apple-gcc42 @5666.3_14, llvm-gcc42 @2336.11_1: can't build on Yosemite

[elbert.castaneda@…]

• I install Yosemite MacOS Version today
• I Install MacPorts for this MacOS Version(Yosemite)
• I execute this command : sudo xcode-select --install
• I execute this command for upgrade all packages and here it's the problem: sudo port upgrade outdated

• Error: apple-gcc42 is not supported on Yosemite or later.
• Error: org.macports.fetch for port apple-gcc42 returned: unsupported platform

[ryandesign (Ryan Carsten Schmidt)]

Correct. Sorry, this port is not supported on Yosemite right now. Are you sure you need it?

[jeremyhu (Jeremy Huddleston Sequoia)]

It will not be supported on Yosemite. Developers have had many many years to update their software for newer compilers. If you still need gcc 4.2 for some reason, please file a bug with llvm.org indicating what the issues are with clang that you need fixed.

patch to solve llvm-gcc42 build problems on 10.10

[jhowarth@…]

On fink, I have solved our llvm-gcc42 build problems with the attached patch. The first part of the patch is a back port of the upstream fix for the __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ support...

​http://permalink.gmane.org/gmane.comp.gcc.cvs/164573

and the second half adds a fixincludes entry to work around the problematic conditionals in the xpc/base.h system header by hardcoding those to

if 0

The existing packaging in fink for llvm-gcc42 builds fine under 10.10.0 with this patch applied.

[jhowarth@…]

There is one additional section to the patch that modifies the sed in llvmgcc42-2336.11/llvmCore/Makefile.rules that sets DARWIN_VERSION and DARWIN_MAJVERS. I suspect that change is only valid for 10.10 and later so you will only want to apply the patch for those releases.

The attached patch (minus the patch to llvmgcc42-2336.11/llvmCore/Makefile.rules) makes llvm-gcc42 compile for me. Thanks! I need it to compile gccxml-devel.

What was the source of the attached patch? If it was upstream gcc, it is not acceptable as it is GPL3.

Please base your changes on the version I provided in apple-gcc42, yosemite-deployment-target.patch

[jeremyhu (Jeremy Huddleston Sequoia)]

Also, your patch says "The lowest digit is always zero, as is the second lowest for '10.10.x' and above." which is an incorrect assumption to make.

Replying to jeremyhu@…:

What was the source of the attached patch? If it was upstream gcc, it is not acceptable as it is GPL3.

It looks to be largely derived from the upstream fix.

[jeremyhu (Jeremy Huddleston Sequoia)]

To larryv to fix using the changes from ​https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63810 if desired or closed as NTBF if not.
