By default the "FCLIBS" env is set to f2c on Linux. It is usually not found. It would be better to set it to: FCLIBS = -L/usr/lib/gcc-libs -lg2c -lnsl In my previous mail, I forgot "-lnsl" which is need with packlib.
Fixed in the development tag "config-V01-01-00". It will be included in the next public release or patch. Thanks.
