On Linux, signal.h is not required to have access to the signal constants. On FreeBSD, this is not the case and requires signal.h to be explicitly included. This patch adds an include for signal.h in any source file that uses it. Signed-off-by: Mark Weiman <mark.weiman@markzz.com> --- This is a modified patch that just adds signal.h to required files instead of adding a check within meson. lib/libalpm/util.c | 1 + src/pacman/conf.c | 1 + 2 files changed, 2 insertions(+) diff --git a/lib/libalpm/util.c b/lib/libalpm/util.c index b386fde6..46c1d0a1 100644 --- a/lib/libalpm/util.c +++ b/lib/libalpm/util.c @@ -33,6 +33,7 @@ #include <sys/socket.h> #include <fnmatch.h> #include <poll.h> +#include <signal.h> /* libarchive */ #include <archive.h> diff --git a/src/pacman/conf.c b/src/pacman/conf.c index a4f2ba35..cde96716 100644 --- a/src/pacman/conf.c +++ b/src/pacman/conf.c @@ -31,6 +31,7 @@ #include <sys/utsname.h> /* uname */ #include <sys/wait.h> #include <unistd.h> +#include <signal.h> /* pacman */ #include "conf.h" -- 2.31.1
