Hi Akash,
Thansks, now after devtoolset,
@Benoit Ganne (bganne) <bga...@cisco.com> , @Ole Troan
<otr...@employees.org>
i am getting following error
[root@8f57181df3a1 vpp_c_api_examples]# gcc vpp_api_client_test3.c -o
vpp_api_client_test3.o -lvlibmemoryclient -lsvm -lvppinfra -lvlib

collect2: error: ld returned 1 exit status
[root@8f57181df3a1 vpp_c_api_examples]#
Let me paste the code again,
#include<stdio.h>
#include<stdlib.h>
#include <vlibapi/api.h>
#include <vlibmemory/api.h>
#include <vpp/api/vpe_msg_enum.h>
#define vl_typedefs
#define vl_endianfun
#include <vpp/api/vpe_all_api_h.h>
#undef vl_typedefs
#undef vl_endianfun
int main()
{
char *name = "vpp-test-app";
clib_mem_init_thread_safe (0, 64ULL << 20);
if (vl_client_api_map("/vpe-api"))
{
printf("unable to map....\n");
goto quit;
}
if (vl_client_connect("vpp-test-app", 0, 32) < 0)
{
printf("unable to connect \n");
vl_client_api_unmap();
goto quit;
}
printf("successfully connected... \n");
quit:
return 0;
}
Is this wrong way, i am trying to use APIs ?
Thanks,
Regards
Venu
