More precisely "make check" is broken for out of tree builds, although
the core reason is not restricted to "make check". It was observed after
r1909334 / r1909335, which introduce a dependency on
arch/unix/apr_private.h to testpoll.c.
The header file arch/unix/apr_private.h (build tree) is generated from
arch/unix/apr_private.h.in (source tree). But is contains
#include "../apr_private_common.h"
which will be looked up due to the relative path in the build tree, but
actually is located in the source tree.
Currently arch/unix/apr_private.h is only used in testpoll.h, therefore
the problem only shows up during make check. But in fact
arch/unix/apr_private.h is broken for any potential use.
This problem is in 1.7.x and 1.8.x. I did not check apr trunk.
Unfortunately I have no idea how to make autoheader to use
#include "arch/apr_private_common.h"
instead of
#include "../apr_private_common.h"
in the generated arch/unix/apr_private.h.in.
Maybe someone has an idea?
Thanks and regards,
Rainer
