What can be wrong?
