#47929: llvm-gcc42 @2336.11_2 fails building on 10.6.8 -------------------------+-------------------------------- Reporter: braumann@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.3 Resolution: | Keywords: Port: llvm-gcc42 | -------------------------+-------------------------------- Changes (by ryandesign@…): * keywords: Symbol not found: _strncmp => * cc: ryandesign@… (added) Comment: Replying to [ticket:47929 braumann@…]:

While updating {{{llvm-gcc42}}} from {{{2336.11_1}}} to {{{2336.11_2}}} on 10.6.8 I was surprised to run into trouble like {{{dyld: lazy symbol binding failed: Symbol not found: _strncmp}}}.

Hmm. Yesterday's update of llvm-gcc42 was done for the benefit of Yosemite, on which llvm-gcc42 couldn't be built until now. It's certainly possible this has introduced problems for earlier platforms, though this was not intended.

BTW, I am wondering that {{{llvm-gcc42}}} itself is being automatically selected for building.

Well, the llvm-gcc42 port will not build using a compiler installed by an already-installed llvm-gcc42 port. What you're seeing in the log is that the llvm-gcc42 port is being compiled using the version of the llvm-gcc42 compiler that came with Xcode. Theoretically, that should work. However, on my Snow Leopard system, Xcode gcc42 is used, not llvm-gcc42, and I don't see anything in the llvm-gcc42 portfile that would explain why Xcode llvm-gcc42 was selected instead on your system. Do you really need MacPorts llvm-gcc42? Is the version provided by Xcode not sufficient for your needs? It is true that the MacPorts version is ever so slightly newer than the version provided by Xcode, but there are only a few small differences.

Below is the most relevant excerpt. I am hesitating to directly report to [http://developer.apple.com/bugreporter]

You're probably right not to report this to Apple; they've moved on from llvm-gcc. We keep it around mainly for the benefit of very old software that has not yet been fixed to compile properly with clang on newer systems. -- Ticket URL: <https://trac.macports.org/ticket/47929#comment:1> MacPorts <https://www.macports.org/> Ports system for OS X

Originally, I had Xcode 3.2.6. Xcode 4.2 is the highest Xcode version running on 10.6.8. I was not aware that installing Xcode 4.2 influences preferences for compiler selection inside MP. -- Ticket URL: <https://trac.macports.org/ticket/47929#comment:3> MacPorts <https://www.macports.org/> Ports system for OS X
