#nnfyboot

Recently I had to install 10.2.0.4 on a RHEL 6 server to test an upgrade. The base install of 10GR2 went fine, but when I tried to install the 10.2.0.4 patchset I got some errors in the linking phase:

libclntsh.so: undefined reference to 'nnfyboot' libagtsh.so: undefined reference to 'nnfyboot'

Google results seemed to be focused around Ubuntu, and the workarounds did not apply on Redhat. It turns out the fix was really quite simple:

cd $ORACLE_HOME/network/lib make -f ins_net_client.mk nnfgt.o $ORACLE_HOME/bin/relink all

It seems that the 10.2.0.4 installer doesn't recreate nnfgt.o by itself.
