いろいろ試す63
ああもうこんな季節だ…忙しいのに頭が空回りで何もできていない…
とりあえずできることをできるだけ頑張っていく…!!
●ねむいさんのぶろぐhttps化
タイトルの通りでござます。私のぶろぐの母体"びぃブログ"の仕様が
常時https化したことにより私のぶろぐもhttpsに強制的に変わったの
ですが…
10年来使用してきたソースコードハイライト機能syntax highliterが
今回のhttps化で機能しなくなったのが判明し別のハイライト機能に
切り替えることにしました。それで見つかったのがhighlight.jsです。
かつてのsyntax highliterとほぼ同じ表示感覚で使用でき、表示方法も
ほぼ同じ感覚でした。9月末からhighlight.jsを導入しております。
こんな感じにソースコードの
//ハイライト表示ができます
しかしながらhtmlタグがsyntax highliterのころとは微妙に違うので
過去にさかのぼってブログの記事をせっせと修正しました…
くそ…もっと早くやっておけばよかった…
いちおうすべての記事でhighlight.jsに対応しましたが疲れた…
●OneDriveが仕様変更で古い共有リンク全滅
あ”あ”あ”あ”あ”あ”あ”あ”あ”あ”あ”あ”!!!!
9月末くらいの仕様変更でおきぱにおいてあるSTM32のプロジェクトとか
OpenOCDバイナリとかのリンク全部不通になってたぁああああ!!!
というわけでこちらにも対応して全部共有リンクを再生成してソース
コード置き場のリンクはちゃんとダウンロードできるよう修正いたし
ました…あとは過去のぶろぐ中に張った直リンクたちですが数が膨大に
あるのですがこちらもできる範囲で適宜修正していこうと思います…
また、記事を見直して10年以上前の古いものはリンク仕舞いする個所も
あるのでご注意願います…なるべく残せるようにがむばります…
●最新のarm-gccのgdbの挙動がおかしい?
う〜〜ん私のやり方が悪いのかどっちが悪いのか断定はできませんが
現時点で最新のArm GNU Toolchain Version 13.3.Rel1のgdbなんですが、
なんでか"tbreak main"が効かずデバッグ開始時にmain関数の先頭で
止まってくれません。
*問題の13.3.Rel1(GDB14.2)の場合
ソースコードはスタートアップの最初のところを示していますが
breakがかからずそのままプログラムが走ってしまいます。
↓ログはこんな感じ。Continuing...の後音沙汰がありません。

古いほうは古いほうでちょっと問題があってなんでかバイナリサイズが
256MBもあるデバッグビルドになっており、elfファイルの読み込み時間も
時間がかかります(私の環境ではそこまで気にならなかった)。
切り分けのためにFreddieChopin氏のarm-gcc野良ビルド"Bleeding-Edge"
を使ってみます…(32bit版が動作しなかったので64bit版を使います)
GDBが14.2になったのが原因なら同じ14.2なら再現性があるはずですが…
ちゃんとmain関数の先頭で停止しますね…。

FreddieChopin氏一番新しい版はGDB15.2まであがっておりましたので
こちらでも念のため確認してみます。
こちらもちゃんとmain関数の先頭で停止します。

ううむ…バージョンの違いで起こった現象でもなさそうですしビルド環境の
差なのでしょうか…あとARM公式のはx86版なのが気にかかりますが…
ひとまずはFreddieChopin氏の物を使ってその場をしのぎつつARM公式の
次回リリース版のGDBの挙動を待つとしましょうか…
CodeLiteを使ったデバッグ方法を何とか安定させ正式に公開したいのですが
なかなか手ごわいです…
