[Paraview] 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)

[Michael Jackson]

It looks like from the initial linker error that some function is NOT included in the 64 bit compile of ParaView? Are you compiling everything or using your own versions of libZ?

I try to build the plugin as a stand-alone, that is the plugin is not included in Paraview build but out of source. Note that the plugin builds and works fine on linux x86_64 (load/unload at runtime).

> 	• I can only build Paraview 3.10.1 and my plug-in with Xcode 4.0 (instead of makefiles i used before) only if i leave BUILT_SHARED_LIBS off, which is of no practical merit since the plugin is static (*.a) and cannot be loaded to Paraview. When i switch BUILT_SHARED_LIBS to on though, i get the exact same message i was getting before (failure while linking)
