Where did you try to build? Usually, long and size_t (a "common default" for AO_t) have the same underlying type, unless you build with something like MSVC. So far I only get signedness warnings with -Wpointer-sign on both Clang and GCC 14 prerelease, and it is disabled by default on GCC. The patch addresses them. This warning option is documented to enable warnings other than -Wincompatible-pointer-types. It might have been changed in the released version though. > Fix the error by using the correct pointer types. > > Signed-off-by: Edgar Bonet <bo...@grenoble.cnrs.fr> > > diff -r 89093b003fcb -r c2c3b0d74b1a auto/lib/libatomic/conf > --- a/auto/lib/libatomic/conf Fri May 03 20:26:05 2024 +0400 > +++ b/auto/lib/libatomic/conf Thu May 16 11:15:10 2024 +0200 > @@ -19,7 +19,7 @@ > #include <atomic_ops.h>" > ngx_feature_path= > ngx_feature_libs="-latomic_ops" > - ngx_feature_test="long n = 0; > + ngx_feature_test="AO_t n = 0; > if (!AO_compare_and_swap(&n, 0, 1)) > return 1; > if (AO_fetch_and_add(&n, 1) != 1) > _______________________________________________ > nginx-devel mailing list > nginx-devel@nginx.org > https://mailman.nginx.org/mailman/listinfo/nginx-devel -- Sergey Kandaurov _______________________________________________ nginx-devel mailing list nginx-devel@nginx.org https://mailman.nginx.org/mailman/listinfo/nginx-devel
