How do I get a list of installed files from a package?
$ dpkg-query -L fontconfig /. /usr /usr/bin /usr/bin/fc-query /usr/bin/fc-cache /usr/bin/fc-cat [...]
$ apt-file search fontconfig.pc libfontconfig1-dev: usr/lib/pkgconfig/fontconfig.pc libfontconfig1-dev: usr/lib/pkgconfig/fontconfig.pc
Schon viele male habe ich beim Linken solch eine Fehlermeldung bekommen:
main.c:(.text+0x4b908): undefined reference to `clock_gettime'
Lösung kann sein, dass alle Object-Dateien VOR den Libraries sein müssen:

1. Die anzuheftende Batchdatei von batch.bat nach batch.exe umbenennen.
2. Die Batchdatei nun in die Taskleiste ziehen und anheften.
3. Nun die original Batchdatei wieder umbenennen in batch.bat.
4. Mit gedrückter Shift-Taste mit der rechten Mausstaste auf die Verknüpfung klicken und auf Eigenschaften klicken.
5. Unter Ziel nun den korrekten Pfad zur Batchdatei eingeben. Es reicht aus, aus dem .exe ein .bat zu machen.

Zuerst nur PS-Treiber installieren.
Danach neuer Drucker installieren mit Pfad zu Treiber.
Schlussendlich über Reiter “Anschlüsse” auf “NtwPort00” (RAW) wechseln.
Besser:
Geräte und Drucker -> Drucker hinzufügen -> Ein lokaler Drucker hinzufügen -> Neuer Anschluss erstellen -> Standart TCP/IP Port -> IP-Adresse -> Treiber angeben. Fertig!
