[mvapich-discuss] Re: [mvapich] Announcing the Release of MVAPICH2 1.4RC1

Dear Sir,

Regarding to our previous  mailing conversation about compilation error 
with --enable-g=all.

 mvapich2-1.2-2009-05-12 was supposed to be fixed that bug but  still i  
encountered following error while compiling for udapl device with above 
flag.

/home/htdg/pn_mpi/mvapich2-1.2-2009-05-12/lib/libmpich.a(ch3u_handle_connection.o)(.text+0x8e): 
In function `MPIDI_CH3U_Handle_connection':
/home/htdg/pn_mpi/mvapich2-1.2-2009-05-12/src/mpid/ch3/src/ch3u_handle_connection.c:63: 
undefined reference to `MPIDI_CH3_VC_GetStateString'

due to "MPIDI_CH3_VC_GetStateString" this function call which is not 
defined any where

then findout that its defination should be in following file.

"mrail/src/udapl/udapl_channel_manager.c"

#ifdef USE_DBG_LOGGING
const char *MPIDI_CH3_VC_GetStateString(MPIDI_VC_t *vc)
{
    return NULL;
}
#endif

This definition may not be correct but that error was suppressed.

Hope the appropriate definition is being added in released RC version.

with Best Regards,
Nilesh Awate
