[b]Hi,
i'm using opensolaris 2008.05 updated to b96 and writing a little C program
(with setuid) to exec a java jar.
Here the code:[/b]
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/wait.h>
int main() {
pid_t pid;
int status;
if ((pid = fork()) < 0) {
printf("Fork error\n");
exit(0);
} else if (pid == 0) { //child
execl ("/usr/java/bin/java","java", "-jar", "DD.jar", NULL);
exit(0);
} else { //father
waitpid(pid,&status,0);
}
}
[b]then i do:[/b]
gcc runner.c -o runner
pfexec chown root:root runner
pfexec chmod u+s runner
[b]when execute runner, this error will be returned:[/b]
ld.so.1: java: fatal: libjli.so: open failed: No such file or directory
[b]
here the truss output:[/b]
