From 2a11665945d510e1a4df8dc44dc3668b01945ade Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Sat, 7 Oct 2006 05:35:32 -0600 Subject: [PATCH] kbuild: distinguish between errors and warnings in modpost Some of modpost's warnings are fatal, and some are not. Adopt the compiler distinction between errors and warnings by calling merror() for fatal diagnostics and warn() for non-fatal ones. merror() was used as replacemtn for error() to avoid clash with glibc Signed-off-by: Matthew Wilcox Signed-off-by: Sam Ravnborg --- scripts/mod/modpost.c | 22 +++++++++++++++++++--- scripts/mod/modpost.h | 1 + 2 files changed, 20 insertions(+), 3 deletions(-) diff --git a/scripts/mod/modpost.c b/scripts/mod/modpost.c index 5f2ecd51bd..b10b69b56a 100644 --- a/scripts/mod/modpost.c +++ b/scripts/mod/modpost.c @@ -55,6 +55,17 @@ void warn(const char *fmt, ...) va_end(arglist); } +void merror(const char *fmt, ...) +{ + va_list arglist; + + fprintf(stderr, "ERROR: "); + + va_start(arglist, fmt); + vfprintf(stderr, fmt, arglist); + va_end(arglist); +} + static int is_vmlinux(const char *modname) { const char *myname; @@ -1307,9 +1318,14 @@ static int add_versions(struct buffer *b, struct module *mod) exp = find_symbol(s->name); if (!exp || exp->module == mod) { if (have_vmlinux && !s->weak) { - warn("\"%s\" [%s.ko] undefined!\n", - s->name, mod->name); - err = warn_unresolved ? 0 : 1; + if (warn_unresolved) { + warn("\"%s\" [%s.ko] undefined!\n", + s->name, mod->name); + } else { + merror("\"%s\" [%s.ko] undefined!\n", + s->name, mod->name); + err = 1; + } } continue; } diff --git a/scripts/mod/modpost.h b/scripts/mod/modpost.h index d398c61e55..0858caa9c0 100644 --- a/scripts/mod/modpost.h +++ b/scripts/mod/modpost.h @@ -145,3 +145,4 @@ void release_file(void *file, unsigned long size); void fatal(const char *fmt, ...); void warn(const char *fmt, ...); +void merror(const char *fmt, ...); -- 2.39.5
