Will try this with libisofs, too.

Where and/or how would i apply $top_srcdir ?

Well, now that i have instructions how to reproduce, i will look how
far i can get ... and whether i can grasp what's going on.

../configure obviously created version.h in ./build, not in in the
libisofs-1.5.0 directory, where it is ../version.h relative to ./libburn.

I tried to write in configure.ac:

  AC_CONFIG_FILES([
        ...
        $(top_srcdir)/version.h
        ...
  ])

but that yielded with ../configure

  ../configure: line 13383: top_srcdir: command not found
  [...]
  config.status: error: cannot find input file: `/version.h.in'

The first message does not appear if i omit the ()-brackets around
top_srcdir. But the second message remains.


Neither libburn nor libisoburn include version.h. I could try to change
the libisofs source accordingly.
But now i am curious how one would solve this problem while keeping version.h

Here i wonder why many other source files have
  #include "libisofs.h"
without causing this error.

The Makefile adds an -Ilibisofs for demo/demo, which is not added for
the library source files. But removing this does not change the error.
Changing it to
  -I../libisofs
does help. So again, i need to learn how to insert the top_srcdir.

(... and probably about the environmental differences between noinst_PROGRAMS
 and libisofs_libisofs_la_SOURCES. Somehow, demo/demo needs more -I than
 the libisofs/* sources.)

Please bear with me and don't hesitate to give me hints or instructions.


Have a nice day :)
