proj has to be installed as libproj0. You also need to install libgdal-dev package.

sudo apt-get install build-essential gcc g++ bison flex perl tcl-dev tk-dev blt libxml2-dev zlib1g-dev default-jre doxygen graphviz libwebkitgtk-1.0-0 openmpi-bin libopenmpi-dev libpcap-dev autoconf automake libproj0 libgdal1-dev libfox-1.6-dev libgdal-dev libxerces-c-dev

Background info

I am trying to install Veins simulation environment by following the tutorial provided by the author.

In step 1 it is required to install some packages in Linux, the tutorial suggest this commands to be executed on Terminal:
```
sudo apt-get install build-essential gcc g++ bison flex perl tcl-dev tk-dev blt libxml2-dev zlib1g-dev default-jre doxygen graphviz libwebkitgtk-1.0-0 openmpi-bin libopenmpi-dev libpcap-dev autoconf automake libtool libxerces-c2-dev proj libgdal1-dev libfox-1.6-dev
```
When I execute this command, I immediately get:
```
E: Package 'proj' has no installation candidate
```
Then I remove the proj from the command and execute it again without proj in it, next I get:
```
The following packages have unmet dependencies:
 libgdal1-dev : Depends: libgdal-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
```
So, I remove libgdal1-dev from the command as well. And it executes file, by downloading the remaining packages.

To troubleshoot the problem with proj and libdgal1-dev I go to the Synaptic Package Manager.

libgdal1-dev

I search for libgdal1-dev in Synaptic Package Manager and I get an entry. I Mark for Installation and then Synaptic Package Manager suggests removing libxerces-c2-dev which is actually added via the initial command. Should I trust Synaptic Package Manager with this suggestion, and proceed further?

proj

What should I do about proj. There are some packages in Synaptic Package Manager such as proj-bin or libproj-dev. Should I install them? I think proj has to do with this and this

What should I do to make sure that this simulation tool works fine?

do I need to re-compile the software after installing new packages?

executing your command, returns The following packages have unmet dependencies: libgdal-dev : Depends: libxerces-c-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages.

add libxerces-c-dev also to the list. I edited the answer.

after the last update to the command the Terminal returns: The following packages have unmet dependencies: libxerces-c-dev : Conflicts: libxerces-c2-dev but 2.8.0+deb1-3build1 is to be installed libxerces-c2-dev : Conflicts: libxerces-c3-dev E: Unable to correct problems, you have held broken packages.

remove libxerces-c2-dev package.
