2 # The build process allows for using a cross-compiler. But the default
3 # action is to target the same platform that we are running on. The
4 # configure script needs to discover the following properties of the
5 # build and target systems:
9 # The is the name of the directory that contains the
10 # "configure" shell script. All source files are
11 # located relative to this directory.
15 # The name of the directory where executables should be
16 # written by the "install" target of the makefile.
20 # Add this prefix to the names of all executables that run
21 # on the target machine. Default: ""
25 # True if shared libraries should be generated.
29 # The name of a command that is used to convert C
30 # source files into executables that run on the build
35 # Switches that the build compiler needs in order to construct
36 # command-line programs.
40 # Libraries that the build compiler needs in order to construct
41 # command-line programs.
45 # The filename extension for executables on the build
46 # platform. "" for Unix and ".exe" for Windows.
50 # Lots of values are read in from the tclConfig.sh script,
51 # if that script is available. This values are used for
52 # constructing and installing the TCL extension.
54 # TARGET_READLINE_LIBS
56 # This is the library directives passed to the target linker
57 # that cause the executable to link against the readline library.
58 # This might be a switch like "-lreadline" or pathnames of library
59 # file like "../../src/libreadline.a".
63 # This variables define the directory that contain header
64 # files for the readline library. If the compiler is able
65 # to find <readline.h> on its own, then this can be blank.
69 # The filename extension for executables on the
70 # target platform. "" for Unix and ".exe" for windows.
72 # The generated configure script will make an attempt to guess
73 # at all of the above parameters. You can override any of
74 # the guesses by setting the environment variable named
75 # "config_AAAA" where "AAAA" is the name of the parameter
76 # described above. (Exception: srcdir cannot be set this way.)
77 # If you have a file that sets one or more of these environment
78 # variables, you can invoke configure as follows:
80 # configure --with-hints=FILE
82 # where FILE is the name of the file that sets the environment
83 # variables. FILE should be an absolute pathname.
85 # This configure.in file is easy to reuse on other projects. Just
86 # change the argument to AC_INIT(). And disable any features that
87 # you don't need (for example BLT) by erasing or commenting out
