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