dnl This file is part of the FreeType project.
dnl
dnl Process this file with autoconf to produce a configure script.
dnl
dnl This file must be processed from the top FreeType 2 directory. E.g:
dnl
dnl % autoconf config/unix/configure.in > config/unix/configure
dnl
AC_INIT(ftconfig.in)
cnl Configuration file - stay in 8.3 limit
AC_CONFIG_HEADER(ftconfig.h:ftconfig.in)
dnl Due to a bug in autoconf we must set $srcdir explicitly to an absolute
dnl path.
srcdir=`pwd`
dnl Checks for system type.
AC_CANONICAL_SYSTEM
dnl Checks for programs.
AC_PROG_CC

AC_PROG_LN_S
dnl Checks for libraries.

AC_LIBRARY_NET
dnl Checks for header files.
AC_PATH_XTRA
AC_CHECK_HEADERS(stdlib.h fcntl.h unistd.h)

AC_CHECK_SIZEOF(long)
dnl Checks for library functions.
dnl Here we check whether we can use our mmap file component.

AM_PROG_LIBTOOL
dnl Another bug: to make --srcdir work correctly we have to create the
dnl directory hierarchy first since autoconf only uses mkdir.
dnl $srcdir/config/unix/mkinstalldirs lib/arch/unix test/arch/unix
dnl Create the Unix-specific sub-Makefile "config/unix/unix.mk" that will be
dnl used by the build system..
