Having problem while trying to install OMNeT++ #380

Description

I tried to install OMNeT++ to use alongside with Eclipse MOSAIC through this guide: https://eclipse.dev/mosaic/docs/simulators/network_simulator_omnetpp/#installation-for-users

when I run this command: ./omnet_installer.sh \ --installation-type USER \ --omnetpp /path/to/omnetpp-5.5.1-src.tgz \ --inet /path/to/inet-4.1.1-src.tgz \ --federate /path/to/omnetpp-federate-23.1.zip

I get asked about some dependencies:

Are the following dependencies installed on the system? Libraries: libprotobuf-dev >= 3.7.0 libxml2-dev Programs: unzip tar bison flex protoc gcc python y Yes X No, abort installation

And I have both python2 and python3 but it says: ERROR 'python' required, but it's not installed. Please install the package (sudo apt-get install for Ubuntu/Debian) and try again.

I can't understand why it still asks me about it. (in the tutorial above the actual command executes ./omnet_install.sh, but the real file is ./omnet_installer.sh. It would be nice if someone corrected this too).

Steps to reproduce

The following lines are executed on my terminal (zsh): cd /bin/fed/omnetpp chmod +x omnet_installer.sh ./omnet_installer.sh \ --installation-type USER \ --omnetpp /path/to/omnetpp-5.5.1-src.tgz \ --inet /path/to/inet-4.1.1-src.tgz \ --federate /path/to/omnetpp-federate-23.1.zip y

Workaround

I did try to install python via terminal with apt, didn't work

Did solve it by running: sudo apt install python-is-python3

but when executing ./omenet_installer.sh I got an compilation error: src/util/ClientServerChannel.h:27:10: fatal error: ClientServerChannelMessages.pb.h: Arquivo ou diretório inexistente 27 | #include "ClientServerChannelMessages.pb.h" | ^~~~~~~~~~ compilation terminated.

Hi,

Did solve it by running: sudo apt install python-is-python3

yes, this would've been my suggestion, too. Unfortunately, the INET framework we are integrating currently relies on python2, thus expecting the command python to be available. When we have resources to look at an omnetpp/inet-upgrade, this issue might be obsolete, but until then the best solution is to install python-is-python3.
