[maemo-developers] Find out OS version in configure script

Wed Apr 29 21:40:53 EEST 2009

Hi,

that's imho what maemo-version is there for. I use it this way:

  PKG_CHECK_EXISTS(maemo-version, [
    VERSION=`pkg-config --modversion maemo-version`
    AC_MSG_NOTICE([Configuring for Maemo $VERSION])
    CFLAGS="$CFLAGS -DMAEMO_VERSION=\\\"$VERSION\\\""
    MAJOR=`echo $VERSION | cut -b1 -`
    CFLAGS="$CFLAGS -DMAEMO_VERSION_MAJOR=$MAJOR"
  ], [
    AC_MSG_ERROR([maemo-version not found])
  ])

And in my program i can then do things like

#if MAEMO_VERSION_MAJOR == 5
  do_something();
#endif

Till
