# 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`.
