I have been trying to cmake upm for some days now. The most recent error log and cmake output files are attached below:

Also, the terminal output is as follows:

Any suggestions will be appreciated.

Hi @mrsandeshbhat this might be caused by a dirty build directory. Do you have any files in it? I recommend deleting it and creating it again before running cmake.

Hello @Propanu I tried deleting the upm folder using (rm -R upm) and running cmake again. I am getting the same error. Do you have any idea as to why this might be happening?

[mrsandeshbhat]

Fixed it!!

Before the solution, here is what I tried and failed at:

1. delete the build directory and cmake again - failed.
2. delete the upm directory, git the upm directory and cmake again - failed.
3. re-flash the jubilinux OS and try all that again - failed.

Now here is what worked:

I flashed a ubilinux OS on my board and then reflashed it with the jubilinux OS and tried it again.

The cmake seems to fail if the OS had some of the dirty files from a previous build attempt and even a fresh OS install install didn't help it. But now it works.
