Tipp: make-Ausgaben abkürzen (stderr->stdout), Grep/RegEx
Verfasst: So Jun 09, 2013 3:01 pm
Ich bin derzeit mal wieder damit beschäftigt, mich mit clang auseinander zu setzen. Um ein Verzeichnis zu kompilieren erhalte ich noch einiges an Fehlermeldungen:
Viel Text, dabei interessiert mich eigentlich nur sehr wenig davon - nämlich die Zeilen in denen ein Warning oder ein Error vorkommt. Das meiste lässt sich damit nämlich bereits lösen.
Außerdem interessiert mich der Fortschritt, den mein MakeFile ausgibt in dem Moment auch nicht wirklich.
Leider kann man nach Warning oder Error nicht so einfach grepen. Eine entsprechende Expression muss her. Die sieht in dem Fall so aus:
Ich suche nach einem String, der einen Doppelpunkt, gefolgt von Ziffern(Zeilennummer), Doppelpunkt, Spaltennummer (Ziffern), Doppelpunkt und nach einem Leerzeichen entweder das Wort "error" oder "warning" enthält.
Soweit so gut. Nun gibt clang die Fehler aber nicht an die Standard-Konsole (1) aus, die ich per Pipe greppen könnte, sondern an die Fehlerkonsole (2). Wir müssen also noch die Fehlerkonsole in die Standardkonsole umlenken. Das geht mit "2>&1".
Und so kommen wir zu einem kompletten Befehl:
der eine übersichtliche Ausgabe erzeugt, die man schnell abarbeiten kann.
