Subject: [PATCH] checkpolicy: include <ctype.h> for isprint(3)
|
|||
|
|
MIME-Version: 1.0
|

|
Include the necessary header for isprint(3) to avoid an implicit
|
|||
|
|
function declaration:
|
|||
|
|
|
|||
|
|
policy_scan.l: In function ‘yyerror’:
|
|||
|
|
policy_scan.l:342:13: warning: implicit declaration of function ‘isprint’ [-Wimplicit-function-declaration]
|
|||
|
|
342 | if (isprint((unsigned char)yytext[0])) {
|
|||
|
|
| ^~~~~~~
|
|||
|
|
policy_scan.l:36:1: note: include ‘<ctype.h>’ or provide a declaration of ‘isprint’
|
|||
|
|
35 | #include "y.tab.h"
|
|||
|
|
+++ |+#include <ctype.h>
|
|||
|
|
36 | #endif
|
|||
|
|
|
|||
|
|
This does not currently break the build cause -Werror is stripped for
|
|||
|
|
the parsing code to avoid breakage on old flex/bison versions that might
|
|||
|
|
not generate warning free code.
|
|||
|
|
|
|||
|
|
Fixes: 39b3cc51350a ("checkpolicy: handle unprintable token")
