Problems building GDB under cygwin and win2k

Problems building GDB under cygwin and win2k

[Andy Hare]

I have been trying to build Insight targeted on ARM under cygwin and win2k.
I have come across a number of problems with the insight side of things that
have now been fixed but GDB fails to build with the following error;

gcc -g -O2        -Wl,--subsystem,console -o gdb.exe \
main.o libgdb.a cli-decode.o cli-script.o cli-cmds.o cli-setshow.o

This is the last stage of creating gdb.exe. I have checked though
gdb/utils.c to find the errors and find that the missing refernces are all
in a section surrounded by a #ifndef _win32. With the this I realise that
maybe the gdb directory should be built with the -mwin32 construct in the
command line. Having done this I get a successful build. My question is this
the correct solution or is there something else going wrong. I know there
have been problems of late with insight and cygwin and have helped to fix
these, is this a case of the same problems.

The gdb source is from the cvs last night and I am running the latest
cygwin.

It looks like you haven't built libtermcap.a for some reason and gdb is
finding a libtermcap.a from some other library (ncurses?) which
represents a shared library.

gdb on Windows is not supposed to be using any shared libraries besides
cygwin1.dll.

Have put a copy of libtermcap.a in the appropriate directory in the source
tree and re-linked the code. The version came from the usr/lib directory of
the cygwin installation. This still does not work so maybe this is still a
shared library. Any ideas where I can get the source code for the libtermcap
sub-directory to try that.
