From 8b0fbcc6568308794ef198f8e96093b00ba90ca4 Mon Sep 17 00:00:00 2001 From: Guillaume Melquiond Date: Fri, 8 Jan 2016 10:46:26 +0100 Subject: Be more verbose about failure to compile libraries to native code. On a machine with only 1GB of memory (e.g. in a VM), the compiler might be abruptly killed by a segfault. We were not getting any feedback in that case, making it harder to debug. --- kernel/nativelib.ml | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'kernel/nativelib.ml') diff --git a/kernel/nativelib.ml b/kernel/nativelib.ml index b2142b43c..81470f901 100644 --- a/kernel/nativelib.ml +++ b/kernel/nativelib.ml @@ -77,7 +77,17 @@ let call_compiler ml_filename = ::include_dirs @ ["-impl"; ml_filename] in if !Flags.debug then Pp.msg_debug (Pp.str (compiler_name ^ " " ^ (String.concat " " args))); - try CUnix.sys_command compiler_name args = Unix.WEXITED 0, link_filename + try + let res = CUnix.sys_command compiler_name args in + let res = match res with + | Unix.WEXITED 0 -> true + | Unix.WEXITED n -> + Pp.(msg_warning (str "command exited with status " ++ int n)); false + | Unix.WSIGNALED n -> + Pp.(msg_warning (str "command killed by signal " ++ int n)); false + | Unix.WSTOPPED n -> + Pp.(msg_warning (str "command stopped by signal " ++ int n)); false in + res, link_filename with Unix.Unix_error (e,_,_) -> Pp.(msg_warning (str (Unix.error_message e))); false, link_filename -- cgit v1.2.3
