[vtk-developers] libvtkproj4 problems with gcc on Mac

[Dan Lipsa]

Hi Bill,
I don't have access to a machine with that configuration.
Can you try
dsymutil -s ./lib/libvtkproj4-7.1.dylib | grep acquire_lock

It seems that this symbol should be defined as an empty function
if PROJ_USE_PTHREADS:BOOL is off.
Also it seems that mangling should happen correctly.
