I see in the vpp/src/configure , that is generated by the vpp/src/congiure.ac ,
the following code :
#ifdef __cplusplus
extern "C"
#endif
char ibv_fork_init ();
int
main ()
{
return ibv_fork_init ();
;
return 0;
}
_ACEOF
if ac_fn_c_try_link "$LINENO"; then :
ac_cv_lib_ibverbs_ibv_fork_init=yes
else
ac_cv_lib_ibverbs_ibv_fork_init=no
fi
this code effects on the issue in run time :
ubuntu@ubuntu:~/vpp.shacharbe$<mailto:ubuntu@ubuntu:~/vpp.shacharbe$> vpp -c

Hi ,
I see in the vpp/src/configure.ac the following code :
AM_COND_IF([WITH_DPDK_MLX5_PMD],
[
AC_CHECK_LIB([ibverbs], [ibv_fork_init],
[with_ibverbs_lib=yes],
[AC_MSG_ERROR([ibverbs library not found])])
])
Can you explain what was the motivation to override the ibv_fork_init
prototype ?
Hi Shachar,
Why do you mean by override the ibv_fork_init prototype?
Thanks,
Damjan
