Hi,
while cross-compiling gdbserver I'm getting the following error:

</log>

I've verified on the commandline that the problem is in the command segments of this type
-DSELECT_ARCHITECTURES='&bfd_arm_arch' (removing those archures.c compiles fine)

since the first pass compilation of gdb with using the host gcc compiles it without errors,
I assume the problem is related to the (third party) crosscompiler; is there any way to workaround
the problem?

thanx in advance,
Davide

You have some sort of mismatch between your build tools and your
shell.  Possibly the version of shell being used by the current
version of make.  I know that the compiler you reference is a native
Windows application rather than a Cygwin one; if something else
involved is native Windows it may be handling the quotes and ampersand
differently than expected.

Fortunately this is not a problem.  Run gdb/gdbserver/configure
instead of the top level configure script if all you need for the
target is gdbserver.

yes, the compiler war probably built on mingw32 (that is what the specs file
seems to say) and I'm on cygwin; I quickly tried to install and use mingw
for building gdb{server} but I get some other errors not worth investigating
ATM.

right, and it also works !
thanx a lot for your help, now it's time
to try it before getting back asking for more help:)
