FAIL: libIDL on Mac OS X 10.6 (Snow Leopard)

Since I upgraded my laptop to Snow Leopard, I’ve been trying to setup my development environment so that I can compile idl files. I need to do this for one of the Firefox extension I work on. I’ve been able to put this off for a while since my interfaces haven’t changed in a while. I’ve recently changed an interface so now I need to get the idl compiling setup. When I’ve set this up in the past, I haven’t had any problems. I install the gecko sdk, install libidl, and I’m ready to roll. This time I can’t make it work so I’m turning to you, the interweb, to help me figure this out. Here is what I’ve go so far.

I install the Gecko 1.9.1 SDK from developer.mozilla.org. I then install libidl using the following commands in MacPorts:

sudo port selfupdate
sudo port sync
sudo port install libidl

Now, when I run my build script I get the error:

     [exec] dyld: Library not loaded: /opt/local/lib/libIDL-2.0.dylib
     [exec]   Referenced from: /Developer/xulrunner-sdk-1.9.1/bin/xpidl
     [exec]   Reason: no suitable image found.  Did find:
     [exec] 	/opt/local/lib/libIDL-2.0.dylib: mach-o, but wrong architecture

Figuring that libidl is compiled as 64 bit and the gecko sdk is 32 bit, I go searching the web. This leads me to a forum post on compiling Camino on Snow Leopard.

Mac OS 10.6 is 64-bit as native, while Camino is far from 64-bit ready. So cross-compiling to 32-bit is required.
First hurdle was to cross-compile and install the required libIDL library, in 32-bit. Luckily MacPorts contain a universal libIDL, so after I got the hint about “versions” I got that going using the command – “sudo port install libIDL +universal”.

Alright, so now I’m trying to install the universal libIDL file and I hit another error.

Here is where I’m stuck. I have no idea what symbols are missing. Please, leave me a comment if you have any ideas on how to make this work.
