As I noted, you may be able to add an option to gcc to show the specific
files it opens. But in the instance where you used -v, I only saw the
specs file listed.
$ gcc -v ../objects/tic.o ../objects/dump_entry.o -I../progs -I.
-DHAVE_CONFIG_H -I. -I../include -D_OSF_SOURCE -DNDEBUG
-I/usr/home3/mmokrejs/include/ncurses -O2 -o tic -L../lib -lncurses
Reading specs from /usr/local/lib/gcc-lib/alphaev68-dec-osf5.1/3.3.4/specs

Making simpler the above compile/linker command while retaining
-lncurses makes the linking step fail again:
$ gcc ../objects/tic.o ../objects/dump_entry.o -I../progs -I.
-DHAVE_CONFIG_H -I. -I../include -D_OSF_SOURCE -DNDEBUG
-I/usr/home3/mmokrejs/include/ncurses -O2 -o tic -lncurses
_nc_first_name
...
On this instance I don't see a -L option.
You were right, I forgot that. But still, it does not work:
$ gcc ../objects/tic.o ../objects/dump_entry.o -I../progs -I. -DHAVE_CONFIG_H
-I. -I../include -D_OSF_SOURCE -DNDEBUG -I/usr/home3/mmokrejs/include/ncurses
-O2 -o tic -L../lib -lncurses
_nc_first_name
_nc_set_type
_nc_curr_line
...
$
So gcc will pick up libncurses from its preferred location, e.g.,
/usr/local/lib
Let's link statically the new libncurses.a ...
$ gcc ../objects/tic.o ../objects/dump_entry.o ../lib/libncurses.a
-I../progs -I. -DHAVE_CONFIG_H -I. -I../include -D_OSF_SOURCE
-DNDEBUG -I/usr/home3/mmokrejs/include/ncurses -O2 -o tic
I'd like to solve it this way - but recall some linkers simply put the
entire contents of the ".a" file in the output.
But one can test for such broken linkers, right? ;-)
