When I compiled compress I got:
compress.c: nnnn: extra tokens (ignored) after directive
"compress.c", line 375: warning: illegal pointer combination, op =
"compress.c", line 375: warning: illegal pointer combination, op !=
where nnnn is a line number. ( there are a bunch of the first message)
I do get a compiled program. When I try to run it it gets so far and then
give a Segmentation violation -- Core dumped message. (I'm trying to
uncompress a program). The program does leave a partial uncompressed file
but it is not error-free. It contains some garbage.
Line 375 reads:
if ( (bgnd_flag = signal ( SIGINT, SIG_IGN )) != SIG_IGN )
signal ( SIGINT, onintr );
I commented out the if statement and got rid of the error message but
no change when running the program.
Also any comments on compiling and/or using epoch on a 6386 under OPEN LOOK
would be appreciated.
Thanks

The message the compiler gave is quite clear, it points out an error in the pointer assignment, obviously the return type from your signal() function doesn't jibe with whatever bgnd_flag is. I'll bet dollars to donuts your signal returns void and bgnd_flag is an int. As for your other problem, just commenting out the text after the #else or #endif will solve that problem. That error doesn't stop the compile anyway, it's just informational and clutters up the screen. -- Arthur W.
