Cross Compiling the GDB 6.0 branch

Cross Compiling the GDB 6.0 branch

[Chris.Pedley]

Hi,

I checked out the gdb_6_0-branch earlier today and am having some trouble
cross compiling this for ARM Linux (its all building fine to use locally on
my Intel box).  Just to clarify - I'm trying to build a gdb to be run on an
ARM Linux machine, debugging ARM applications but built on an Intel box
(host=arm-linux, target=arm-linux, build=i686-linux).

When configuring readline the following error is reported:
checking for mbstate_t... configure: error: cannot run test program while
cross compiling

Unlike errors about cross compiling when configuring readline whilst
building gdb 5.3, this error does stop the build.  I've tried hunting
around for a --disable-testing / --without-test configuration option but
can't find anything obvious.

Any ideas?

Thanks,
Chris

I think I mentioned this in response to an earlier message?  You need
to simply pre-seed that test: export bash_cv_have_mbstate_t=yes.  This
is a bug in readline's configure script that I need to get around to
fixing.

Thanks, yes you did mention this earlier.  I've now done this and
it builds successfully.
