Error building nginx 1.5.3 on Cygwin

Server NGINX

Hello,

I’m trying to build nginx 1.5.3 on Cygwin using Windows 7. I see the
following output during “make”:

cc -c -pipe -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror

I would appreciate any help to fix this. Thank you!

Looks like socklen_t is signed in your environment, which results
in a warning. Try the following patch:

— a/src/core/ngx_inet.c
+++ b/src/core/ngx_inet.c
@@ -233,7 +233,7 @@ ngx_sock_ntop(struct sockaddr *sa,

     /* on Linux sockaddr might not include sun_path at all */

  •    if (socklen <= offsetof(struct sockaddr_un, sun_path)) {

  •    if (socklen <= (socklen_t) offsetof(struct sockaddr_un,

sun_path)) {
p = ngx_snprintf(text, len, “unix:%Z”);

     } else {

Alternatively, you may just ignore the warning, it’s harmless.

Hi Maxim,

Thanks so much. Your patch worked great.

The build was failing without that change.

Is there any way that patch can be incorporated into the main source, so
that it doesn’t happen again in 1.5.4?

Sure, committed. Thanks for testing.
