#15750: build libxml2 with two-level namespace ---------------------------------+------------------------------------------ Reporter: ricci@macports.org | Owner: macports-tickets@lists.macosforge.org Type: defect | Status: new Priority: Normal | Milestone: Port Bugs Component: ports | Version: 1.6.0 Resolution: | Keywords: ---------------------------------+------------------------------------------ Comment (by ricci@macports.org): Well, it is related to auto*/configure/libtool, so it is kinda magic (the dark kind...). Something in the libxml2 package (sorry, I'm not remembering what it was for libxml2, been diving into too many different packages recently) doesn't understand which rev. of Mac OS X (darwin) its running on (and doesn't seem to pick up MACOSX_DEPLOYMENT_TARGET to know), so sets -flat_namespace. This results in binaries linked against MP libxml2 that will pull in both MP libxml2 (via the linking they have) and the system- installed libxml2 (via other libs they use, including system frameworks). Then while running the binary will call functions in the "wrong" libxml2, resulting in crashes. Redoing the autoconf stuff teaches/fixes "it" (configure or libtool I think) to not include -flat_namespace, and all is good. You can check if a dylib is built with two-level namespace with: otool -hv PATH/TO/LIBRARY and look in the 'flags' section, there should be a 'TWOLEVEL' word in there if it was built with two-level namespace. -eric -- Ticket URL: <http://trac.macports.org/ticket/15750#comment:3> MacPorts <http://www.macports.org/> Ports system for Mac OS

Are you saying you'd like the autoreconf.cmd line to be above the use_autoconf line? I can commit the fix if you'd like, let me know. -- Ticket URL: <http://trac.macports.org/ticket/15750#comment:5> MacPorts <http://www.macports.org/> Ports system for Mac OS

Installing libtool (from MP) resolved the problem. Unless there's an objection, I'll add a dependency on libtool to libxml2. -- Ticket URL: <http://trac.macports.org/ticket/15750#comment:11> MacPorts <http://www.macports.org/> Ports system for Mac OS

With another ticket open on it, no rebuild issues (revision bump or anything like that), and it fixes a build problem for people, it seemed like the right idea. We can always back it out if there's a problem with it. -- Ticket URL: <http://trac.macports.org/ticket/15750#comment:15> MacPorts <http://www.macports.org/> Ports system for Mac OS

I know that it does need a [http://lists.macosforge.org/pipermail/macports- users/2008-July/011081.html build-time dependency on port:autoconf] since you're now using the autoreconf command that the autoconf port provides. -- Ticket URL: <http://trac.macports.org/ticket/15750#comment:17> MacPorts <http://www.macports.org/> Ports system for Mac OS

The port libxml2 failed to build due to the lack of libtool related macros for autoconf. Installing port:libtool fixed it. I think the libtool dependency is required since it provides share/aclocal/libtool.m4. -- Ticket URL: <http://trac.macports.org/ticket/15750#comment:19> MacPorts <http://www.macports.org/> Ports system for Mac OS
