From 5b0f1f7d1375c31280a68b51d5737f4d95df06bf Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Thu, 14 Oct 2004 05:48:59 +0000 Subject: [PATCH] Because libraries on Windows lack useful version information, the zlib guys had to change the name to differentiate with older versions when a backward incompatibility came up. Of course, we need to adapt. This change simply tries to load the library through the newer name (ZLIB1) first, and if that fails, it tries the good old ZLIB. --- crypto/comp/c_zlib.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/crypto/comp/c_zlib.c b/crypto/comp/c_zlib.c index 7553a2d107..64101bd084 100644 --- a/crypto/comp/c_zlib.c +++ b/crypto/comp/c_zlib.c @@ -357,7 +357,17 @@ COMP_METHOD *COMP_zlib(void) if (!zlib_loaded) { #if defined(OPENSSL_SYS_WINDOWS) || defined(OPENSSL_SYS_WIN32) - zlib_dso = DSO_load(NULL, "ZLIB", NULL, 0); + zlib_dso = DSO_load(NULL, "ZLIB1", NULL, 0); + if (!zlib_dso) + { + zlib_dso = DSO_load(NULL, "ZLIB", NULL, 0); + if (zlib_dso) + { + /* Clear the errors from the first failed + DSO_load() */ + ERR_clear_error(); + } + } #else zlib_dso = DSO_load(NULL, "z", NULL, 0); #endif -- 2.25.1
