Installing fail urcap-sdk- using install.sh

I have failed to install urcap-sdk- with the following messages.
So I could not build MyDaemon example. HelloWorld is OK.
I work under URSIm Starter-VMware Workstation 12 Player.

ur@ursim:~/urcap-sdk-$ ./install.sh

This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:

Anyway Currently Only Python MyDaemon works by commenting out the pom.xml in the following way.

Thanks taegon.ha! We were running into the exact same issue, but we’re not familiar with Maven, so this would have taken forever for us to figure out ourselves.

It looks like the root of the problem is that the VM included in the starter package is not ready to compile C++ daemons out of the box for a couple of reasons:

The urtool cross compiler included with the URCAPS SDK appears to be the wrong architecture for the VM, and may have some dependencies that are not satisfied as well.

While playing around with it, I also discovered that the tool “scons” which is required by the process to build the C++ daemon is also not installed. Installing it doesn’t help you unless you can also get the URTools cross compiler installed though.

Notice the SW 3.3.4 release on Friday December 16th.
There has been implemented a fix to the install script.
It will now ask whether you want to install the “UR Tool Chain”. Please note this is designed for running on 64-bit Linux distributions with Intel chip.


I’m running the newest URSim (3.3.4) and I ran into these same issues. Inserting the comment symbols <!-- and --> on lines 108 and 150, respectively, solved this problem perfectly.

Essentially, this problem is caused (as mentioned in a few different posts) by the fact that the C++ version of the daemon cannot properly compile due to how the VirtualBox file is set up.

Actually, MyDaemon fails whenever you load the URCap. I guess it just won’t work on the VirtualBox.

What are the necessary steps to get mydaemon working on the newest URSim 3.3.4?

I managed to install the cross compiler and build “mydaemon” sample after installing scons.
When I run the program, I get an error message coming from the program: “Could not set the title in the daemon process.” And the title is never set.
Is there a way to fix this? I’m in Ubuntu 14.04 64-bit, SDK 1.1.0-76, URSim 3.4.0-39.

EDIT: it works running URSim with sudo.

well, i tried commenting out this part in the pom, but now i get:
Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.1:exec (ursim-install-urcap) on project mydaemonswing: Result of /bin/sh -c cd /home/ur/sdk/sdk-1.9.0/samples/swing/com.ur.urcap.examples.mydaemonswing && cp target/mydaemonswing-1.0-SNAPSHOT.jar /.urcaps/com.ur.urcap.examples.mydaemonswing.jar execution is: ‘1’. -> [Help 1]

while installing the maven project. Are there any working daemon examples or a list of things i need for deploying a python daemon?
