+# Datatypsimplementationer för kursen datastrukturer och algoritmer vid Institutionen för datavetenskap, Umeå universitet.
+
+# Version 2.2.2.2, 2025-01-24.
+
+# Givna datatyper
+
+Här återfinns implementationer av några av de datatyper som kommer användas
+under denna kurs. Nedan följer information om hur dessa kompileras och hur
+`minimal working examples` körs för varje datatyp.
+
+## Headerfiler
+
+Headerfilerna för de givna datatyperna är alla samlade i mappen `include`. Dessa
+kan inkluderas med hjälp av `-I`-flaggan till `gcc`, se exempel nedan.
+
+## undefined reference
+
+Det är möjligt att du får t.ex. följande felmeddelande:
+
+```bash
+/tmp/ccLd0e5H.o: In function `queue_empty':
+queue.c:(.text+0x14): undefined reference to `list_empty'
+```
+
+Detta innebär att du inte anget alla nödvändiga C-filer till kompilatorn. I
+fallet ovan saknas `list.c`.
