No already StaMPS PS processing detected

[AllendePrieto]

Hi Alex!
in the "PS approach/Preparation" step, it gives me the following error:
"No already StaMPS PS processing detected”
and in the matlab environment:

Could it be related to the gcc version?

Hi,

Not exactly. This is related to the version of libstdc++. There is a version conflict between your Linux library and the library provided by MATLAB. My advice is to create a temporary symbolic link between the MATLAB library /usr/local/MATLAB/R2022b/sys/os/glnxa64/libstdc++.s.6 and the same library in your Linux.

Thank you! I have modified it and it still working, but the message is the same when I get to the Run key:

What can happen?

Hi,

What are the sizes of these files? I suspect that your PATCH 1 does not contain PS points.

Kind regards,

Alexis

These are the files and their size

This path does not contain PS points. Please modify the number of paths to avoid an empty patch.

Hi Alex.
I can't generate the PS points even though I change the number of paths (7x3) (8x4) ...etc...

What can happen?

Hi,

Sorry for my late reply. Can you try just one patch?

Kind regards,

Hi again!
It gives me the same result. It does not generate PS points and the message is the same "No already StaMPS PS processing detected". My gcc version is 11.3.0. I tried to change to the gcc-7 version and try again, but it returns the error: "E: Package 'gcc-7' has no installation candidate".
The solution proposed in the installation instructions link does not work for me at the moment. Do you know any other solution for this problem?

Hi,

StaMPS must be compiled with the version 7 of gcc/g++. What are your Linux version?

Kind regards,

is the version

Hi Alex.

I'm getting the same error too. I am using Ubuntu 20.04 and gcc 7.0. About 2 years ago, when I got a similar error while using StaMPS, I solved the problem using python version 2.7. Do you think it would work to build InSARenv in 2.7 environment?

Best regards.

Fixed!
I uninstalled the version I had and installed the gcc-7 and g++-7 version by following the instructions in
https://askubuntu.com/questions/1406962/install-gcc7-on-ubuntu-22-04

Thanks!!

Nice. Thanks for sharing your solution.
I will try right away
