Greetings,

I'm looking for guidance on how to update the folly and proxygen framework to link to different version of the openssl libraries.  I believe the modifications would need to be made to these files:

- /proxygen-0.32.0/proxygen/folly/folly/configure

- /proxygen-0.32.0/proxygen/configure

Within these configuration files, the logic to check for libssl is as follows:

#ifdef __cplusplus

extern "C"

#endif

char SSL_ctrl ();

int

main ()

{

return SSL_ctrl ();

  ;

  return 0;

}

_ACEOF

if ac_fn_cxx_try_link "$LINENO"; then :

  ac_cv_lib_ssl_SSL_ctrl=yes

else

  ac_cv_lib_ssl_SSL_ctrl=no

fi

rm -f core conftest.err conftest.$ac_objext \

    conftest$ac_exeext conftest.$ac_ext

LIBS=$ac_check_lib_save_LIBS

fi

{ $as_echo "$as_me:${as_lineno-$LINENO}: result: $ac_cv_lib_ssl_SSL_ctrl" >&5

$as_echo "$ac_cv_lib_ssl_SSL_ctrl" >&6; }

if test "x$ac_cv_lib_ssl_SSL_ctrl" = xyes; then :

  cat >>confdefs.h <<_ACEOF

#define HAVE_LIBSSL 1

_ACEOF

  LIBS="-lssl $LIBS"

else

  as_fn_error $? "\"Error: libssl required\"" "$LINENO" 5

fi

 

I attempted to replace the following line with explicit path to version of lssl. 

       LIBS="-lssl $LIBS"

       LIBS="/usr/local/ssl/lib/libssl.a  $LIBS"

The following error is returned. 

             "Error: libssl required\"" "$LINENO" 5

This error indicates that that this check fails:

        if test "x$ac_cv_lib_ssl_SSL_ctrl" = xyes; then :

Any help or pointers is much appreciated.

Thanks,

Joel
