Error when building NS-3-dev

[Sidoine Samo Djossi]

Greeting to all.

 I have been trying to install NS-3-dev unsuccessfully. After several attempt at the building stage I am always having this errors:

[ 835/2381] Compiling examples/udp-client-server/udp-client-server.cc

[ 836/2381] Compiling examples/udp-client-server/udp-trace-client-server.cc

cc1plus: error: unrecognized command line option ‘-std=c++11’

cc1plus: error: unrecognized command line option ‘-std=c++11’

Waf: Leaving directory `/home/samo/ns3/bake/source/ns-3-dev/build'

What to do about this. Thank you in advance.

For ns-3-dev (and the ns-3.26 or later release) you must use at least
gcc-4.8 (or clang-3.3) compilers. Ubuntu 12.04 default version is
gcc-4.6.

You should be able to find instructions on options for installing a more
recent gcc by searching on the web.

Thank you very much Mr Tom for your help. I have installed  gcc-4.8 I made it to be the default compiler and when I type gcc --version I have: 

gcc (Ubuntu 4.8.1-2ubuntu1~12.04) 4.8.1

Now when I try to build ns-3-dev again I still have 

[ 835/2381] Compiling examples/udp-client-server/udp-client-server.cc

cc1plus: error: unrecognized command line option ‘-std=c++11’

Waf: Leaving directory `/home/samo/ns3/bake/source/ns-3-dev/build'

Build failed

I still need your help Sir. Thank you Mr Tom in advance.

Try reconfiguring waf (rerun './waf configure ...') and if it still
doesn't work, please check whether your g++-4.8 is being used by
building with the '-v' option such as './waf build -v' and looking to
see how g++ is being invoked.

Thank you once more Mr Tom for your support. I have uploaded three screenshots. In the first screenshot, you will see how the gcc version 4.8 is indeed invoked. The two last screenshots show the continuation of the building process.

Hi,

instead of screenshots, could you copy the whole log and attach it ?

FYI, the terminal output can be saved as a text file (and can be copied too as a text file).

Thank you Sir for the remark. I will not repeat that.

Mine wasn't (only) a remark about the screenshots. It was a remark because I wasn't able to see the error. Nevertheless, I noticed it now.

The answer is here:

I hope this will help you in fixing the compilation issue.

Thank you infinitely Mr Tommaso. The NS-3-dev has been successfully built. Your help has always lead me to a breakthrough. Thank you for this priceless support.
