macOS Load sha256 and EVP_sha256 from system default openssl header and lib fail

[marsyanggo]

Hi Dear all

I meet a openssl problem again.

I am almost done the porting work form windows to Mac.

The environment setting is as below.

I had added /Developer/SDKs/MacOSX10.5.sdk/usr/include/ in the search

header path.

Add -lssl -lcrypto in link other flag and add the libcrypto.dylib and

libssl.dylib.


The most functions I use in openssl are work, but the two function

sha256() and EVP_sha256().

I found the some compile flag in the evp.h header.

#ifdef OPENSSL_FIPS
#ifndef OPENSSL_NO_SHA256
const EVP_MD *EVP_sha224(void);
const EVP_MD *EVP_sha256(void);
#endif
#ifndef OPENSSL_NO_SHA512
const EVP_MD *EVP_sha384(void);
const EVP_MD *EVP_sha512(void);
#endif
#endif

Are there any other setting I should do before I call the two function.

Thanks for your help.
