[ruby-list:49519] OSX ruby-tkのextconf.rb

天野といいます。

環境は、OSX 10.8.4、XCode 4.6.3 ActiveTcl8.5.14
OSデフォルトとして、tcltk8.5.9がインストールされています。

最近こちらで、OSX10.8で、ruby-tkがインストールできない、できても落ちるという話が出ました。brewやmac portsなどを利用しての話のようでしたが、当方は、ソースからのインストールでうまくいきませんでした。

ruby-2.0.0-p247および1.9.3-p448では、

./configure --enable-shared --enable-pthread
make
で、

check struct members..
check libraries....
Use ActiveTcl libraries (if available).
Search tclConfig.sh and tkConfig.sh.wrong number of arguments (2 for 1)
Failed to configure tk. It will not be installed.
configuring tk/tkutil
Failed to configure tk/tkutil. It will not be installed.
となります。

以前はこうなりませんでした。
ずいぶん前のソースになりますが、たとえば1.9.2-p320だと、
make
make install
問題なく終わり、ruby-tkも動きます。

tk/extconf.rbを比べると
308行目から

1.9.2が

  paths = [
    #"~/Library/Frameworks",
    "/Library/Frameworks",
    "/Network/Library/Frameworks", "/System/Library/Frameworks"
  ]
  paths.reverse! unless TkLib_Config["ActiveTcl"] # system has higher priority

  paths.map{|dir| dir.strip.chomp('/')}.each{|dir|
    next unless File.directory?(tcldir = File.join(dir, "Tcl.framework"))
    next unless File.directory?(tkdir  = File.join(dir, "Tk.framework"))
    TkLib_Config["tcltk-framework"] = dir
    return [tcldir, tkdir]
  }

1.9.3-p448が

  paths = [
    #"~/Library/Frameworks",
    "/Library/Frameworks",
    "/Network/Library/Frameworks", "/System/Library/Frameworks"
  ]
  paths.reverse! unless TkLib_Config["ActiveTcl"] # system has higher priority

  paths.map{|dir| dir.strip.chomp('/')}.each{|dir|
    next unless File.exist?(File.join(dir, "Tcl.framework", "Headers"))
    next unless File.directory?(tcldir = File.join(dir, "Tcl.framework"))
    next unless File.exist?(File.join(dir, "Tk.framework"), "Headers")
    next unless File.directory?(tkdir  = File.join(dir, "Tk.framework"))
    TkLib_Config["tcltk-framework"] = dir
    return [tcldir, tkdir]
  }


next unless File.exist?(File.join(dir, "Tcl.framework", "Headers"))
next unless File.exist?(File.join(dir, "Tk.framework"), "Headers")
を削除すると
makeは通りますが、
インストール後、
require "tk"で落ちます（ruby-2.0.0-p247および1.9.3-p448どちらも同じ）。

This probably means that tk wasn't installed properly.

extconf.rbをruby-1.9.2-p320のものと取り替えると、makeは問題なく、
インストール後のruby-tkの動作も問題ないようです。（ActiveTcl8.5.14の方とくっついて、demo-jp/widgetも普通に動いています。ruby-2.0.0-p247および1.9.3-p448どちらも動作しています。）
