Can you double check that the macro cur_term is defined in curses.h on your system?

[larsbrinkhoff]

This sometimes happen when you rebuild in a previously built tree. The problem is usually resolved by ensuring all submodules are up-to-date and clean. Do something like this:

1. git submodule sync --recursive
2. git submodule update --recursive --init
3. git submodule foreach --recursive make clean

I suspect that point 3 is solves the issue indirectly, since it will nuke all built artifacts. Just running make clean in supdup should do the same; but it is weird that this happens .. cur_term is a macro, so it should already be expanded at some point or something...

[drforbin]

fine. but it did the same thing on build from clean clone

[drforbin]

cur_term is defined in term.h in /usr/include

[ams]

Can you try doing something like:

cd /home/mercou/Documents/sims/its/tools/supdup
make clean
make all

This should result in the same error, I hope. If it does, canyon then try doing, maybe:

cc -g -o supdup supdup.o charmap.o tcp.o chaos.o -lncurses -ltinfo

[drforbin]

I did it. it compiled properly. tfinfo lib had to be added?

[ams]

Seems like it, there are cases that escape me where -lcurses AND -ltinfo need to be passed. Why I don't recall. Maybe this can be fixed somehow, @larsbrinkhoff ?

[drforbin]

Well, do you want me to add the lib and post a pull request? or you do it?

[larsbrinkhoff]

This is a matter for https://github.com/PDP-10/supdup, and when that's resolved we'll pick up the new version in #2321. I'm closing this issue; let's move further discussion to the supudp repository.

[drforbin]

Do you guys want me to update the make file and do A pull request?

[ams]

Not sure what you mean? Are you confusing this with PDP-10/supdup#35 ?

[drforbin]

Well I had problem building. It was found that the tinfo lib was required. I added this to the make file and I wanted to know if you all wanted me to fix the rep and you all do a pull?

[larsbrinkhoff]

Thank's for offering @drforbin, but adding tinfo is already being adressed in the pull request @ams referred to. So it should be fixed soon.

[drforbin]

oh ok. I had done a pull a few days ago and the fix was not in.
