I am trying to install TexGen from source on OS X 10.10 .
I get the following (below) error when trying to 'make' TexGen. I note that I am using VTK5.10, which I have built from home-brew and from source, but I get the same error. Looking at the install of VTK I can find a folder 'vtkzlib'; and ccmake for TexGen in happily finding the VTK directory folder. Cant find any hints online re vtkzlib issues.
I haven't built TexGen on OS X myself (and am not sure whether anyone else has managed to do so) so am not sure how much help I will be.
Have you definitely built the vtkzlib project? Presumably the folder you have found has the make files etc in it but can you see the vtkzlib.lib (or OS X equivalent ) in your build folder? (On my Windows system this is in c:/vtk5.10.1/64-bitBuild/bin/Release where VTK_DIR is specified as c:/vtk5.10.1/64-bitBuild). This is all that springs to mind at the moment. I'll take a look when I next boot up in Linux to see what things look like there and let you know if I can see anything then.
