From 62d6112a7981ad7c34f3b43cffdf00d4662a4f25 Mon Sep 17 00:00:00 2001 From: Mark Adler Date: Sun, 12 Aug 2012 18:08:52 -0700 Subject: Clean up the usage of z_const and respect const usage within zlib. This patch allows zlib to compile cleanly with the -Wcast-qual gcc warning enabled, but only if ZLIB_CONST is defined, which adds const to next_in and msg in z_stream and in the in_func prototype. A --const option is added to ./configure which adds -DZLIB_CONST to the compile flags, and adds -Wcast-qual to the compile flags when ZLIBGCCWARN is set in the environment. --- zutil.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'zutil.c') diff --git a/zutil.c b/zutil.c index 65e0d3b..23d2ebe 100644 --- a/zutil.c +++ b/zutil.c @@ -14,7 +14,7 @@ struct internal_state {int dummy;}; /* for buggy compilers */ #endif -const char * const z_errmsg[10] = { +z_const char * const z_errmsg[10] = { "need dictionary", /* Z_NEED_DICT 2 */ "stream end", /* Z_STREAM_END 1 */ "", /* Z_OK 0 */ -- cgit v1.2.3-55-g6feb
