Thanks for the followups. Rather than modify the code, my short-term workaround was to add "--disable-expat --with-expat=no" to the "extra gdb configure args" since the target in this particular case does not need XML support. Personally I think the answer is that, when building a static cross-gdb, expat should just always be built. -dp On Wed, Jun 5, 2013 at 7:22 AM, Bryan Hundven <bryanhundven@gmail.com> wrote: > Trevor, > > On 6/5/13 3:44 AM, "Trevor Woerner" <twoerner@gmail.com> wrote: > >>On Wed, Jun 5, 2013 at 4:18 AM, Bryan Hundven <bryanhundven@gmail.com> >>wrote: >>> On 6/4/13 10:28 PM, "Daniel Price" <daniel.price@gmail.com> wrote: >>>>This is on a system where libexpat-dev / -devel isn't installed. >>>> >>>>It seems to me that there's an issue where, despite requesting static >>>>cross-gdb, crosstool-ng >>>> is expecting libexpat to be on the host >>>>system >>> >>> There is definitely some funkyness with expat being needed to be built >>> here. >> >> >>Some target boards, such as the boards from ST, send their details >>(memory areas, register info, etc) to the host via XML (i.e. when >>using st-link).
