Tcl/Tk8.5b1

Tcl/Tk 8.5 の最初のβ版が9月２６日付けでリリースされました。β版では新機能の追加がないはずですので、あまり長い時間をかけずに正式版 8.5.0 がリリースされることを望むばかりです。デバグを精力的にしなければ…。

今週末に、Linux 上の MinGW Cross Compiler でコンパイル、インストーラを作成して、ビットウォーク版 Tcl/Tk 8.5 for Windows をリリースする予定です。なお、今回から MinGW Cross Compiler で生成した Tcl/Tk のバイナリは、MinGW Cross Compiler のプロジェクトサイトで、

[PRODUCT] Tcl/Tk

というパッケージ名で公開します。もちろん、Inno Setup でパッケージを生成したインストーラとして公開します。

全てがクロスコンパイル環境でコンパイル可能かどうか、まだ確認していませんが、現時点で収録予定の拡張パッケージは次の通りです。

- Tcl/Tk 8.5b1
- Thread
- TkCon
- TclX
- Incr Tcl/Tk
- Incr Widgets
- Tcllib
- BWidget
- Tktable
- Tile
- TbcLoad
- TclCompiler
- ICONS

何か他に同梱をご希望の拡張パッケージがあればコメントを下さい。
ただし、tkImg と BLT はもともと同梱したいパッケージなのですが、ビルドの成功に至っていません。また、snack のビルドは DirectX の開発環境が一部必要になるので、今のところクロスコンパイル環境では対応しません。Linux 上でのクロスコンパイルとは別件になりますが、このパッケージだけ Cygwin 環境でビルドできないかどうか試してみようかとも思っています。
