Hi,
I have a question regarding this warning message (which is repeated many
times):
In file included from src/os/unix/ngx_posix_config.h:74,
from src/core/ngx_config.h:37,
from src/core/nginx.c:7:
/usr/include/malloc.h:4:2: warning: #warning “<malloc.h> is obsolete,
use <stdlib.h>”
stdlib.h seems to be assumed always, and malloc.h hasn’t been needed for
some time. Do some of the supported systems still use malloc.h instead
of stdlib.h for this stuff? Or can the malloc.h detection simply be
removed from auto/headers, ngx_posix_config.h, et al?

What OS ?
malloc.h is required for memalign(), however, now memalign() is not used
in
nginx.

This is on OpenBSD. I maintain the OpenBSD nginx port, and I am looking
for ways to reduce warnings and generally improve platform support.
FYI, it’s working well as far as I’ve tested except for mail, which I
have not set up an auth server to test yet.

OpenBSD’s malloc.h has:
#warning “<malloc.h> is obsolete, use <stdlib.h>”
#include <stdlib.h>
So autoconf lets it be used.
One way is to add
./configure … --with-cc-opt="-DNGX_HAVE_MALLOC_H=0"
Yes. I’ll use that unless some better idea comes to me. Thanks!
Note that this is not causing problems. I just like to reduce warnings
so that I can more easily spot real issues, if any should come up.
Thanks again.
