Okay...I think I'm either an idiot or going slowly insane. I'll admit
I'm not the most savvy C programmer but the following code gives me an
error:
## Source File##
#include <stdio.h>
#include <readline/readline.h>
#include <readline/history.h>
int main() {
char *line;
line = readline("Test: ");
return 0;
}
##Source File##
##Error##
/var/tmp//ccqxIZxQ.o(.text+0x25): In function `main':
: undefined reference to `readline'
##Error##
What sucks is that readline() seems like it would be the perfect
solution. I'm not doing anything special but my I don't want to start
getting into bad habits like using gets().
