I got some encouraging comments offline. I know
there must be some way the static link works,
because it works somehow for others. And it
used to work for me!
In response to one of the emails I got, I'm pretty
sure I'm NOT using the SDL version. I was using the
".a" file under win32 directory. I don't even
know what SDL is...
Using the instructions in win32\README, I tried
compiling to the ".a" static library myself.
1) The library compiled (after changing copy to cp),
but I got some error messages. Any suggestions?

2) Anyway, the library did compile. So I used the resulting
pdcurses.a file (after renaming to libpdcurses.a). But when
I try to compile my program, there are some more "multiple
definition" errors at the link step. Any suggestions here?

Do I need to compile pdcurses.a? Or should I be able to use
pdcurses.a that came with the distribution?
Thanks

Hi again,

I assume -lXCurses means -lpdcurses. Anyway, I thought libraries
always came after objects when compiling. But, for the sake of
completeness, here's what I tried:
A) gcc -o vn.exe $(OBJS) -Lc:/pdc/win32 -Lc:/vn -lpdcurses -lvn -lm
B) gcc -o vn.exe $(OBJS) -Lc:/pdc/win32 -Lc:/vn -lvn -lpdcurses -lm
C) gcc -o vn.exe -Lc:/pdc/win32 -Lc:/vn -lvn -lpdcurses -lm $(OBJS)
D) gcc -o vn.exe -Lc:/pdc/win32 -lpdcurses $(OBJS) -Lc:/vn -lvn -lm
A) results in undefined reference to curses functions (eg, waddstr)
B) compiles, but then requires the pdcurses.dll to run
C) results in undefined references to functions in libvn.a
D) results in undefined reference to curses functions (eg, waddstr)
In my continuing floundering, I also tried using "-static" gcc
flag, but that did not help. Could someone please advise what
I'm doing wrong or need to do different?
Thanks,
Daniel Goldman

Hi,
I swear I used to statically link pdcurses into an
application. I few months back (for some reason) I
reinstalled pdcurses. Now I can't static link.
I use pdcurses 3.4 / mingw gcc. I'm very familiar with
makefiles and gcc. I'm sure it's something I'm doing
wrong. I've tried different ways. But I'm kind of
floundering. It compiles OK. But when it runs, it
gives an error message unless the DLL is in the path.
So I'm using pdcurses.dll for now. But I don't want
to be limited. I'd like to have static linking too.
I looked through the docs and mailing list, and came
up empty. Am I supposed to be able to statically link
libpdcurses.a file? Any example? Do I need to recompile
.a library archive? Could someone please advise?
Thanks,
Daniel Goldman
