| Changeset | Fix compilation on RHEL4. These (very old) systems ship with openssl-0.9.7a which defines EVP_MAX_MD_SIZE to 36, a smaller constant than bareos' CRYPTO_DIGEST_MAX_SIZE (64). This mismatch results in the following error on attempt to compile crypto_openssl.c: crypto_openssl.c:58:2: #error "EVP_MAX_MD_SIZE != CRYPTO_DIGEST_MAX_SIZE, please update src/lib/crypto.h" The purpose of the preprocessor sanity check that causes this error is to make sure that various arrays of length CRYPTO_DIGEST_MAX_SIZE are large enough for all message digests. So all we actually need to check for is that EVP_MAX_MD_SIZE is no larger than CRYPTO_DIGEST_MAX_SIZE. Weakening the condition of the above check from "!=" to ">" turned out to be enough to compile bareos on Red Hat Enterprise Linux 4 (using --client-only though). The resulting executable worked with no problems. This patch also adds a comment that explains the purpose of the check. Signed-off-by: Marco van Wieringen <marco.van.wieringen@bareos.com> |
