Ports Not displayed and drone crashes.

[vin...@interfacemasters.com]

Hi All,
I recently installed ostinato 0.7 on my Ubuntu 15.10.
When i start the ostinato with "sudo ostinato" command its just starts the GUI and does not show the ports.
The reason i found out was the "drone" was not running when i did "sudo ostinato", which shld start both the client and server.
I manually started the drone using
case 1. "drone" command - result attached in text1.txt and does not crash or neither does show ports.
case 2. "sudo drone" -result attached in text2.txt and the drone crashes.

Even after the successful start of drone as in case 1 , I do not see any ports other than port as attached in screen shot.

I have tried to google this problem and i did not see any solution that could fix my problem.
Can i please get an help on this?

Case 1 - You don't see any ports because you need 'root' or sudo permission
Case 2 - Based on the logs, I'm not sure where it is crashing. If you
can build from source, build and run from gdb and let me know where it
crashes. I suspect it could be

Hi srivats,
I have tried to compile ostinato from source. I hope i have successfully installed the pre requisites before installing ostinato.
However when i try to execute the "make install" on ostinato. I have the following error.

I suspect that protobuf is throwing error. I do have protoc installed.

vinoth:~/protobuf$ protoc --version
libprotoc 2.6.1


Can you help me to proceed further.

What version of libprotobuf-dev did you install?

Did you use apt-get to install it or did you compile protobuf from source?

Srivats

[Vinoth Jagannathan]

I compiled protobuf from source using the instructions given in Link.

What is the topmost version in CHANGES.txt in your workspace? I
suspect it is 3.x - please verify and let me know.

To solve the problem for now, do this -
1. Run a 'sudo make uninstall' in your protobuf workspace to remove
what was installed earlier
2. Run 'sudo apt-get install libprotobuf-dev' to install the package
3. If protoc is not available, run 'sudo apt-get install protobuf-compiler'

Let me know if that works.

Yes the version was 3.0.0. I undid the source compilation and did the sudo installations.

My protoc version is libprotoc 2.6.1.

Now i have this following failure .

Do a "make distclean" followed by "qmake" and "make" and see if the
problem goes away.

btw did you install protobuf-compiler using apt-get?

Srivats,

Apologies for late reply.
Yes i installed protobuf-compiler via apt-get.
I was able to install ostinato and drone. Both files are available in  /usr/local/bin.
When i do a sudo ostinato i still don't see drone running and i face the same problem which i initially stated in the post.

Thanks
VJ

Vinoth,

Can you apply the below patch, build from source and let me know if it
fixes the problem -
