I do not know why I can not load the .il file in IC5.0 linux.
I can do that well in Solaris.
I am not sure that it is the problem of IC5.0 linux or something else. But, hercules linux version looks to be having only .il file for cds446. I am not sure any people have .il file for IC50 linux,
I have the same kind of problem , when I start loadin cdsinit.user IC5 on madrake 9.1 it shows errors when reading a library file .il and .ile, and I don't have this kind of problem on 446 on sun station.
If I am not mistaken, you need to download a newer version of hercules. It comes with newer version of il and support IC5.0. Please let me know if I am wrong.
