Re: [ibr-dtn] terminate called after throwing an instance of 'ibrcommon::socket_exception'

Hi,

What platform/OS are you trying to compile for? I just checked your sample Code on Ubuntu 11.0 and OS X 10.8 just now, and it behaves as expected (ret=0), however recently we found that getaddrinfo can be tricky on different platforms, so if you can give more details about your target platform that might help (e.g. glibc or uclibc?) .

To simplicity, I made the following test program about this situation. I found that getaddrinfo() return -2 ( EAI_NONAME ) when I set AF_INET6 as hints.ai_family. This is strange.

#include <stdio.h>

#include <sys/types.h> #include <sys/socket.h> #include <netdb.h>

int main(int argc, char *argv[]) { struct addrinfo hints, *res; memset(&hints, 0, sizeof hints);

   hints.ai_family = AF_INET6;
   hints.ai_socktype = SOCK_DGRAM;
   hints.ai_flags = AI_ADDRCONFIG | AI_PASSIVE;

   char *address = 0;
   char *service = "4551";

   int ret = getaddrinfo(address, service, &hints, &res);

   printf("ret=%d\n", ret);

   freeaddrinfo(res);

   return 0;

}

Hello. I'm Softgear Ko.

Thank you for your comment. But It is still error. I did " svn co http://www.ibr.cs.tu-bs.de/svn/ibr-dtn/trunk/ibrdtn ibrdtn-svn " again. And I built them. I got the same error. Please check out.

Hi.

It looks like you grabbed a bad state of the source. Please checkout a fresh version and try again.

Hello.

I downloaded ibrdtn source code using SVN. I am using Ubuntu-10.04.4 64bit. Because of compile error, I added ‘#include “Configuration.h”’ into BundleCore.cpp. Afterthat, I got successful compile. However, When I run ibrdtn with default configuration (no touched ibrdtnd.conf from SVN), I get 'ibrcommon::socket_exception’ error.

So, I tried to debug this as the following. softgear@softgear-cube02:~/dtn/ibrdtn-svn$ gdb daemon/src/.libs/dtnd

Reading symbols from /home/softgear/dtn/ibrdtn-svn/daemon/src/.libs/dtnd...done. (gdb) r -c ibrdtnd.conf -d 1000

So, After I traced the source code, I found that getaddrinfo(address, service, &hints, &res) returned -2 in udpsocket::bind(const vaddress &addr) throw (socket_exception) in ibrcommon/ibrcommon/net/socket.cpp . At that time, address was NULL.

Could you help me?

Thanks in advance.
