Description of problem:
The nco package is built with versions of other libraries that are no longer in EPEL. For instance running the ncks program produces an error stating that it cannot find libhdf5_hl.so.7. This is because the hdf5 package includes libhdf5_hl.so.8 instead. Similar with libcurl.so.3 instead of libcurl.so.4.
I created links to correct this but still there is a problem:
ncks: symbol lookup error: /lib64/libnco-4.4.4.so: undefined symbol: nc_inq_format_extended
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. yum install nco
2. extract a var from a netcdf file:
ncks -O -v time my_file.nc test.nc
ncks: error while loading shared libraries: libhdf5_hl.so.7: cannot open shared object file: No such file or directory
file test.nc would be created with the time variable in it
I can't reproduce this. My nco is linked with the proper hdf5 library:
# ldd /usr/lib64/libnco-4.4.4.so | grep hdf
libhdf5_hl.so.8 => /lib64/libhdf5_hl.so.8 (0x00007f2ee3a0d000)
libhdf5.so.8 => /lib64/libhdf5.so.8 (0x00007f2ee3412000)
What is the output of:
yum list nco
rpm -Va nco
rpm -qi nco
Sorry for the noise. It looks like LD_LIBRARY_PATH was getting in the way that contained a netcdf libraries with the version 7 HDF libraries. Again, apologies. I should have found this.
Thanks for your help.
