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
