Hi Riccardo,

I have been finishing up the final builds of all these compilers for you.

The only one left is clang/llvm-6.0, which is building now.

I’m sorry you are having troubles. I will try to get your system in tip-top shape for you.

For now, you can download any or all of these from the older systems binary server I sent you the link to:

Most of them installed without any intervention. older gcc versions on Leopard i386 can be a bit touchy.  They build best when you deactivate all ports first, and then build them. That is the way upstream builds them, against system tools. They can be touchy, and do a surprising amount of self-configuration depending on exactly which linker and assembler they detect, as well as which compiler is bootstrapping.

The only one I had to do something fancy about was gcc49. It required setting MacPorts ld64 to ld64-97, as that is close to the Leopard system compler which is ld64-85. Then it built.

I’m sorry, but I don’t think I am ever going to build these as 64bit, or universal with PPC, as it’s just too far down the list for me right now. But I think it *could* be done, if you are suitably motivated.

Best, 

Ken
