Unable to link on Snow Leopard (Xcode 3.2.6)
« on: August 23, 2011, 03:38:17 PM »
When I attempt to link justthread-mp-4.5.a I get the following error "file was built for unsupported file format which is not the architecture being linked (x86_64)".

I've removed the "x86_64" from the list of valid architectures and I'm only trying to build against the 32-bit Intel architecture.

Xcode's build command starts with "g++-4.5 -arch i386 -isysroot" and then is followed by paths to headers, sources, etc. So things appear to be right.

What am I missing?

It does seem like the linker is trying to link an x86_64 binary. Can you post a sample project that demonstrates the problem?

I tried a couple times to post the attachment and was met with an "Internal Server Error". Doh!

I've uploaded it to my website http://www.migrap.com/tmp/Threads.zip

Sorry about the problem you encountered with uploading an attachment.

With regards to your problem, it should just be a matter of doing a Clean from the Build menu in XCode. For some reason, XCode had built an x86_64 object file from main.cpp, but wasn't rebuilding it for i386.

If you are still having problems, let me know.

I think I figured it out. I'm not sure exactly what I did, but it works. I'm going to try to replicate it on my laptop now and figure out what minimally has to be done. I know I had to do some pretty extravagant things and I'd like to see if I can simplify.

Thanks for the help!!!
