Problem with compilation

Problem with compilation

[Przemyslaw Sliwa]

Dear All,

while trying to compile insight from the ource I get the following error


checking for a BSD compatible install... /usr/bin/install -c
checking whether ln -s works... yes
checking for ranlib... (cached) ranlib
checking for bison... bison -y
checking for ar... ar
checking for dlltool... dlltool
checking for windres... windres
checking for mig... mig
checking for main in -lm... yes
checking for wctype... yes
checking for library containing gethostbyname... none required
checking for library containing socketpair... none required
checking for library containing tgetent... no
configure: error: no termcap library found
make: *** [configure-gdb] Error 1

The run oc configure script is fine. However make fails.
I have installed a relativelly new version of the required library termcap
but
make does not recognise it at all, it seems.

I run Suse 9.1 linux on a Athln 2000+-mobile.

Do you have any ideas why the problem occurs_

Thank you fr help,

Przemyslaw

This is really a question for the gdb list, but I'll give it a go
anyway...

You say you've installed a termcap library. I presume it's somewhere
where gdb can get to it? Configure certainly doesn't seem to think that
one is available.

Here's the snippet from src/gdb/configure.in which deals with termcap:
AC_SEARCH_LIBS(tgetent, [termcap tinfo ncurses Hcurses curses])
 
if test "$ac_cv_search_tgetent" = no; then
  AC_MSG_ERROR([no termcap library found])
fi

As you can see, configure is looking for the function tgetent by linking
using "-ltermcap", "-tinfo", "-lncurses", "-lHcurses", "-lcurses". You
might try running this test manually to verify the results.

On my FC2 box, I have the packages "ncurses" and "termcap" installed. Do
you? My cvs HEAD version of gdb is linked against both of these
packages.

Hmm. Can you link against by hand? When the configure fails, there
should be a config.log or some such file in src/gdb with the exact
command(s) that configure tried to use. Are the paths all right?

$ echo foo.c
char initscr ();

int main () {
   initscr ();
   return 0;
}

$ gcc foo.c -lncurses

Then also try "-lHcurses", "-lcurses", "-lpdcurses", etc. On your system
I would expect "-lncurses" to work.

Do the same thing except substitute "tgetent" for "initscr" and try
linking against "-ltermcap".

Certainly looks like configure cannot find termcap or ncurses. Do
/usr/lib/libtermcap.* and /usr/lib/libncurses.* exist? Where did you
install these packages? If you put them into /usr/local/lib or some
other place, make sure that this directory is in LD_LIBRARY_PATH so that
the linker can find them.
