= How to build ruby using Visual C++

== Requirement

(1) Visual C++ 5.0 or later.

(2) Please set environment variable (({INCLUDE})), (({LIB})), (({PATH}))
    to run required commands properly from the command line.

    Note: building ruby requires following commands.
     * nmake
     * cl
     * lib
     * dumpbin

(3) If you want to build from CVS source, following commands are required.
     * bison
     * sed

== How to compile and install

(1) Execute win32\configure.bat on your build directory.
    You can specify the target platform as an argument.
    For example, run `((%configure i686-mswin32%))'
    You can also specify the install directory.
    For example, run `((%configure --prefix=<install_directory>%))'
    Default of the install directory is /usr .

(2) Change ((|RUBY_INSTALL_NAME|)) and ((|RUBY_SO_NAME|)) in (({Makefile}))
    if you want to change the name of the executable files. 
    And add ((|RUBYW_INSTALL_NAME|)) to change the name of the
    executable without console window if also you want.

(3) Run `((%nmake%))'

(4) If you want to make rubyw.exe, run `((%nmake rubyw.exe%))'

(5) Run `((%nmake test%))'

(6) Run `((%nmake install%))'

    This command will create following directories and install files onto them.
      * <install_directory>\bin
      * <install_directory>\lib
      * <install_directory>\lib\ruby
      * <install_directory>\lib\ruby\<MAJOR>.<MINOR>
      * <install_directory>\lib\ruby\<MAJOR>.<MINOR>\<PLATFORM>
      * <install_directory>\lib\ruby\site_ruby
      * <install_directory>\lib\ruby\site_ruby\<MAJOR>.<MINOR>
      * <install_directory>\lib\ruby\site_ruby\<MAJOR>.<MINOR>\<PLATFORM>
      * <install_directory>\man\man1
    If Ruby's version is `x.y.z', the ((|<MAJOR>|)) is `x' and the ((|<MINOR>|)) is `y'.
    The default ((|<PLATFORM>|)) is `(({i386-mswin32}))'.

== Icons

Any icon files(*.ico) in the build directory, directories specified with
((|icondirs|)) make variable and (({win32})) directory under the ruby
source directory will be included in DLL or executable files, according
to their base names.
    $(RUBY_INSTALL_NAME).ico or ruby.ico   --> $(RUBY_INSTALL_NAME).exe
    $(RUBYW_INSTALL_NAME).ico or rubyw.ico --> $(RUBYW_INSTALL_NAME).exe
    the others                             --> $(RUBY_SO_NAME).dll

Although no icons are distributed with the ruby source or in the official 
site, you can use anything you like. For example, followings are written 
in Japanese, but you can download at least.

  ((<zipped icons|URL:http://member.nifty.ne.jp/ueivu/Ruby_ico.zip>))
* ((<URL:http://homepage1.nifty.com/a_nakata/ruby/>)) or
  ((<icon itself|URL:http://homepage1.nifty.com/a_nakata/ruby/RubyIcon.ico>))

== Build examples

* Build on the ruby source directory.

  ex.)
    ruby source directory:  C:\ruby
    build directory:        C:\ruby
    install directory:      C:\usr\local

    C:
    cd \ruby
    win32\configure --prefix=/usr/local
    nmake
    nmake test
    nmake install

* Build on the relative directory from the ruby source directory.

  ex.)
    ruby source directory:  C:\ruby
    build directory:        C:\ruby\mswin32
    install directory:      C:\usr\local

    C:
    cd \ruby
    mkdir mswin32
    cd mswin32
    ..\win32\configure --prefix=/usr/local
    nmake
    nmake test
    nmake install

* Build on the different drive.

  ex.)
    ruby source directory:  C:\src\ruby
    build directory:        D:\build\ruby
    install directory:      C:\usr\local

    D:
    cd D:\build\ruby
    C:\src\ruby\win32\configure --prefix=C:/usr/local
    nmake
    nmake test
    nmake install

== Bugs

You can ((*NOT*)) use a path name contains any white space characters as
the ruby source directory, this restriction comes from the behavior of
(({!INCLUDE})) directives of (({NMAKE})).
((- you may call it a bug. -))
