A better solution might be to move sched_setaffinity() test from auto/os/linux to auto/unix instead. Patch below (untested). # HG changeset patch # User Maxim Dounin <mdou...@mdounin.ru> # Date 1495814031 -10800 # Fri May 26 18:53:51 2017 +0300 # Node ID d4d316c4503f7b9bbf47b0006822e4438e6e641a # Parent 9552758a786e20c70130427298895bc782a754c5 Configure: sched_setaffinity() test moved to auto/unix. The sched_setaffinity() function was introduced in DragonFly BSD 4.7, so it is no longer Linux-specific. diff --git a/auto/os/linux b/auto/os/linux --- a/auto/os/linux +++ b/auto/os/linux @@ -157,20 +157,6 @@ ngx_feature_test="if (prctl(PR_SET_DUMPA . auto/feature -# sched_setaffinity() - -ngx_feature="sched_setaffinity()" -ngx_feature_name="NGX_HAVE_SCHED_SETAFFINITY" -ngx_feature_run=no -ngx_feature_incs="#include <sched.h>" -ngx_feature_path= -ngx_feature_libs= -ngx_feature_test="cpu_set_t mask; - CPU_ZERO(&mask); - sched_setaffinity(0, sizeof(cpu_set_t), &mask)" -. auto/feature - - # crypt_r() ngx_feature="crypt_r()" diff --git a/auto/unix b/auto/unix --- a/auto/unix +++ b/auto/unix @@ -300,6 +300,18 @@ if [ $ngx_found = no ]; then fi +ngx_feature="sched_setaffinity()" +ngx_feature_name="NGX_HAVE_SCHED_SETAFFINITY" +ngx_feature_run=no +ngx_feature_incs="#include <sched.h>" +ngx_feature_path= +ngx_feature_libs= +ngx_feature_test="cpu_set_t mask; + CPU_ZERO(&mask); + sched_setaffinity(0, sizeof(cpu_set_t), &mask)" +. auto/feature + + ngx_feature="SO_SETFIB" ngx_feature_name="NGX_HAVE_SETFIB" ngx_feature_run=no -- Maxim Dounin http://nginx.org/ _______________________________________________ nginx-devel mailing list nginx-devel@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx-devel
