Original question:

Building CCS Project using Jenkins -

Building CCS Project through Jenkins on Linux

Hi,

I have a project using TMS320F280049C microcontroller built in CCSv1040. I am now trying to setup a Jenkins pipeline to set up a CI/CD server. I was originally having trouble building the project through Jenkins but changing the write rights on the folder resolved that issue. Now even though my project is building, the Jenkins build is failing because of this error:

"Unable to init server: Could not connect: Connection refused

Eclipse: Cannot open display:

Eclipse:

An error has occurred. See the log file"

Below you can see that the project is building without any errors:

    Here is the log file mentioned in the error message.

    4174.log.txt

    Hello,

    The bulk of the errors in the log seem to be various permission errors with folder in the workspace and some of the generated makefiles in the project. Can you check that the permissions for those are ok also?

    Thanks

    Hi,

    Since I also want to understand what's happening, what part of the log file indicates permission errors? Is there any way to ensure that Jenkins has all the permissions to all the folders/files, etc so these issues don't occur? There is only one user on this computer..

    Also, so far as I understand, as long as the system doesn't try to open Eclipse i.e. just ends after the headless build step, the issue should be resolved. Is that an incorrect assumption?

    Thanks!

    I see many "permission denied" type messages:

    doing a search of "permission denied" in the log file yields many hits

    ensure jenkis has write permiisions to the project and workspace folders and subfolders

    The CLI build commands rely on several eclipse/cdt and ccs components. Is the build completely successful despite the errors?

    Thanks

    No the build is failing because Jenkins keeps trying to open display.

    I got one build to run successfully but I had to manually go the folders and change their permissions to 777 which allowed Jenkins access to everything. But this change in permissions can't be automated and every time a new project is cloned, the permissions will change. When the Jenkins build runs it runs as system:

    Started by user CI/CD Server
18:14:50 Running as SYSTEM
18:14:50 Building in workspace /var/lib/jenkins/workspace/Freestyle
18:14:50 The recommended git tool is: NONE
18:14:50 No credentials specified

    Why does SYSTEM not have read/write access to the folders?

    it looks like that error can also occur when there is no Xserver present.

    with what permissions was CCS installed with?

    I'm not running this in a Docker container. Should I do that?
    There's only one user on the this system, the one I'm using..

    Does it even make sense to do this CI pipeline this way? Would it be better to use a makefile even if it's the autogenerated one?

    What does "sudo password Jenkins" mean here?

    looks like he used the command to create a password for the jenkins account:

    https://stackoverflow.com/questions/25041125/default-jenkins-user-password

    Then he was able to log in with the jenkins account using that password and install CCS/SDK and so on...

    I don't have much experience with jenkins so unfortunately I am unable to provide much suggestions regarding best practices with building CCS projects via CLI via jenkins. I will see if I can find someone who has more experience to comment.

    Thanks
