missing dependency on expat-native in gdb-cross-sdk-7.1-r7.0

[Jonathan Cameron]

Hi all,

Got the following error from log.do_compile when building meta-toolchain with angstrom-2010.x using latest testing-next.

gcc: /mnt/disk2/buildroot/oe/oe-stable/tmp/sysroots/x86_64-linux/usr/lib/libexpat.a: No such file or directory
make[2]: *** [gdb] Error 1
make[2]: Leaving directory `/mnt/disk2/buildroot/oe/oe-stable/tmp/work/x86_64-armv5te-sdk-angstrom-linux-gnueabi/gdb-cross-sdk-7.1-r7.0/build-arm-angstrom-linux-gnueabi/gdb'
make[1]: *** [all-gdb] Error 2
make[1]: Leaving directory `/mnt/disk2/buildroot/oe/oe-stable/tmp/work/x86_64-armv5te-sdk-angstrom-linux-gnueabi/gdb-cross-sdk-7.1-r7.0/build-arm-angstrom-linux-gnueabi'
make: *** [all] Error 2
FATAL: oe_runmake failed

I'd suggest adding expat-native to gdb-cross-sdk.inc DEPENDS (which seems to fix the problem) No idea if it is needed
for all versions though.

Thanks,

Jonathan

At least GDB 7.x needs expat to parse the register definitions for the CPU.
E.g. this is important when using the gdb remote protocol.

You should also pass --with-expat to it, right now I have a build issue with
the target gdb and this argument.

Ah, thanks for the heads up. I'll try that and see how I get on.

As an aside there is also an issue with both binutils-cross-sdk and gdb-cross-sdk
wanting to install libiberty.a

Yeah, I've run into this.

But more is needed, as other gdb variants clobber other binutils libs too.
