Hi all,
The new gdb support based on gdbserver is now installed
into gdb cvs head at http://sourceware.org/gdb/
To build it, you will need a little patch, so configure
accepts the arm-wince-mingw32ce target. I'm waiting
for autoconf folks to accept the mingw32ce target name,
so I can commit that patch, but in the meantime, if anyone
wants to test it, let me know, and I'll guide you. Particularly
interesting would be to hear from people with 64bit machines
that can't build the gdb in our svn.
Someone asked me about this privately.
Attached is the small patch needed to be able to build it.
Apply it to gdb-cvs/src/bfd
* build gdb with:
mkdir buildgdb
cd buildgdb
$(PATH_TO_GDB_SOURCES)/src/gdb/configure \
--target=arm-wince-mingw32ce \
--prefix=/opt/mingw32ce
make && make install
* and gdbserver with:
mkdir buildgdbserver
cd buildgdbserver
$(PATH_TO_GDB_SOURCES)/src/gdb/gdbserver/configure \
--host=arm-wince-mingw32ce \
--target=arm-wince-mingw32ce \
--prefix=/opt/mingw32ce
make && make install
* copy built gdbserver.exe to the device.
eg: copy it to \tmp\gdbserver.exe
* copy the program you want to debug to the device. You
can also strip it first with arm-wince-mingw32ce-strip before
copying to safe both space on the device and copy time.
eg: copy it to \tmp\main.exe
* run gdbserver on the device like so:
gdbserver :9999 /tmp/main.exe
9999 is the tcp port gdbserver opens for communication
with gdb. You can use whichever you like. I just find
9999 easy to type.
start arm-wince-mingw32ce-gdb like so:
arm-wince-mingw32ce-gdb main.exe
* connect to the gdbserver:
gdb> target remote :9999
gdb should connect to gdbserver, and
the main.exe program is stopped at the entry point.
* Put a break in main:
gdb> b main
issue a continue (1):
gdb> cont
Debug as usual.
(1) When you connect to a remote target, the target is
already running, so you don't issue a run, but a
continue. That is not WinCE specific, but a
consequence of how gdb/remote is designed.
Since gdb<->gdbserver uses normal tcp communication, it
doesn't depend on Activesync for anything. Of course,
to do the gdbserver.exe and main.exe uploading you could use
Activesync or Synce. You can also copy the files using
a flash card reader/writer as well.
Cheers,
Pedro Alves
