Hi,
I believe that zpipe.c used to be working.
But it is still working now?
I get it compiled OK,
gcc -g -lz -o zpipe zpipe.c
but wasn't able to run it:
$ ./zpipe
bash: ./zpipe: Permission denied
I get the same result even I put an output immediately after main:
/* compress or decompress from stdin to stdout */
int main(int argc, char **argv)
{
fputs("zpipe 1\n", stderr);
Anyone has any idea how to fix it?
Thanks
PS. Enclosed is the strace log:
$ strace ./zpipe
execve("./zpipe", ["./zpipe"], [/* 130 vars */]) = -1 EACCES (Permission
denied)
dup(2) = 3
fcntl(3, F_GETFL) = 0x8002 (flags O_RDWR|
O_LARGEFILE)
fstat(3, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 2), ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0)

exit_group(1) = ?
