[Paraview-developers] cannot link Plugin based on Paraview 3.10.1 using Qt 4.7.4 on Mac OS OX 10.6.8 | gcc 4.2.1 | Xcode 4.0 | CMake 2.8-2 (x86_64 is on)

[nikos yiotis]

I switched to a .pro file and qmake for building the plugin.

qmake -project outputs a src_qmake.pbproj file that i rename to
src_qmake.xcodeproj.

I cannot launch src_qmake.xcodeproj, it complains about incompatible project
version.


any mac PV users/developers out there? thanks
