That is a result of Mr. McQueer having used only the Berkeley regex code, even on his SYS5 system. I had to make a major hackup to make the SYS5 regex work on the prior release of vn, and when I get the time I will do it Yet Again for this one. I had tried to send my changes to bobm but every mailer address falls into a black hole or bounces, so this was not unexpected. > Eric Kozowski AT&T GBS Portland, OR -- "To prevent having to tell fools to RTFM don't let on you WTFM to begin with."

Look up regcmp in the permuted index. You'll find man pages listed in section 3, which is in the Programmer Reference Manual. There you will see that 'this routine is kept in /lib/libPW.a'. If you are familiar with ld, or read the man pages (Section 1, User Reference Manual), you will know that such a library is automatically included by putting the shorter -lPW on the cc command line. So, let's edit the Makefile. Comment out the LIBS definition, and replace it as follows: #LIBS = -ltermcap LIBS = -lcurses -lPW We'll do one thing more; curses is a later replacement for termcap, and usually a bit better, so we substitute that library as well. If you turn out to have screen problems for some reason, you can alternatively use: LIBS = -lcurses -lPW Once you've edited the Makefile, re-make vn. This should work. Hope you have good fortune with it.

My problem with vn is that after some runs it he/she cannot start backgroung
runs. The problem is with tostop. Normally the stty setting for tostop
is -tostop. Vn sets it to tostop and never sets it back to -tostop.
Since I am not a big C programer here is what I did to get around the
problem.
We are running ULTRIX on a VAX 8650.
Here is the shell called vn:
/usr/local/bin/VN $@
stty -tostop
Is there a fix to the vn program which will correct this problem?
Thanks in advance.

Hope you have good fortune with it. This will get you past linking the program but the first attempt to match a regular expression might just cause a segmentation violation.

It took me a while to dig out the fact that regcmp and regex are functions you can only access through the libPW.a file, which is usually in /lib. About halfway down the Makefile there are three lines used when compiling under sysV. The line that defines the LIBS variable should be: LIBS = -ltermcap -lPW If you're using V/AT you'll need to modify the PW filename to include the small or large model size as appropriate. I don't have V/AT so I'm not sure exactly how that's done. It is discussed briefly under regcmp(3x).
