#37256: gobject-introspection: building non-universal i386 fails when python27 is installed universal i386 x86_64 --------------------------+----------------------------------- Reporter: ryandesign@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Low | Milestone: Component: ports | Version: 2.1.2 Keywords: | Port: gobject-introspection --------------------------+----------------------------------- This one's interesting. Installing gobject-introspection without the universal variant fails when build_arch is i386 (i.e. on Leopard, presumably on Tiger too) on a 64-bit Mac if python27 is already installed universal for i386 and x86_64. (I changed my universal_archs to this in macports.conf.) The error message is: {{{ Traceback (most recent call last): File "./g-ir-scanner", line 44, in <module> from giscanner.scannermain import scanner_main File "./giscanner/scannermain.py", line 34, in <module> from giscanner.dumper import compile_introspection_binary File "./giscanner/dumper.py", line 28, in <module> from .gdumpparser import IntrospectionBinary File "./giscanner/gdumpparser.py", line 31, in <module> from .transformer import TransformerException File "./giscanner/transformer.py", line 27, in <module> from .girparser import GIRParser File "./giscanner/girparser.py", line 26, in <module> from .girwriter import COMPATIBLE_GIR_VERSION File "./giscanner/girwriter.py", line 25, in <module> from .xmlwriter import XMLWriter File "./giscanner/xmlwriter.py", line 74, in <module> from _giscanner import collect_attributes File "./giscanner/libtoolimporter.py", line 66, in load_module mod = imp.load_module(name, open(realpath), realpath, (extension, 'rb', 3)) ImportError: dlopen(./.libs/_giscanner.so, 2): no suitable image found. Did find: ./.libs/_giscanner.so: mach-o, but wrong architecture make[2]: *** [GLib-2.0.gir] Error 1 }}} The problem is that 64-bit is considered better than 32-bit so python27 runs 64-bit, then is surprised when it cannot find a 64-bit _giscanner.so. The workaround I used was to install gobject-introspection universal as well. Perhaps it's an esoteric case, since most users aren't on Leopard anymore and most of those that are haven't changed their universal_archs, but I wanted to at least document the problem and the workaround. -- Ticket URL: <https://trac.macports.org/ticket/37256> MacPorts <http://www.macports.org/> Ports system for Mac OS
