After a bunch of what I can only fairly describe as 'fidling', I finally got this to compile under Linux. I ended up using the lex.c from version 4.5, an edited Makefile created from v4.3 (because I'm too Imake and flex challenged to fix them properly for Linux). This was compiled under kernel 2.0.18, GCC 2.7.2, and libc 5.2.18. It runs fine under XFree3.1.2G, and xview 3.2.2. The xview libraries I have claim to be xview3 compiant, but when I compiled Ftptool to use xview3, I ended up with a bunch of unresolved references, so I switched it to use xview2. Have fun. Hope it works for you. If not, you can email me (kfitzner@compusmart.ab.ca). No guarantees I'll be able to help, but I'll try. .
