NetCDF: Filter error: undefined filter encountered #2727
Comments
|
First, what configure options (or CMake options) did you use? |
|
I built the library by appending the option --with-plugin-dir as follows: ./configure --prefix=/path/to/netcdf-4.9.2 --enable-s3 --with-plugin-dir=/path/to/netcdf-4.9.2/lib/plugins LDFLAGS="-L/path/to/aws-sdk-cpp/lib64 -laws-cpp-sdk-s3" CPPFLAGS=-I/path/to/aws-sdk-cpp/include CC=mpicc CPP=mpicxx This resulted that in /path/to/netcdf-4.9.2/lib/plugins I can find the related libraries: ls /path/to/netcdf-4.9.2/lib/plugins Then, I set HDF5_PLUGIN_PATH to /path/to/netcdf-4.9.2/lib/plugins as follows: export HDF5_PLUGIN_PATH=/path/to/netcdf-4.9.2/lib/plugin and now all the tests passed. |
|
Now, I am testing my application using the NetCDF library and... the same error is raised. dlopen(): /path/to/netcdf-4.9.2/lib/plugins/lib__nczhdf5filters.so.0: undefined symbol: nc_inq_var_endian The problem occurs even if LD_LIBRARY_PATH includes /path/to/netcdf-4.9.2/lib/plugins I have obtained a similar problem even over another architecture Linux n179 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux but, in this case, already the execution of dopen() results in error as follows: symbol lookup error: /path/to/netcdf-4.9.2/lib/plugins/lib__nczstdfilters.so.0: undefined symbol: nc_inq_var Could you help me to solve this issue? |
|
I'll take a look, I'm curious if the |
|
Not all filters need to use libnetcdf, so check the Makefile to see if this one has it. |
|
@WardF: my LD_LIBRARY_PATH already includes libnetcdf as I am testing an application that uses it. LD_LIBRARY_PATH=/path/to/hdf5-1.14.1-2/lib:/path/to/netcdf-4.9.2/lib:/path/to/aws-sdk-cpp/lib64 To this I have appended even the reference to /path/to/netcdf-4.9.2/lib/plugins, however without resulting in success. @DennisHeimbigner: I am going to check the Makefile of the plugins and to refer you, but I have found no solution so far. Let me say if you suggest something to do, please. |
|
I have solved simply by forcing the library to link itself. Maybe, this affects only the intended plugins, as the reflexive link does not impact the building phase (while the library does not exist yet). ./configure --prefix=/path/to/netcdf-4.9.2 --enable-s3 LDFLAGS="-L/path/to/aws-sdk-cpp/lib64 -laws-cpp-sdk-s3 -L/path/to/netcdf-4.9.2/lib -lnetcdf" CPPFLAGS=-I/path/to/aws-sdk-cpp/include CC=mpicc CPP=mpicxx I think there is a more smart approach to solve the problem but, in the meantime, we can close this issue. |
|
Try adding directory containing libnetcdf to LD_LIBRARY_PATH |
|
@DennisHeimbigner: as I replied before, LD_LIBRARY_PATH has always included the path to libnetcdf in my tests; in fact, my application exploits it and they are regularly linked: $ ldd /path/to/my/application The problem is the link between each ncz plugin and libnetcdf: even if the LD_LIBRARY_PATH includes libnetcdf (useless during the building), the plugins are built without an explicit reference to it. In fact, the ldd tool applied to a filter does not report the connection: $ ldd /path/to/netcdf-4.9.2/lib/plugins/lib__nczstdfilters.so I think that connection should rightly be established on loading the plugin, but this does not happend in my case. $ ldd /path/to/netcdf-4.9.2/lib/plugins/lib__nczstdfilters.so Then, I have no trouble to run the plugins. |
|
ok, please do ldd /path/to/netcdf-4.9.2/lib/plugins/lib__nczhdf5filters.so.0 to see where it thinks |
