the problem has been solved.
the cause is that there is an old libwolfssl.so in dir,/usr/lib.evreytime i make the wolfssl-4.5.0 files, the gcc upgrades libwolfssl.so only in another dir,ie,/usr/local/lib.i deleted libwolfssl.so in /usr/lib,then everything looks good during making my code.

thank you anyway

I added the same code lines into wolfssl-4.5.0\examples\echoclient\echoclient.c

void echoclient_test(void* args)
{
  ......
    ssl = SSL_new(ctx);
    tcp_connect(&sockfd, yasslIP, port, doDTLS, 0, ssl);
#if 1
    {//added test code
    WOLFSSL_BIO *mRbio = wolfSSL_BIO_new(wolfSSL_BIO_s_mem());
    WOLFSSL_BIO *mWbio = wolfSSL_BIO_new(wolfSSL_BIO_s_mem());
    wolfSSL_set_bio(ssl, mRbio, mWbio);
    }
#endif
    SSL_set_fd(ssl, sockfd);
#if defined(USE_WINDOWS_API) && defined(CYASSL_DTLS) && defined(NO_MAIN_DRIVER)
    /* let echoserver bind first, TODO: add Windows signal like pthreads does */
    Sleep(100);
#endif
   ......
}

then wolfssl-4.5.0$ /make clean;make
as a result, no error occur.it's well done.
i'm confused what's the cause of the problem.
i'm expecting an advice.

Hi, dgarske,
I follow your advice to correct my code,but sorry,it dos'nt work.
I made a simple test.
the original ssl-tutorial-2.2 works very well.no problem during compiling and running.
but, if i add some code lines in the tcpcli01.c,the compiler allways reports some errors.

#include    "unp.h"
#include <wolfssl/options.h>
#include    <wolfssl/ssl.h>

int main(int argc, char **argv)
{
....
  if( (ssl = wolfSSL_new(ctx)) == NULL) {
    fprintf(stderr, "wolfSSL_new error.\n");
    exit(EXIT_FAILURE);
  }
   
#if 1
  {//added test code
    WOLFSSL_BIO *mRbio = wolfSSL_BIO_new(wolfSSL_BIO_s_mem());
    WOLFSSL_BIO *mWbio = wolfSSL_BIO_new(wolfSSL_BIO_s_mem());
    wolfSSL_set_bio(ssl, mRbio, mWbio);
  }
#endif

  wolfSSL_set_fd(ssl, sockfd);
  str_cli(stdin, ssl);        /* do it all */
  ...
}

after make,it says:
qn@Hisino-Linux-srv:~/smb/tls/wolfssl/ssl-tutorial-2.2/finished_src/echoclient$ make

Hi, dear friend,
  I'm using wolfssl 4.5.0 to replace openssl.
  I'm using gcc to compile a c file.
  First ,execte ./configure --enable-opensslall --enable-opensslextra
  Then, make
   and, sudo make install
   and, compile my c file.but it says :
wrp.c:(.text+0x10e): undefined reference to `wolfSSL_add_all_algorithms'
wrp.c:(.text+0x113): undefined reference to `wolfSSL_RAND_status'
wrp.c:(.text+0x14d): undefined reference to `wolfSSL_BIO_new_mem_buf'

wrp.c:(.text+0x4ed): undefined reference to `wolfSSL_X509_STORE_set_flags'
It seems all the above functions are in src/ssl.c.
Pls tell me how to add the functions to the libwolfssl.so

  Thks a lot.
