!! Description

３／６以降、SADをInte iMacでコンパイルして、FileDialogを呼ぶと以下のメッセージがでます。どうすればよいでしょうか？
（amsad8では、でないんですけどね。）

fork()したプロセスでは、CoreFoundationのこの機能を安全には使えないから、exec()しろということで、メッセージ通りの意味だと思いますが？
おそらく、MacOSX固有の CoreFoundationが出しているメッセージなので、コンパイル時に CoreFoundationがリンクされてるのでは無いでしょうか？

明らかに環境依存問題なので、コンパイル＆実行環境に関する情報が提示されないと検証不能と思われます。
私は、MacOSXの開発環境を維持していないので、だれか検証お願いします。
!!!Akio Morita (2008-03-14 (金) 19:25:06)
吉本氏より、MacOSX 10.5 + Tcl/Tk 8.5の組み合わせで
Core Foundationが Tcl/Tk経由でリンクされているとの
仮説が提示され、検証法として、Tcl/Tkの configure optionの設定
TCLTK_CONFIG_ARG+=--disable-corefoundation
が立案された。
!!!Akio Morita (2008-03-14 (金) 19:30:56)
大西氏より、障害が発生した環境で、
TCLTK_VERSION=8.5.0
TCLTK_CONFIG_ARG+=--disable-corefoundation
のコンパイル条件で追試を行い障害が解消したとの報告有り。
!!!Akio Morita (2008-03-14 (金) 19:34:17)
config/Darwin.specもしくは mk/sad.tcltk.mkへの取り込みに
向けて、disable-corefoundationオプション追加に伴う
既存の環境への副作用の検証待ち(MacOSX 10.4.xと Tcl/Tk 8.4.x)
!!!Akio Morita (2008-03-17 (月) 22:31:24)
Revision 1473で修正を commit

CVS MAIN trunkへのバックポートは、以下のとおり
mk/sad.tcltk.mk    1.14
