Trying to understand why Cocotron isn't creating Framework DLLs

Question

I'm attempting to use Cocotron to build the Foundation framework. GCC 4.3.1 for Windows compiled fine, and it's creating valid Windows executable files, which I confirmed by making a "Hello, world" executable.

So what I don't understand is why, with Xcode 5.0.2, when I use either xcodebuild or build the Foundation project within Xcode itself, it isn't creating dll files.

Answer 1

So, it seems that as of Xcode 5, Apple no longer supports any compilers that are not derived from clang. To fix this issue, I had to copy the pbcomspec files from /Library/Application Support/Shared/Xcode/Specifications to ~/Library/Application Support/Shared/Xcode/Specifications and edit the file that declares that the compiler is based on llvm-gcc to declare that it's based on com.apple.compilers.llvm.clang.1_0. Then it should at least try to build.

Answer 2

I try to use hpc gcc instead clang and get same results. I found that cocotron needs additional libraries zlib, libjpeg and libpng and in xcode 4.x build failed without they, but in xcode 5.x its only warnings and build marks as success. I didn't try fix it because we began use virtual machine with xcode 3.2, but maybe it is cause that libraries are not created

BTW I use this post and this plugin
