Given this from your

Add a line like this to


or simply:

  AM_CFLAGS = -ansi -pedantic -Wall

Note that it's usually unwise to add such flags unconditionally; many compilers
do not support them.

Adding such a line is generally correct.  It sounds as though the headers do not
exist under the names you call them from  If you do generate these
headers during your build process, look at documentation for BUILT_SOURCES in
the GNU Automake manual.

If none of that seems to apply, please post a with your
include_HEADERS line and also the build error that arises with it.
