Glad to hear you’re trying to make some progress now. It’ll be good to have
that converter finished and integrated with all the progress you worked so hard
on.

That error is saying it can’t find the gzopen and gzdirect symbols. Those
symbols are in libz/zlib. This is a consequence of using libxml2, which
apparently uses libz/zlib.
To fix, you need to make the build files to say that libz is needed. If you
added libxml2 to src/other, you’ll want to add ${ZLIB_LIBRARY} to a
target_link_libraries() line libxml’s build. If you did not add it, you can
specify it on the BRLCAD_ADDEXEC line in the src/conv/3dm/CMakeLists.txt build
file for 3dm-g. It’ll have a line that looks something like (but not exactly
like) this:
BRLCAD_ADDEXEC(3dm-g 3dm-g.cpp "libgcv;libwdb;libicv;${OPENNURBS_LIBRARY}”)
That would get changed to:
BRLCAD_ADDEXEC(3dm-g 3dm-g.cpp
"libgcv;libwdb;libicv;${OPENNURBS_LIBRARY};${ZLIB_LIBRARY}”)
Cheers!
