#35310: netpbm broken under xcode 4.4 -- clang problem --------------------------------+------------------------------------------- Reporter: perry@… | Owner: macports-tickets@… Type: defect | Status: new Priority: High | Milestone: Component: ports | Version: 2.1.1 Keywords: | Port: netpbm --------------------------------+------------------------------------------- Description changed by jeremyhu@…: Old description:

It appears that clang lacks some of the intrinsics supplied by gcc, and that building netpbm under xcode 4.4 results in the following error message. This is rather important, as netpbm is a dependency of many packages.

#35310: netpbm needs to use standard intel interfaces rather than gcc __builtins ----------------------+------------------- Reporter: perry@… | Owner: cal@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.1.1 Resolution: | Keywords: Port: netpbm | ----------------------+------------------- Comment (by ryandesign@…): Replying to [comment:6 jeremyhu@…]:

r95870 should work around the issue for now, but it should still be fixed.

In netpbm 10.60.00 they changed their check to no longer try to use these GCC-specific functions with clang so I removed the patch in r112197. Replying to [comment:7 cal@…]:

Jeremy, do you want to take this upstream? Other than the line you wrote I have no idea what the problem is about, but you seem to have more information. The website suggests mailing to the local part bryanh below giraffe-data.com.

I emailed the developer about this. -- Ticket URL: <https://trac.macports.org/ticket/35310#comment:12> MacPorts <http://www.macports.org/> Ports system for OS X
