Compiling error

Compiling error

[Fabian Cenedese]

Hi

I'm new to the list and also quite new to gdb. I'm trying to use gdb to work
with an embedded PPC board. After some useless fiddling around it finally
came to my mind that I need to compile my own gdb which works with
--target=powerpc-elf32.

I have MSYS/MinGW/Cygwin. Configure went ok. But make gives this:

make[1]: Entering directory `/home/Fabi/gdb-6.1.1/ppc/readline'
rm -f rltty.o
gcc -c -DHAVE_CONFIG_H   -I. -I../../gdb-6.1.1/readline -DRL_LIBRARY_VERSION='"4.3"' -g -O2 ../../gdb-6.1.1/readline/rltty.c
In file included from ../../gdb-6.1.1/readline/rltty.c:44:
../../gdb-6.1.1/readline/rltty.h:42:21: sgtty.h: No such file or directory
../../gdb-6.1.1/readline/rltty.c:166: field `sgttyb' has incomplete type
../../gdb-6.1.1/readline/rltty.c:175: confused by earlier errors, bailing out
make[1]: *** [rltty.o] Error 1
make[1]: Leaving directory `/home/Fabi/gdb-6.1.1/ppc/readline'
make: *** [all-readline] Error 2

I couldn't find this sgtty.h neither in gdb nor in MSYS, MinGW
or Cygwin. What else do I need to compile gdb on Windows?
Or should I take the DJGPP road?

Thanks

bye  Fabi

Where did you get the GDB sources?  It sounds like you are trying to
compile sources that were not ported to MinGW.

If this doesn't give you any idea what to do, I suggest to ask the
question on some MinGW-related forum (sorry, no URL), because the
solution, if it exists, is probably MinGW-specific.

The DJGPP port will build, allright (provided that you follow the
instructions in gdb/config/djgpp/README), but the resulting gdb.exe
will be unable to debug anything but DJGPP programs.  So this is not
what you want.

It's the official gdb source package. I thought with the help of cygwin I
wouldn't need any special version. But I will try the MinGW one as well.

Even with DJGPP you can run configure and --target=powerpc-elf32
seemed to work fine. There were some files missing from the official
source package but after adding them make finished fine and produced
a gdb.exe. But that didn't seem to work as expected (unknown symbol
type when reading a symbol file, network didn't seem to work either).

So if I need a cross-target gdb (running on win32, debugging ppc) is
the MinGW variant the only one that works? I thought that there are
also cygwin versions of gdb... but maybe only win32-win32.
I found the sgtty.h, it's in the glibc, so it may work ok if I install that
as well. But I first try the MinGW one.

Thanks

So I tried (and fiddled a lot!) again with MSYS and MinGW and got
a gdb.exe. But it has the same problems as the one I built with DJGPP.

This is the official http://prdownloads.sf.net/mingw/gdb-5.2.1-1-src.tar.bz2,
configured with --target=powerpc-elf32.

(gdb) target remote 127.0.0.1:10372

So it doesn't seem to be able to read my binary (which the prebuilt gdb
has no problems with) and network seems also disfunctional. How can
I go on?

(Changing --target to powerpc-eabi didn't change anything btw)

After looking through the sources I found that serial/TCP connection
won't work when built with MinGW. Are there better chances if I build
it with cygwin? Or what would it take to create a "ser-win32.c"? I'm
only interested in network connection right now, and the socket stuff
is quite similar between unix and win32. Or has anybody already
created one?

Thanks

I'd try the Cygwin build.  I don't think any other DOS/Windows based
port supports anything but the native debugging.
