Paraview Plugin based on Qt fails to link on Mac OS OX (10.6.8 Snow | gcc 4.2.1 | Qt 4.7 | CMake 2.8-2 | x86_64 is on)
-
i built the plugin with a simple makefile. What confuses me is the successful build of the plugin as a static lib and the failure of a shared lib.. My configuration for these two cases is the same..
-
I would recommend using a .pro file and qmake for building your pluging.
Anyways, make sure you add the following switches to the command line arguments of your C/C++ compiler and the linker:
@
-arch x86_64 -arch i386
@This will build 32bit and 64bit code for intel processors. You might want to add other archs as well (ppc, ppc64) if needed.

thanks Volker. is there any automatic script for converting my CMakeLists.txt of the plugin to a .pro file
(something more advanced than qmake -project)? or the converse of this report
http://developer.qt.nokia.com/quarterly/view/using_cmake_to_build_qt_projects ?
i guess Cmake works better for building Paraview (same family), but for Qt plug-ins i should use Qmake.. -
as for the arch flags, they are there in both Xcode and command line
-
qmake -project outputs a src_qmake.pbproj file that i rename to src_qmake.xcodeproj. Is this the expected behavior? I cannot launch src_qmake.xcodeproj, it complains about incompatible project version.
thanks

"qmake -project" usually outputs a xyz.pro file (with xyz being the directory name you're in).
If you want an XCode project generated out of the .pro file, you need to issue:
@
qmake -spec macx-xcode

thanks volker, i was going with qmake -spec macx-g++ and was expecting an xcode project
-
qmake -spec macx-g++ generates a regular Makefile. You can build it with make.

I was too fast in replying..
qmake -project and then qmake -spec macx-xcode outputs src_qmake.pbproj that i rename to src_qmake.xcodeproj. as i 've written earlier on, this is not loaded in Xcode.. -
something is seriously going wrong there.
@
qmake -spec macx-xcode
@should create a directory named src_qmake.xcodeproj, which in turn contains a file named project.pbxproj.

OK, sth is wrong indeed. in a hello directory consisting of hello.cpp and hello.pro i go with
@qmake -spec macx-g++@ and the little gui (hello.app) builds fine, whereas with
@qmake -spec macx-xcode@ i get a hello.pbproj and the related plist without any Xcode directory.
i 'll build qt from scratch, thanks
