Hi all. I'm starting to use autoconf version 2.13 (Debian testing package), and would like that it tells me whether the iostream headers are installed or not. My configure.in is:
<--------------- configure.in ------------->
# -*- Autoconf -*- # Process this file with autoconf to produce a configure script.
AC_PREREQ(2.57) AC_INIT([Foo Library], [1.0], [Ramón <me@xxxxxxxxxx>]) AC_CONFIG_SRCDIR([src/Exception.h]) AC_CONFIG_AUX_DIR([./aux-build-tools])
AC_CONFIG_HEADER([config.h])
# Where to install the things AC_SUBST(prefix, "/tmp/test")
# Only if you are not writting Makefile.in by hand # We get Makefile.in from Makefile.am AM_INIT_AUTOMAKE
# Checks for programs. AC_PROG_CXX AC_PROG_CXXCPP AC_PROG_RANLIB AC_PROG_INSTALL
# Checks for header files. AC_PATH_X AC_HEADER_STDC AC_CHECK_HEADERS([malloc.h stdlib.h]) AC_CHECK_HEADERS([iostream])
# Checks for typedefs, structures, and compiler characteristics. AC_HEADER_STDBOOL AC_C_CONST AC_C_INLINE AC_TYPE_SIZE_T
# Checks for library functions. AC_CHECK_FUNCS([floor memset pow sqrt])
AC_CONFIG_FILES([Makefile]) AC_OUTPUT
<--------------- end of configure.in ------------->
When I do
$ autoreconf && ./configure
I get (I haven't written the Makefile.in yet, but I think it does not have to do with the problem):
<--------------- stdout ------------->

<--------------- end of stdout ------------->
The problem, I believe, is that I get
checking iostream usability... no checking iostream presence... no checking for iostream... no
but I have it
$ ls /usr/include/c++/3.3/iostream -l -rw-r--r-- 1 root root 3,0K 2003-11-12 10:56 /usr/include/c++/3.3/iostream
and the compiler seems happy with this example:
I have this code snippet:
/* * test.cpp */
#include <iostream>
int main()
{
std::cout << "Hello World!" << std::endl;
return 0;
}and can compile it with $ g++ -o test test.cpp and run it $ ./test Hello World!
where
$ g++ --version g++ (GCC) 3.3.2 (Debian)
I have also tried with
AC_CHECK_HEADERS([c++/3.3/iostream])
and
AC_CHECK_HEADERS([/usr/include/c++/3.3/iostream])
but it doesn't work. Am I trying to do something that cannot be done, or in a wrong way?
Cheers,
Ramón.
