Hi,
sorry for the cross-posting, but I think it started recently
(therefore current-users, but I don't have an old version to verify)
and the problem is in a pkg (-> tech-pkg):
I'm not even using pthread stuff in this demo, just linking with the
pthread lib:
Program:
-------------
#include <sys/fcntl.h>
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
#include <unistd.h>
#include <string.h>
int main(int argc, char **argv)
{
int ha;
ha = open("/dev/usb0", O_RDONLY);
if (ha == -1) {
fprintf(stderr, "error: %s\n", strerror(errno));
exit(1);
}
printf("success\n");
close(ha);
return(0);
}
-------------
How I compile:
cc -I /usr/pkg/pthreads/include -g pthreads.c -o pt -L/usr/pkg/pthreads/lib -Wl,-R,/usr/pkg/pthreads/lib -lpthread
(N.B. I get a warning when doing this:
/usr/pkg/pthreads/lib/libpthread.so: warning: reference to compatibility sys_errlist[]; include <errno.h> for correct reference
/usr/pkg/pthreads/lib/libpthread.so: warning: reference to compatibility sys_nerr; include <errno.h> for correct reference
)
The resulting program segfaults when doing the open:
gibbon:~/tmp$ ./pt
Segmentation fault (core dumped)
This happens on both i386 and macppc. On alpha it seems to work,
but my real progam shows later funny behaviour.
Should I do a send-pr?
regards,
chris
