Subject: Objective C cross compiler recipe?
Date: Fri, 20 Nov 2009 11:42:45 -0800 (PST)	[thread overview]
Message-ID: <721719.79016.qm@web53912.mail.re2.yahoo.com> (raw)

I am working on an OMAP project and I have been asked to include some Objective-C code into the project.  

I am looking at the build process and it looks like gcc-4.3.3 is built with objective C support, but I don't see the headers or runtime library installed anywhere for cross compilation.  

GCC, as put in ./tmp/cross/armv7a/bin, seems to know objective-c but does not know where to find its header files (and I assume its runtime will be an issue right after that)

arm-angstrom-linux-gnueabi-gcc main.m
>main.m:1:24: error: objc/Object.h: No such file or directory
>In file included from main.m:2:
>List.h:4: error: cannot find interface declaration for ‘Object’, superclass of ‘List’
>main.m: In function ‘main’:
>main.m:8: warning: ‘List’ may not respond to ‘+new’
>main.m:8: warning: (Messages without a matching method signature
>main.m:8: warning: will be assumed to return ‘id’ and accept
>main.m:8: warning: ‘...’ as arguments.)

I was hoping that someone who is familiar with the GCC recipes might be able to provide some guidance on this.

Anyone have any experience with this?  

Thanks,

Charlie
