# The build process allows for using a cross-compiler. But the default
|
|
# action is to target the same platform that we are running on. The
|
|
# configure script needs to discover the following properties of the
|
|
# build and target systems:
|
|
#
|
|
# srcdir
|
|
#
|
|
# The is the name of the directory that contains the
|
|
# "configure" shell script. All source files are
|
|
# located relative to this directory.
|
|
#
|
|
# bindir
|
|
#
|
|
# The name of the directory where executables should be
|
|
# written by the "install" target of the makefile.
|
|
#
|
|
# program_prefix
|

#
|

# Add this prefix to the names of all executables that run

|
# target platform. In other words, the cross-compiler.
|
|
#
|
|
# TARGET_CFLAGS
|

#
|

# into *.o files. Do not include TARGET_TCL_INC in this list.

|
|
# constructing and installing the TCL extension.
|
|
#
|
|
# TARGET_READLINE_LIBS
|
|
#
|
|
# This is the library directives passed to the target linker
|
|
# that cause the executable to link against the readline library.
|
|
# This might be a switch like "-lreadline" or pathnames of library
|

# file like "../../src/libreadline.a".

|
|
# by TARGET_CC into executables for the target platform.
|
|
#
|
|
# TARGET_LIBS
|
|
#
|

# TARGET_READLINE_LIBS, etc.
|
|
#
|
|
# TARGET_EXEEXT

#
|
|
# The filename extension for executables on the

#
|
|
# The generated configure script will make an attempt to guess
|

|
# the guesses by setting the environment variable named
|

# "config_AAAA" where "AAAA" is the name of the parameter
|
|
# described above. (Exception: srcdir cannot be set this way.)

# If you have a file that sets one or more of these environment

#
|
|
# configure --with-hints=FILE
|
|
#
|
|
# where FILE is the name of the file that sets the environment
|
|
# variables. FILE should be an absolute pathname.
|
|
#
|
|
# This configure.in file is easy to reuse on other projects. Just
|
|
# change the argument to AC_INIT(). And disable any features that
|
|
