swarm installs headers which conflict with system headers

[jmstephensjr@…]

I have tried to install this port several times in the last few days. All attempts failed. This port now required for gcc 4 series.

System as follows:

• Mac 10.6.8
• MacPorts 2.0.4

Thanks in advance.

You should attach the file print_objc.pp.c from your Desktop.

[jeremyhu@…]

Also, if you could try compiling it with clang, it will give better information about the problem, so please give that a try as well.

[jmstephensjr@…]

As requested, I have attached the file (print_objc.pp.c) generated by gcc-4.2

[jmstephensjr@…]

using gcc-4.2

[jmstephensjr@…]

As requested, I have attached the file (print_objc.pp.c) generated by clang (ver 1.5)

[jmstephensjr@…]

using clang v1.5

[jmstephensjr@…]

Another detail... I am using Xcode 3.2.3

[jeremyhu@…]

Can you attach the error message as generated by clang (not the preprocessed source)?

[jeremyhu@…]

Ok, so /opt/local/include/objc/objc-api.h and /usr/include/objc/message.h are in conflict.

What port provides /opt/local/include/objc/objc-api.h? Can you please attach both /opt/local/include/objc/objc-api.h and /usr/include/objc/message.h

[jmstephensjr@…]

RE ownership of objc-api.h:

---

~ $ port -v provides /opt/local/include/objc/objc-api.h 
/opt/local/include/objc/objc-api.h is provided by: swarm

Files objc-api.h and message.h now attached.

[jmstephensjr@…]

removed swarm and tried to compile/install (success)

[jmstephensjr@…]

FYI. I removed swarm, did a clean --all on swarm and cctools, and reran compile and install on cctools. SUCCESS. I have attached the output from the compile and install of cctools. Notice there are many "implausible timestamps" and many warnings, but it did compile and install.

[jeremyhu@…]

Thanks, I'm installing swarm now to see if I can figure out more of what is going on, but it looks like a swarm bug.

[jeremyhu@…]

Yeah, this is definitely a swarm bug. It's installing headers from gcc's objc runtime. This is clearly wrong, and I highly doubt that anything built against it will even work with the OSX ObjC runtime.

[jeremyhu@…]

swarm doesn't even build for me on SL (XCode 4.2), Lion (XCode 4.3), or ML.

[jeremyhu@…]

r92459

[jeremyhu@…]

Note that it still doesn't build for me except on Leopard, but at least now you won't shoot yourself in the foot with bad ObjC runtime headers from a rogue port.

[jmstephensjr@…]

Many thanks.
