Enabling --write_hist_log=foo fails if ZLIB not enabled #1996
Description
- [ x] I have read the GitHub issues section of REPORTING-BUGS.
Description of the bug:
Running a local build of fio (no client/server setup), and attempting to use --write_hist_log=, we get a failure due to this check in init.c (l.1771 at HEAD):
#ifndef CONFIG_ZLIB
if (td->client_type) {
log_err("fio: --write_hist_log requires zlib in client/server mode\n");
goto err;
}
#endif
client_type is always non-zero since FIO_CLIENT_TYPE_CLI is 1, _GUI is 2.
Environment: Linux version 6.6.64, x86
fio version: fio-3.36.0
