CentOS 8 - /usr/bin/ld: cannot find -lnsl

I am working on a new CentOS 8 server to replace an aging CentOS 6 server. Most everything is working and I am having the primary users test out everything they use the server for. Many errors have come and gone but this one not so much. The user is running a gcc command: gcc process-hdf.c -o process-hdf.exe -I/usr/include/hdf -L/usr/lib64 -lmfhdf -ldf -ljpeg -lz -lnsl -lm which ends up failing with /usr/bin/ld: cannot find -lnsl I have done the following so far: - Ran ld -l nsl, same error as with gcc. - Verified that libnsl is installed within /usr/lib64. - Verified both packages, libnsl and libnsl2 are installed. - Checked the ldconfig cache and both versions of libnsl are listed. - Removed the libnsl package, other packages depend on libnsl2. No change when removed. Any info would be appreciated.
