Build process is pretty broken. After applying the patch below you may need to run first build with dpkg-buildpackage -rfakeroot --no-pre-clean
as package tries to make clean
without running autogen first.
If build fails because linker errors like
make[2]: Entering directory '/tmp/cnijfilter-source-3.80-1/cngpijmon/cnijnpr/cnijnpr'
gcc -O2 -L../../../com/libs_bin64 -L../../../lgmon/src -o cnijnpr cnijnpr.o -lcnnet -lbscc2sts -ldl
/usr/bin/ld: cannot find -lbscc2sts
collect2: error: ld returned 1 exit status
