Affects the current development version since commit 97e52816: When compiling any configuration with CONFIG_NTPD and without CONFIG_FEATURE_NTPD_SERVER, the compiler issues an error: CC networking/ntpd.o networking/ntpd.c: In function ntpd_main: networking/ntpd.c:2128:44: error: struct globals has no member named listen_fd The problem is member listen_fd of struct globals, which is only defined if CONFIG_FEATURE_NTPD_SERVER is selected, but it is referenced in all configurations in line 2128. Instead of an if, there probably should be an #if, but the code is to complicated for me to suggest a proper patch.
Should be fixed in current git. Please report if it is not.
