Hi there,
I am running a Win98 host system and installed Cygwin
successfully. The building of a GCC cross compiler was
also successfully for a DOS based target system using
DJGPP.
Now I want to install GDB on my host(on Cygwin) and
build it for my DJGPP target. By using the latest GDB
(gdb-20000305.tar.bz2) the configure script works
fine. But when I want to build it, I get the following
error message while 'make' is inside the gdb-folder :
bash-2.02$ make

You have multiple problems here.
It looks like something has changed which causes gdb to require the
sigtramp_saved_pc function. I wonder if this is somehow due to Mark
Kettenis's changes of 2000-03-04.
Your other problems are due to the fact that you are mixing an old
library (libtermcap.a) with a newer libcygwin.a -- _ctype_ is no longer
defined in libcygwin.a. The simple solution is to recompile libtermcap.a
using the headers and libraries in one of the cygwin snapshots.

Do you want to build a GDB executable to be run on the DOS target, to
debug the programs natively? Or do you want to build GDB that will
run on a Windows machine and debug programs on the DOS target
remotely?
A native DJGPP build of GDB only supports the former. For the latter,
you will need some kind of communications channel between the host and
the target. I don't know if the current version of GDB supports
debugging a DOS target from a Cygwin host; if not, you will need to
hack around a bit.

Please tell me how did you configure GDB. That is, what was the
command line you used to invoke the configure script.

There's something strange here: you are building a DJGPP binary, but
linking against libuser32.a, which is a Windows library. Why?

The undefined references to sigtramp_saved_pc is a known bug in GDB
when building a native DJGPP version. In fact, the DJGPP support in
current snapshots of GDB is broken, and these errors is one of the
symptoms of that breakage. I have patches to fix that, but I didn't
yet commit them to the GDB CVS tree. I will probably do that in the
next few days.
But since I'm not sure how did you configure GDB and why does
libuser32.a get linked in, I cannot guarantee that those patches will
solve your problems.

I'm guessing that the configure script found libtermcap.a on your
system and is trying to link it in. You get undefined references
because that libtermcap.a was compiled with Cygwin, not with DJGPP.
If my guess is correct, you need to move libtermcap.a out of
configure's sight. (The DJGPP version of GDB doesn't need and doesn't
use any termcap library.)

All the messages you sent me are the errors it is complaining about.

Hi there,
I am running a Win98 host system and installed Cygwin
successfully. The building of a GCC cross compiler was

fine. But when I want to build it, I get the following
