libssh2 1.6版更改编译通过（OpenSSL 1.0.2d)

  转载请注明出处！
最近编译libssh2时，一直不能通过，参照libssh2和openssl源代码，对libssh2做如下修改。

1 在src/openssl.h 文件中增加如下头文件

  #include <openssl/rsa.h>

#include <openssl/dsa.h>

2 在src/openssl.h

src/openssl.h 
Showing the top two matches. Last indexed on Jun 13.
   

    
131
#define libssh2_hmac_sha1_init(ctx, key, keylen) \
132
  HMAC_Init(ctx, key, keylen, EVP_sha1())
133
#define libssh2_hmac_md5_init(ctx, key, keylen) \
134
  HMAC_Init(ctx, key, keylen, EVP_md5())
135
#define libssh2_hmac_ripemd160_init(ctx, key, keylen) \
   

改为如下

src/openssl.h 
Showing the top two matches. Last indexed on Jun 13.
   

    
131
#define libssh2_hmac_sha1_init(ctx, key, keylen) \

  HMAC_Init_ex(ctx, key, keylen, EVP_sha1(),NULL)
133
#define libssh2_hmac_md5_init(ctx, key, keylen) \
134
  HMAC_Init_ex(ctx, key, keylen, EVP_md5(),NULL)
135
#define libssh2_hmac_ripemd160_init(ctx, key, keylen) \

140
#define libssh2_hmac_cleanup(ctx) HMAC_cleanup(ctx)
141

142
#define libssh2_crypto_init() OpenSSL_add_all_algorithms()
   

改为

src/openssl.h 
Showing the top match. Last indexed on Jun 13.
   

    
139
#define libssh2_hmac_final(ctx, data) HMAC_Final(&(ctx), data, NULL)
140
#define libssh2_hmac_cleanup(ctx) HMAC_CTX_cleanup(ctx)
141

142
#define libssh2_crypto_init() OpenSSL_add_all_algorithms()
   

原因：

      可以查看openssl源码 hmac.h文件中（如下）：这2个函数是有条件编译的 USE_DEPRECATED,  但是查看openssl的change log , 最新的openssl 默认是NO DEPRECATED, 故在编译libssh2时会报 NO DEFINE REFRENCE .

Changes between 1.0.2 and 1.1.0

   *) config has been changed so that by default OPENSSL_NO_DEPRECATED is used.

     Access to deprecated functions can be re-enabled by running config with
     "enable-deprecated". In addition applications wishing to use deprecated
     functions must define OPENSSL_USE_DEPRECATED. Note that this new behaviour
     will, by default, disable some transitive includes that previously existed
     in the header files (e.g. ec.h will no longer, by default, include bn.h)
     [Matt Caswell]

   
void HMAC_CTX_init(HMAC_CTX *ctx);

void HMAC_CTX_cleanup(HMAC_CTX *ctx);



#ifdef OPENSSL_USE_DEPRECATED

/* deprecated */

# define HMAC_cleanup(ctx) HMAC_CTX_cleanup(ctx)



/* deprecated */

DECLARE_DEPRECATED(__owur int HMAC_Init(HMAC_CTX *ctx, const void *key, int len,

                     const EVP_MD *md));



#endif

/*__owur*/ int HMAC_Init_ex(HMAC_CTX *ctx, const void *key, int len,

                            const EVP_MD *md, ENGINE *impl);

/*__owur*/ int HMAC_Update(HMAC_CTX *ctx, const unsigned char *data,

                           size_t len);

/*__owur*/ int HMAC_Final(HMAC_CTX *ctx, unsigned char *md,

最后libssh2编译成功。
