#49273: clang-mp-3.7 and MACOSX_DEPLOYMENT_TARGET=10.3 do not mix ----------------------+------------------------ Reporter: jhi@… | Owner: jeremyhu@… Type: defect | Status: closed Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: invalid | Keywords: Port: clang | ----------------------+------------------------ Comment (by jhi@…):
This has nothing to do with the deployment target. This has to do with the text based stubs support.
Well, the deployment target is how the error became visible, as you can see from my example. Are you saying the clang-mp-3.7 was just lucky to work (to compile and link) when being compiled without the deployment target?
I think this is the problem where you need to reinstall the ld64 port with the +ld64_xcode variant ("sudo port install ld64 +ld64_xcode") because earlier versions of ld64 don't understand the changes that were made in Xcode 7.
Use the +ld64_xcode variant of ld64 to get this to link for now. +ld64_latest will support text based stubs once opensource.apple.com drops an updated ld64 from Xcode 7 which we can pull in.
Umm, thanks, never heard of this ld64 thing. ld64_xcode? ld64_latest? Is there some documentation for the use of these options? (I'd like to amend the Perl build instructions, if there is). For example, from the above it sounds like one should normally use +ld64_xcode ... exactly when? Always? But you are also saying that this is a transient failure, that +ld64_latest will eventually understand XCode 7?
But why are you setting MACOSX_DEPLOYMENT_TARGET to 10.3 when you're compiling for Intel? There were never any Intel Macs running Mac OS X 10.3.
Why are you using such an old deployment target. We didn't even have intel support until 10.4.x
This is actually an open question in the Perl project, if you have feedback/opinions on that, it would be great. We know that the 10.3 target is getting a little bit old... but we are a little bit cautious over dropping the support for older OS X-es. That is, if a Perl would be compiled now without a deployment target (defaulting to the compiling OS X), how bad would it be if run in older OS X-es? -- Ticket URL: <https://trac.macports.org/ticket/49273#comment:3> MacPorts <https://www.macports.org/> Ports system for OS X
