-dnl Process this file with GNU Autoconf to produce a configure script. Then
-dnl call ./configure to create Makefiles. After that say make and make install.
-dnl See aclocal.m4 for additional self-made macros.
-dnl ===========================================================================
+dnl Process this file with autoconf to produce a configure script.
-dnl This file is used as a signal that everything is in place:
-AC_INIT(include/ginac.h)
-dnl A convenient header file for some additional system-dependend output:
-AC_CONFIG_HEADER(config.h)
+AC_INIT(ginac/basic.cpp)
+AM_CONFIG_HEADER(config.h)
+AC_PREREQ(2.12)
-dnl Set the Version Number at this place only:
-GiNaC_Major_Version=0
-GiNaC_Minor_Version=0
-GiNaC_Micro_Version=30
-dnl This composite variable can be inserted where it appears necessary:
-GiNaC_Version="${GiNaC_Major_Version}.${GiNaC_Minor_Version}.${GiNaC_Micro_Version}"
-dnl This composition is needed for libtool, if a shared lib shall be built:
-LibGiNaC_Ver="${GiNaC_Major_Version}:${GiNaC_Micro_Version}:${GiNaC_Minor_Version}"
-
-dnl ===========================================================================
-dnl Several features need to be added to standard-configure:
-dnl ===========================================================================
-AC_ARG_ENABLE(shared,
- [ --enable-shared build shared libraries [default=no]
- (a static library will still be built as well)],
- shared=${enableval}, shared="no")
+dnl This defines PACKAGE and VERSION
+AM_INIT_AUTOMAKE([GiNaC], [0.4])
+AM_MAINTAINER_MODE
dnl ===========================================================================
dnl Check for the compiler and all the utilities needed for the build:
dnl ===========================================================================
-dnl Which is the C++ Compiler? (whether to use c++, g++, gcc, CC, cxx, cc++...)
AC_PROG_CXX
-dnl How to run the C++ preprocessor?
AC_PROG_CXXCPP
+AM_PROG_INSTALL
+AM_PROG_LIBTOOL
+AM_PROG_LEX
+AC_PROG_YACC
+
dnl Switch to C++ language mode for the following libraries and headers:
AC_LANG_CPLUSPLUS
+
dnl Make sure the following libraries work by testing for symbols therein.
dnl They are automatically added the the variable $LIBS and thus passed into
dnl the Makefile:
AC_CHECK_LIB(stdc++, cout)
+
dnl Make sure all the necessary new-style headers are installed on the system.
dnl If one of them cannot be found the system is probably not ANSI-conform
dnl enough so trying the .h-style headers is a waste of time.
AC_CHECK_HEADERS(iostream vector map string list typeinfo iterator strstream stdexcept algorithm, ,
AC_MSG_ERROR(need to have ANSI compliant headers))
+
dnl We need to have Bruno Haible's CLN installed (macros are in aclocal.m4):
GINAC_CHECK_CLN_H
GINAC_CHECK_LIBCLN
-dnl We need to distribure install-sh anyways since otherwise configure will
-dnl refuse to do several things, like divert into subdirs and so:
-AC_PROG_INSTALL
-dnl Todd Brunhoff's makedepend utility is needed by make:
-AC_PATH_PROG(MAKEDEPEND, makedepend, "")
-dnl We need GNU libtool if the user chose to create a shared lib. (By using a
-dnl little trick we can safely recycle the variable shlib which is later passed
-dnl into the Makefile.)
-case "${shared}" in
-"yes"|"Yes"|"YES") # Default-enable ("yes") or user was nitpicking:
- shared="shlib";
- AC_PATH_PROG(LIBTOOL, libtool, "")

- shared="";
- fi

-dnl Check for helpers needed for building the GiNaC interactive shell:
-AC_PROG_LEX
-AC_PROG_YACC
-AC_DECL_YYTEXT
-AC_HEADER_STDC
+
+dnl Check for stuff needed for building the GiNaC interactive shell (ginsh):
AC_CHECK_HEADERS(unistd.h)
-AC_CHECK_FUNCS(strdup)
-AC_CHECK_HEADERS(readline/readline.h readline/history.h, , AC_MSG_ERROR(need to have GNU readline headers))
-AC_CHECK_LIB(readline, readline, , AC_MSG_ERROR(need to have GNU readline library))
+AC_REPLACE_FUNCS(strdup)
+AC_CHECK_HEADERS(readline/readline.h readline/history.h)
+AC_CHECK_LIB(readline, readline)
+
dnl Check for utilities needed by the different kinds of documentation.
dnl Documantation needs only be built when extending it, so never mind if it
dnl cannot find those helpers:
AC_PATH_PROG(JADE, jade, "")
AC_PATH_PROG(JADETEX, jadetex, "")
-dnl ===========================================================================
-dnl Substitute these variables in the Makefile:
-dnl ===========================================================================
-AC_SUBST(shared)
-AC_SUBST(LibGiNaC_Ver)

dnl ===========================================================================
dnl Produce a Makefile from Makefile.in:
dnl ===========================================================================
