AC_SUBST problem (was: Build error...)

[Etienne M. Gagnon]

Hi again.

I have nailed down the problem to AC_SUBST calls in configure.ac

Apparently the following does not work:

--- BEGIN ---
PACKAGE="sablevm"
VERSION="0.1.6"
LIBVERSION="0:6:0"

AC_INIT(${PACKAGE}, ${VERSION}, ${BUG-REPORT-ADDRESS})
AC_CONFIG_SRCDIR([src/sablevm/sablevm.c])

AC_SUBST(PACKAGE)
AC_SUBST(VERSION)
AC_SUBST(LIBVERSION)
...
--- END ---

The following does not work either:

--- BEGIN ---
PACKAGE="sablevm"
VERSION="0.1.6"
LIBVERSION="0:6:0"

AC_INIT(${PACKAGE}, ${VERSION}, ${BUG-REPORT-ADDRESS})
AC_CONFIG_SRCDIR([src/sablevm/sablevm.c])

AC_SUBST(PACKAGE, ${PACKAGE})
AC_SUBST(VERSION, ${VERSION})
AC_SUBST(LIBVERSION, ${LIBVERSION})
...
--- END ---

But, the following works:

--- BEGIN ---
PACKAGE="sablevm"
VERSION="0.1.6"
BUG-REPORT-ADDRESS="http://www.sablevm.org/";
LIBVERSION="0:6:0"

AC_INIT(${PACKAGE}, ${VERSION}, ${BUG-REPORT-ADDRESS})
AC_CONFIG_SRCDIR([src/sablevm/sablevm.c])

AC_SUBST(PACKAGE, [sablevm])
AC_SUBST(VERSION, [0.1.6])
AC_SUBST(LIBVERSION, [0:6:0])
...
--- END ---

The problem is that I do not like the duplication.  I thought using
AC_SUBST caused the evaluation of shell variables.  Maybe I am missing
an important point.  So, I will redirect this problem to the autoconf
list, but feel free to help me, if you have any good advice.

Thanks,

Etienne
