build errors in unmodified unix/posix target

[Keith Robertson]

After configuring rtems-4.6.2 with the following line:

$ cd build-rtems
$ ../rtems-4.6.2/configure --enable-posix --disable-itron
--disable-networking --disable-cxx --prefix=/opt/rtems-4.6-posix

And then running 'make' from the build-rtems directory as more or less
suggested in:

http://www.rtems.com/onlinedocs/releases/rtemsdocs-4.6.2/share/rtems/html/started/started00060.html

I get the following errors:

As gcc thinks, these files appear not to exist in the location that gcc
is looking for them in.

~/work/build-rtems/posix$ cd
~/work/build-rtems/c/posix/tests/samples/fileio

~/work/build-rtems/c/posix/tests/samples/fileio$ ls
../../../../../posix/lib/include
bsp.h     chain.h     console.h  iosupp.h   rtc.h    serdbgcnf.h

filio.h  ioccom.h  ioctl.h  sockio.h  termios.h  ttycom.h


However, they do exist in:

~/work/rtems-4.6.2$ find -iname "ata.h"
./c/src/libchip/ide/ata.h
~/work/rtems-4.6.2$ find -iname "ide_ctrl.h"
./c/src/libchip/ide/ide_ctrl.h
~/work/rtems-4.6.2$ find -iname "dosfs.h" ./cpukit/libfs/src/dosfs/dosfs.h

It appears that fileio is just looking in the wrong place, however,
fixing this is currently out of the range of my understanding of the
rtems/autoconf/automake build system.  Before I dive into the
autoconf/automake manuals, does anybody have any suggestions?  Have I
missed something obvious?

Cheers,

Keith

P.S. Changing the appropriate source files to use an absolute path for
the above files seems to indicate that they are the correct ones.  The
test then appears to compile but fails while linking.  Seems to me there
is some larger configuration item missing than just the location of the
header files.
