#20372: glib2 won't build correctly on PPC machines ---------------------------+------------------------------------------------ Reporter: mta@… | Owner: ryandesign@… Type: defect | Status: assigned Priority: Normal | Milestone: Component: ports | Version: 1.8.0 Keywords: | Port: glib2 ---------------------------+------------------------------------------------ Changes (by ryandesign@…): * status: new => assigned Comment: Replying to [ticket:20372 mta@…]:
The configure script for glib2 can't figure out the endianness of the machine if there is a "-arch" parameter in CFLAGS and assumes little- endian with a warning. This causes problems in both the universal and non-universal builds of glib2 (for different reasons). Sometime recently MacPorts was changed to provide a -arch flag even in a non-universal build, this causes this build to assume a little-endian machine in all cases.
Maybe r53217.
Of course on a universal build the -arch parameter is necessary and the Portfile contains some code to deal with this. However it is incorrect and the universal build also assumes a little-endian machine in all cases.
Since the build appears to succeed (if you don't see the warning from configure), but assumes little-endian architecture, this is a somewhat subtle bug. It generates header files which may cause other programs to build incorrectly and libraries which mostly work, but fail for some calls. After fixing this bug you need to rebuild everything that depends on glib2 to be sure things will work again.
We had this problem before and fixed it; see #15816. But it must've broken again in a newer glib version. I discovered this myself again recently (using MacPorts 1.7.1 I'm pretty sure) and thought I had filed a ticket but I can't find it now. -- Ticket URL: <http://trac.macports.org/ticket/20372#comment:2> MacPorts <http://www.macports.org/> Ports system for Mac OS
