[Crrcsim-devel] Autoconf

[<a_r...@gm...>]

Hi!

Just in case, someone wants to contribute...

IIRC, the list does not like attachments, so configure.ac just inline:
==========
dnl First attempt to create a GNU auto* tools scheme for CRRC
dnl Sep 1 2007
dnl Jan Reucker <slo...@gm...>
dnl Andreas Rueckert <ma...@an...>


dnl Init the autoconf macros
AC_INIT(crrc-config, version-0.1)

dnl Init automake
AM_INIT_AUTOMAKE

dnl This project is written in C++
AC_LANG(C++)

dnl check for required libs

dnl Search for a portaudio lib

dnl Default is: no portaudio present
portaudio=0

dnl Check for Portaudio 18
AC_CHECK_LIB( portaudio, Pa_CountDevices, [portaudio=18], [])

dnl Check for Portaudio 19
AC_CHECK_LIB( portaudio, Pa_GetDeviceCount, [portaudio=19], [])

dnl Show the result
if test $portaudio == 18
then
  AC_MSG_NOTICE([Portaudio 18 found])
else if test $portaudio == 19
  then
    AC_MSG_NOTICE([Portaudio 19 found])
  else
    AC_MSG_NOTICE([No Portaudio found])
  fi
fi

dnl Search for SDL 1.2.x

SDL_VERSION=1.2.0
AM_PATH_SDL($SDL_VERSION,:,AC_MSG_ERROR([*** SDL version $SDL_VERSION not found!])
)
AM_CFLAGS="$AM_CFLAGS $SDL_CFLAGS"
AM_LDFLAGS="$AM_LDFLAGS $SDL_LIBS"

dnl Search for GLUT 3.7.x
AX_CHECK_GLUT



dnl Search for PLIB 1.8.4
dnl PLIB consist of several more or less independent
dnl components, so we better check each component we need.
AC_CHECK_HEADER(plib/ul.h)
AC_CHECK_HEADER(plib/sg.h)
AC_CHECK_HEADER(plib/ssg.h)
AC_CHECK_HEADER(plib/ssgaSky.h)
AC_CHECK_HEADER(plib/pu.h)
AC_CHECK_HEADER(plib/puAux.h)
if  (test "x$ac_cv_header_plib_puAux_h" != "xyes")    \
 || (test "x$ac_cv_header_plib_pu_h" != "xyes")       \
 || (test "x$ac_cv_header_plib_ssgaSky_h" != "xyes")  \
 || (test "x$ac_cv_header_plib_ssg_h" != "xyes")      \
 || (test "x$ac_cv_header_plib_sg_h" != "xyes")       \
 || (test "x$ac_cv_header_plib_ul_h" != "xyes"); then
    echo
    echo "You *must* have the plib library installed on your system to build CRRC!"
    echo
    echo "configure aborted."
    exit
fi

dnl Thanks to the FlightGear guys for this piece of code...
AC_MSG_CHECKING([for plib 1.8.4 or newer])
AC_TRY_RUN([
#include <plib/ul.h>

#define MIN_PLIB_VERSION 184

int main() {
    if ( PLIB_VERSION < MIN_PLIB_VERSION ) {
         return -1;
    }

    return 0;
}
],
  AC_MSG_RESULT(yes),
  [AC_MSG_RESULT(wrong version);
   AC_MSG_ERROR([Install plib 1.8.4 or later first...])],
  AC_MSG_RESULT(yes)
)

AC_CONFIG_FILES([Makefile])

AC_OUTPUT
==========

If you want to test this, drop me a note, since you a m4 dir. Jan tagged
this status in CVS and created a tarball.

The heli stuff is somewhat more complicated, so I guess a CVS branch would be
the better alternative to work on it...

Ciao,
Andreas
