[Solved] Error building OMNeT++ 5.0 in Ubuntu 18.04

[Rayner Pires]

I have a fresh new installation of Ubuntu Bionic 18.04.1 LTS x64 (Linux 4.15.0-29-generic) and have to compile OMNeT++ 5.0 and INET 3.4.0 in order to continue a backed up omnet project.

This project has been used under Ubuntu Xenial 16.04.3 LTS x64 with those versions of OMNeT++ and INET.

The problem is that I cannot successfully compile omnetpp due to the following linker failure, and I am stucked because I could not trace back the problem:

(...)

I have the exact same error regardless I use CLANG or GCC/G++.

I followed the instructions at both 'omnetpp-5.0/doc/InstallationGuide.pdf' and InstallationGuide.pdf in order to compile OMNeT++ in my new OS, but neither of them helped me.

Anyone could help me, please? I've attached the output for 'configure' and 'make V=1' commands.

Hi,

You have followed installation guide of omnet 5.4.1.

Goto your doc folder inside omnet and use that installation guide.

Hi Rashmi Varma. Thank you for your answer.

I have followed both instructions (5.0 and the latest 5.4.3) but none of them mention a solution for this problem.

I have found one solution to compile OMNeT++ 5.0 in Ubuntu Bionic 18.04.1 LTS x86_64.

Following install guides from OMNeT++ 5.0 and 5.4.1, I got to compile the omnet library and IDE, as well as INET 3.4.0.

Because I do not need OSG and QT, I edited configure.user file and set the following variables to:

WITH_QTENV=no
WITH_OSG=no
QT_VERSION=5

Beside disabling Qt and Osg, it was still necessary to install some related package in order to get it compiled.

I installed:

sudo apt-get install build-essential gcc g++ clang bison flex perl python python3 qt5-default libqt5opengl5-dev tcl-dev tk-dev libxml2-dev zlib1g-dev default-jre doxygen graphviz libwebkitgtk-1.0-0 openscenegraph-plugin-osgearth libosgearth-dev openmpi-bin libopenmpi-dev

After that, I run

. setenv
./configure
make MODE=all base -j4

This way I did not compile the samples bundled within the tarball; only the library and the IDE, which are enough for my case.

I do not know why that happened, but since I have to use these versions of omnetpp and libinet, I am happy that it worked.

I hope it can help someone else.

Att.,
