That's strange because other C++ libraries (I've tested some - libds for
example) use AC_PROG_LIBTOOL macro call too and configure doesn't make those
strange checks later.
Here is my configure.in:
AC_INIT(deflatec++, 1.00)
AM_INIT_AUTOMAKE
AC_LANG(C++)
AC_PROG_CXX
AC_PROG_INSTALL
CXXFLAGS="-ansi -pedantic -Wall ${CXXFLAGS}"
AC_PROG_LIBTOOL
AC_OUTPUT(Makefile src/Makefile)
And here is libds's configure.in (a few first lines):
nl Process this file with autoconf to produce a configure script.
AC_INIT(lib/DSNetwork.cpp) dnl a source file from your sub dir
AC_PREFIX_DEFAULT(/usr/local)
AC_CONFIG_HEADER(config.h) dnl at the distribution this done
AC_CHECK_LIB(socket, socket, [LIBSOCKET="-lsocket -lnsl"]) dnl for Solaris
AC_SUBST(LIBSOCKET)
AC_ARG_WITH(warnings,
[ --with-warnings compile with -pedantic -ansi -Wall],
[if test "$withval" = "yes"; then CXXFLAGS="$CXXFLAGS -ansi -pedantic -Wall";
CFLAGS="$CFLAGS -ansi -pedantic -W
all"; fi])
AC_PROG_CXX
AC_PROG_INSTALL
AC_PROG_LIBTOOL
AC_HEADER_STDC
[...]
Besides some checks (socket, arg etc) there is almost no difference, but libds
configure doesn't check for fortran compiler and other unnecessary stuff.
