1.1 misho 1: #
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:
6: #
7: # srcdir
8: #
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.
12: #
13: # bindir
14: #
15: # The name of the directory where executables should be
16: # written by the "install" target of the makefile.
17: #
18: # program_prefix
19: #
20: # Add this prefix to the names of all executables that run
21: # on the target machine. Default: ""
22: #
23: # ENABLE_SHARED
24: #
25: # True if shared libraries should be generated.
26: #
27: # BUILD_CC
28: #
29: # The name of a command that is used to convert C
30: # source files into executables that run on the build
31: # platform.
32: #
33: # BUILD_CFLAGS
34: #
35: # Switches that the build compiler needs in order to construct
36: # command-line programs.
37: #
38: # BUILD_LIBS
39: #
40: # Libraries that the build compiler needs in order to construct
41: # command-line programs.
42: #
43: # BUILD_EXEEXT
44: #
45: # The filename extension for executables on the build
46: # platform. "" for Unix and ".exe" for Windows.
47: #
48: # TCL_*
49: #
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.
53: #
54: # TARGET_READLINE_LIBS
55: #
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".
60: #
61: # TARGET_READLINE_INC
62: #
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.
66: #
67: # TARGET_EXEEXT
68: #
69: # The filename extension for executables on the
70: # target platform. "" for Unix and ".exe" for windows.
71: #
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:
79: #
80: # configure --with-hints=FILE
81: #
82: # where FILE is the name of the file that sets the environment
83: # variables. FILE should be an absolute pathname.
84: #
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
88: # the corresponding code.
