This seems like a regression in netcdf-cxx since 4.3.0 which builds fine, their git repo is also affected.
I did a git bisect. 6b6716eebc0a6291d104bb4228b8848a08d5187f is the first bad commit commit 6b6716eebc0a6291d104bb4228b8848a08d5187f Author: Julien Schueller <schueller@phimeca.com> Date: Tue Jun 13 20:18:41 2017 +0200 Add mandatory -no-undefined dll LDFLAG cxx4/Makefile.am | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) https://github.com/Unidata/netcdf-cxx4/commit/6b6716eebc0a6291d104bb4228b8848a08d5187f So another case that GNU libtool failed the developer...
Created attachment 693669 [details, diff] https://github.com/Unidata/netcdf-cxx4/pull/103 Patches to fix the undefined references.
The issue in this report seems to not occur in their git repo.
