[Fixed] MasterPlan does not start on Ubuntu 18.04

I have tried to start MasterPlan both from the app, file manager (double-clicking), and from the terminal. When starting from the terminal, I get this error:

zsh: no such file or directory: ./MasterPlan

Performing the command readelf -d MasterPlan returned this:

Performing locate XXX where XXX is the name of the libraries that readelf returned as needed, all of the libraries can be found in standard places on my system.

Performing a lookup of the interpreter readelf -a MasterPlan | grep interpreter returned:

      [Requesting program interpreter: /usr/lib64/]

This can also be found on my system in the location requested.

My google-fu has run out of ideas to try, so hopefully this information is enough for you. Let me know if any more info is needed.


It is now failing because libc6 2.29 is not found on my filesystem. I have version 2.27, which I believe is the highest version that can be fetched from vanilla Ubuntu 18.04.

Is it possible to build MasterPlan with an older version of libc?


Yes, I am running libc 2.29, as I recall, on my system, so that might explain why it's not running on yours. My apologies, really! I can see about resolving this by either building with an older version of libc, or packaging my libraries up with the application. It'll take some time for me to look into these options and implement one, though, so please give me some time to work on this.

Thanks. Am looking forward to being able to use it!

OK, I tried packaging local copies of the libraries in along with the build for Linux - please try updating and let me know if it worked!

Any news?

Now I just get a segmentation fault when I try to run it.


This could be because the provided libraries are typically just symlinks to the actual binaries. On my system, performing the command locate spits out quite a few of locations, however, the important one is “/lib/x86_64-linux-gnu/”. Performing the command results in the actual binary that is used.

~$ readlink /lib/x86_64-linux-gnu/

Maybe when you package the libraries, include the binaries and create symlinks that match the expected name? Or rename the binaries to the expected name?

Hello! Sorry for the late reply; yeah, this is strange, and I'm getting the same result with an Ubuntu virtual machine. I'll probably just end up rebuilding off of an Ubuntu VM and seeing if that works. Sorry for the delay, and thanks for your patience.

If you have a GitLab account (or any account that provides you free minutes for CI/CD), it is possible to automate the build with an older version of Ubuntu and have it upload to itch.

With the latest update, it now runs.

Excellent, and apologies for the long wait; glad to hear that it's working for you! I'll probably investigate automating the builds, yeah; that way I wouldn't need to spin up virtual machines and boot up my Mac to build. Thanks a lot, again!
