ad dnl Process this file with autoconf to produce a configure script. dnl The ONLY thing this is used for is to configure for different dnl linux architectures and configurations, it is not used to make the dnl code more portable dnl You MUST have an environment that has all the POSIX functions and dnl some of the more populare bsd/sysv ones (like select). You'll also dnl need a C++ compiler that is semi-standard conformant, exceptions are dnl not used but STL is. dnl 'make -f Makefile startup' will generate the configure file from dnl configure.in correctly and can be run at any time AC_INIT(configure.in) AC_CONFIG_AUX_DIR(buildlib) AC_CONFIG_HEADER(include/config.h:buildlib/config.h.in) dnl -- SET THIS TO THE RELEASE VERSION -- AC_DEFINE_UNQUOTED(VERSION,"0.3.19") AC_DEFINE_UNQUOTED(PACKAGE,"apt") dnl Check our C compiler AC_CHECK_TOOL_PREFIX AC_PROG_CC AC_ISC_POSIX dnl Check the host arch (build+target not needed... yet) AC_CANONICAL_HOST AC_CHECK_TOOL_PREFIX dnl recheck, in case the initial guess was wrong dnl Check for other programs AC_PROG_CXX AC_PROG_CPP AC_PROG_RANLIB AC_CHECK_TOOL(AR,ar,"ar") dnl Checks for sockets SAVE_LIBS="$LIBS" LIBS="" AC_SEARCH_LIBS(gethostbyname,nsl) AC_SEARCH_LIBS(connect,socket) SOCKETLIBS="$LIBS" AC_SUBST(SOCKETLIBS) LIBS="$SAVE_LIBS" dnl Section Disabled pending removal of deity widget library -- jgg if test "yes" != "yes"; then dnl Checks for X11 AC_PATH_X AC_PATH_XTRA AC_SUBST(X11LIB) X11LIB= if test "$no_x" != "yes"; then X11LIB="-lX11" AC_DEFINE(HAVE_X11) dnl Checks for ZPM AC_CHECK_LIB(Xpm, XpmLibraryVersion,[AC_DEFINE(HAVE_LIBXPM) XPMLIB="-lXpm"],,$X_LIBS $X_PRE_LIBS $X11LIB $X_EXTRA_LIBS) AC_SUBST(XPMLIB) if test "$XPMLIB" != "-lXpm"; then AC_MSG_ERROR(failed: I need xpm if you are building for X) fi fi dnl Checks for Slang AC_CHECK_LIB(slang, SLang_Version,[AC_DEFINE(HAVE_LIBSLANG) SLANGLIB="-lslang"]) AC_SUBST(SLANGLIB) dnl Checks for GPM AC_ARG_WITH(gpm,[ --without-gpm do not use GPM mouse support]) if test "$with_gpm" != "no"; then AC_CHECK_LIB(gpm, Gpm_Open,[AC_DEFINE(HAVE_LIBGPM) GPMLIB="-lgpm"]) AC_SUBST(GPMLIB) fi fi dnl Checks for pthread #AC_CHECK_LIB(pthread, pthread_create,[AC_DEFINE(HAVE_PTHREAD) PTHREADLIB="-lpthread"]) AC_SUBST(PTHREADLIB) #if test "$PTHREADLIB" != "-lpthread"; then # AC_MSG_ERROR(failed: I need posix threads, pthread) #fi dnl Converts the ARCH to be the same as dpkg AC_MSG_CHECKING(system architecture) archset="`awk \"{ if(\\\$1 == \\\"$host_cpu\\\") print \\\$2 }\" $srcdir/buildlib/archtable`" if test "x$archset" = "x"; then AC_MSG_ERROR(failed: use --host=) fi AC_MSG_RESULT($archset) AC_DEFINE_UNQUOTED(ARCHITECTURE,"$archset") dnl We use C9x types if at all possible AC_CACHE_CHECK([for C9x integer types],c9x_ints,[ AC_TRY_COMPILE([#include ], [uint8_t Foo1;uint16_t Foo2;uint32_t Foo3;], c9x_ints=yes,c9x_ints=no)]) dnl Single Unix Spec statvfs AC_CHECK_FUNC(statvfs,[HAVE_STATVFS=yes]) AC_SUBST(HAVE_STATVFS) dnl Arg, linux and bsd put their statfs function in different places if test x"$HAVE_STATVFS" != x"yes"; then AC_EGREP_HEADER(statfs,sys/vfs.h,[AC_DEFINE(HAVE_VFS_H)],[ AC_EGREP_HEADER(statfs,sys/mount.h,[AC_DEFINE(HAVE_MOUNT_H)],[AC_MSG_ERROR(failed: Need statvfs)]) ]) fi dnl Check the sizes etc. of the architecture dnl This is stupid, it should just use the AC macros like it does below dnl Cross compilers can either get a real C library or preload the cache dnl with their size values. changequote(,) archline="`grep \"^$archset\" $srcdir/buildlib/sizetable | cut -f 2- -d ' '`" if test "x$archline" != "x"; then changequote([,]) set $archline if test "$1" = "little"; then ac_cv_c_bigendian=no else ac_cv_c_bigendian=yes fi size_char=$2 size_int=$3 size_short=$4 size_long=$5 fi dnl I wonder what AC_C_BIGENDIAN does if you cross compile... if test "$cross_compiling" = "yes" -a "x$archline" = "x"; then AC_MSG_ERROR(When cross compiling, architecture must be present in sizetable) fi AC_C_BIGENDIAN dnl We do not need this if we have inttypes!
