When I build GDB 5.0 with the Solaris 8 sparc version of gcc (in
/opt/sfw/bin/gcc, shipped on the Software Companion CD), I get a
program that can't be executed. 'ldd gdb' reports:
libncurses.so.4 => (file not found)
The problem is that 'configure' first looks in -lncurses for tgetent,
and /opt/sfw/bin/gcc compiles the program successfully because it
links to /opt/sfw/lib/libncurses.so, but the program doesn't run
because Sun configured gcc to use -L/opt/sfw/lib without using
-R/opt/sfw/lib when linking. Arguably this is a misfeature of Sun
gcc, but I noticed that gdb/configure.in uses a different search order
for tgetent that readline/aclocal.m4 does, and this inconsistency
should be removed anyway. Here's a patch.
2000-06-28 Paul Eggert <[EMAIL PROTECTED]>
* configure.in (TERM_LIB): When searching for libraries
containing tgetent, prefer termcap, curses, then ncurses.
This is the same order as ../readline/aclocal.m4, and it works
around a bug in the GCC 2.95.2 installation that is shipped
with Solaris 8.
