Hi Florian,

I would like to define macros containing the standard paths, like this:
#define BINDIR "@bindir@"
It does not work due to this code in lib/autoconf/general.m4 (which
appears to be predate DESTDIR support):
# Installation directory options.
# These are left unexpanded so users can "make install exec_prefix=/foo"
# and all the variables that are supposed to be based on exec_prefix
# by default will actually change.
# Use braces instead of parens because sh, perl, etc. also accept them.
# (The list follows the same order as the GNU Coding Standards.)
AC_SUBST([bindir], ['${exec_prefix}/bin'])dnl
AC_SUBST([sbindir], ['${exec_prefix}/sbin'])dnl
Is there are generally approved way to work around this? The manual
tells us to use -D preprocessor arguments, but I'd prefer the
explicitness of defining the macros via a header file.
I have the following in my Makefile.am, which I believe I borrowed from
the manual of autoconf or automake. BUILT_SOURCES makes the header file
be created before any compilation and CLEANFILES makes the header file
be removed by 'make clean'.
CLEANFILES += configmake.h
BUILT_SOURCES += configmake.h
configmake.h: Makefile
echo '#define BINDIR "$(bindir)"' >$@
Cheers,
Peter
Thanks,
