dnl Checks for libraries.
AC_CHECK_LIB(dl, dlopen)
dnl
dnl autoconf is too weak to check for tcl/tk in the obvious ways:
dnl 1) you need to search for tcl and tcl80 and tcl76..., not just one name
dnl 2) you need to search in lots of yucky places.
dnl instead we use a per-host check below
dnl
dnl builtin(include, ./conf/configure.in.tcl)
dnl builtin(include, ./conf/configure.in.tk)

dnl
dnl Checks for header files.
dnl check tcl/tk later
dnl
dnl AC_HAVE_HEADERS(tcl.h tk.h)

dnl tcl/tk bother because FreeBSD makes things hard by putting versions
dnl in things.
AC_ARG_WITH(tcl-ver, --with-tcl-ver=VERSION specify the version of tcl/tk, TCL_VERS=$withval, TCL_VERS=8.3.1)
TCL_DOTTED_HI_VERS=`echo $TCL_VERS | sed "s/\([[^\.]]*\)\.\([[^\.]]*\).*/\1.\2/"`
TCL_NODOT_HI_VERS=`echo $TCL_DOTTED_HI_VERS | sed "s/\.//g"`
AC_ARG_WITH(tk-ver, --with-tk-ver=VERSION specify the version of tcl/tk, TK_VERS=$withval, TK_VERS=8.3.1)
TK_DOTTED_HI_VERS=`echo $TK_VERS | sed "s/\([[^\.]]*\)\.\([[^\.]]*\).*/\1.\2/"`
TK_NODOT_HI_VERS=`echo $TK_DOTTED_HI_VERS | sed "s/\.//g"`

AC_ARG_WITH(tcltk-lib-suffix-type, --with-tcltk-lib-suffix-type=TYPE where TYPE is either none/nodot/dot, TCLTK_LIB_SUFFIX_TYPE=$withval,TCLTK_LIB_SUFFIX_TYPE="unspecified")
