Dave, I believe there is some mangling missing after your change. I just pulled VTK from git and my app, which links to both NetCDF and VTK, no longer links. Error is: ld: duplicate symbol _nc_inq_type in /path1/libnetcdf.a(nc.o) and /path2/ libvtkNetCDF.a(nc.c.o) If I do the following: nm libvtkNetCDF.a | grep " [TRD] " It lists several symbols that aren't prefixed by vtk_netcdf, namely: 0000000000003083 T _nc_inq_type 0000000000000043 T _nextUTF8 00000000000008ae T _nulldup 00000000000018ae T _utf8proc_NFC 0000000000001860 T _utf8proc_NFD 000000000000194a T _utf8proc_NFKC 00000000000018fc T _utf8proc_NFKD 0000000000001998 T _utf8proc_check 0000000000000343 T _utf8proc_codepoint_valid 0000000000000fd1 T _utf8proc_decompose 00000000000005d9 T _utf8proc_decompose_char 00000000000003c6 T _utf8proc_encode_char 0000000000000000 T _utf8proc_errmsg 000000000000054b T _utf8proc_get_property 00000000000000cf T _utf8proc_iterate 000000000000172b T _utf8proc_map 000000000000126a T _utf8proc_reencode nc_inq_type certainly should be in vtk_netcdf_mangle.h, not sure why/how you missed it. My experience with updating VTK's freetype is that one must regenerate the symbol list on all the major platforms and merge the results. Some symbols seem to only be exported on some OSes, see my comments in vtk_freetype_mangle.h. Not sure about the other symbols. "utf8proc" looks like 3rd party code used by NetCDF itself. I wonder if these symbols should not be exported at all, I'm guessing they are not part of NetCDF's public API.
