# Configure script for package 'memchan', as distributed at November 20, 2001.
# TEA compliant.

# find the sources.  The argument to AC_INIT is a unique filename for
# this package.

# Standard compiler checks.
# This sets up CC by using the CC env var, or looks for gcc otherwise.
# This also calls AC_PROG_CC, AC_PROG_INSTALL and a few others to create
# the basic setup necessary to compile executables.

TEA_SETUP_COMPILER

# __CHANGE__
# Choose which headers you need.  Extension authors should try very
# hard to only rely on the Tcl public header files.  Internal headers
# contain private data structures and are subject to change without
# notice.

# A few miscellaneous platform-specific items:
#
# We have to define a special symbol for Windows (BUILD_Memchan in this
# case) so that we create the export library with the dll.
#
# Windows creates a few extra files that need to be cleaned up.
# We can add more files to clean if our extension creates any extra
# files in the future.
#
# Define any extra compiler flags in the PACKAGE_CFLAGS variable.
# These will be appended to the current set of compiler flags for
# your system.

TEA_ENABLE_THREADS

#--------------------------------------------------------------------
# The statement below defines a collection of symbols related to
# building as a shared library instead of a static library.
#--------------------------------------------------------------------

TEA_ENABLE_SHARED

#--------------------------------------------------------------------
# This macro figures out what flags to use with the compiler/linker
# when building shared/static debug/optimized objects.  This information
# can be taken from the tclConfig.sh file, but this figures it all out.
#--------------------------------------------------------------------

TEA_CONFIG_CFLAGS

#--------------------------------------------------------------------
# Set the default compiler switches based on the --enable-symbols option.
#--------------------------------------------------------------------

TEA_ENABLE_SYMBOLS

#--------------------------------------------------------------------
# Everyone should be linking against the Tcl stub library.  If you
# can't for some reason, remove this definition.  If you aren't using
# stubs, you also need to modify the SHLIB_LD_LIBS setting below to
# link against the non-stubbed Tcl library.
#--------------------------------------------------------------------

AC_DEFINE(USE_TCL_STUBS)

#--------------------------------------------------------------------
# If ltoa is present, use it to convert integer values into strings.
# If not, sprintf is used, which is slower and requires more code.
#--------------------------------------------------------------------

AC_CHECK_FUNCS(ltoa)

#--------------------------------------------------------------------
# This macro generates a line to use when building a library.  It
# depends on values set by the TEA_ENABLE_SHARED, TEA_ENABLE_SYMBOLS,
# and TEA_LOAD_TCLCONFIG macros above.
#--------------------------------------------------------------------

TEA_MAKE_LIB

#--------------------------------------------------------------------
# Find tclsh so that we can run pkg_mkIndex to generate the pkgIndex.tcl
# file during the install process.  Don't run the TCLSH_PROG through
# ${CYGPATH} because it's being used directly by make.
# Require that we use a tclsh shell version 8.2 or later since earlier
# versions have bugs in the pkg_mkIndex routine.
# Add WISH as well if this is a Tk extension.
#--------------------------------------------------------------------

TEA_PROG_TCLSH

#--------------------------------------------------------------------
# Finally, substitute all of the various values into the Makefile.
# You may alternatively have a special pkgIndex.tcl.in or other files
# which require substituting th AC variables in.  Include these here.
