Здравствуйте

Начал тут ДЗ делать, и вдруг вот что вылезло:

[root@earth /]# gcc -otest2 ./test2.c
/tmp/cc4yA1Yt.o: In function `main':
/tmp/cc4yA1Yt.o(.text+0x14): undefined reference to `sin'
collect2: ld returned 1 exit status

[root@earth /]# cat test2.c
#include<stdio.h>
#include<math.h>

int main(void)
{
        printf("\n%f\n",sin(2));
        return 0;
}

Это за глюки? и как бы можно это исправить...
Спасибо...

[aen@pi aen]$ gcc -lm -otest ./test.c
[aen@pi aen]$ ./test

Библиотека libm теперь отдельно.

Все правильно, вы не включили libm.so:
gcc -otest2 ./test2.c -lm

Сейчас уже не хочется настраивать нового пользователя (хотя зайти получилось.... нашел в чем причина была)
Лучше подожду пока 7.2RE выйдет, тогда просто все по новой поставлю, и там уже буду нормально работать...
