Behebung von C-Fehler 'unknown type name intptr_t'
English
Deutsch
Problem:
Du hast C-Code wie
example.c
int v = 123;
intptr_t vptr = (intptr_t)&v;aber wenn du versuchst, es zu kompilieren, siehst du eine Fehlermeldung wie
compile_error.txt
main.c: In function ‘main’:
main.c:5:1: error: unknown type name ‘intptr_t’; did you mean ‘__int128_t’?
intptr_t vptr = (intptr_t)&v;
^~~~~~~~
__int128_t
main.c:5:18: error: ‘intptr_t’ undeclared (first use in this function)
intptr_t vptr = (intptr_t)&v;
^~~~~~~~
main.c:5:18: note: each undeclared identifier is reported only once for each function it appears inLösung
Add
fix.c
#include <stdint.h>am Anfang der Quelldatei, wo der Fehler aufgetreten ist.
