I'm trying to create a recipe for OpenDDS. The recipe works so far as
fetching, unpacking, and configuration. Or it seems to. :) Part of the
configuration piece is that it also pulls down ACE+TAO real-time CORBA.
This part works fine as well.

I set S as follows to match the unpacking directories enforced by the
tar file:


The package comes with a configuration script pre-built, and it expects
to be told where glibc is. So, I write do_configure as follows:


do_configure() {
${S}/configure ${EXTRA_OECONF}

The problem that I run into is during compilation. I write the following
for do_compile()

do_compile() {
oenote ${STAGING_DIR}
cd ${S} && make
Is there a reason you are overriding configure and compile? These appear
to be autoconf projects, which should just work for recipes using

This works right up until there is a compile error in ACE+TAO. Of
course, I build the entire DDS package, including ACE+TAO, with no
hiccups in Ubuntu, so I understand that this is a
cross-compile/environment issue.

The compile error is that it cannot find features.h, which is clearly in
${STAGING_LIBDIR}/${MACHINE}/usr/include. The compile command which is
being executed is as follows (this is going to be ugly, let me know if
there's a better way to include this, such as a pastebin somewhere):
This is better - the pastebin isn't as reliable, and having it inline to
review and for future reference is much preferred.

The thing that is puzzling me is that --sysroot seems to be pointing in
the general direction of ${STAGING_DIR} and so the include directive,
#include <features.h> should be good. I have checked, and features.h is
in the /usr/include subdirectory there.
I see unistd.h missing, not features.h.


Does anyone have a clue they could lend me?
