TEA_PREFIX

# 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

#-----------------------------------------------------------------------
# Specify the C source files to compile in TEA_ADD_SOURCES,
# public headers that need to be installed in TEA_ADD_HEADERS,
# stub library C source files to compile in TEA_ADD_STUB_SOURCES,
# and runtime Tcl library files in TEA_ADD_TCL_SOURCES.
# This defines PKG(_STUB)_SOURCES, PKG(_STUB)_OBJECTS, PKG_HEADERS
# and PKG_TCL_SOURCES.

# 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

#--------------------------------------------------------------------
# For Unix/Tk builds, make sure that the X libraries/headers are found.
# This must be called after TEA_CONFIG_CFLAGS as it adjusts LIBS.
#--------------------------------------------------------------------

# See [Bug #82910]
#TEA_PATH_X

#--------------------------------------------------------------------
# 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)

#--------------------------------------------------------------------
# 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

#--------------------------------------------------------------------
# __CHANGE__
# Add platform libs to LIBS or SHLIB_LD_LIBS as necessary.
#--------------------------------------------------------------------

SHLIB_LD_LIBS="${SHLIB_LD_LIBS} \${TCL_LIBS}"

#--------------------------------------------------------------------
# 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.

# Finally, substitute all of the various values into the Makefile.
# You may alternatively have a special pkgIndex.tcl.in or other files
