Question

So bauen ich die superbible 6. Auflage bekam, und ich versuche, den Beispielcode Rahmen cmake und machen, aber diese Fehlermeldung erhalten:

Was bin ich? Soweit ich das beurteilen kann, habe ich bereits alle Abhängigkeiten installiert.

Answer 1

Es ist ein Fehler in CMakeLists.txt in Zeile 13. (https://github.com/openglsuperbible/sb6code/blob/master/CMakeLists.txt)

Ändern Sie "elif (UNIX)" zu "elseif (UNIX)", und es wird in Ordnung sein.

Answer 2

als @AndonMColeman vorgeschlagen, Sie -lGL und -ldlam Ende müssen der Bibliotheken Liste. Verwenden Sie dafür das Makro target_link_libraries.

Wenn Sie CMakeLists.txt aus Ihrem Projekt zur Verfügung stellen würde es viel einfacher, Ihnen eine genaue Zeichenfolge vorschlagen/ändern hinzuzufügen;)
