[visualization] mdx Problem

[ditafaith]

Hi @hfattahi,
I am running cmd_3.sh on Ubuntu 22.04 to process ALOS data following the tutorial.
However, there is an error and I assume it related to mdx.py can't run properly due to missing library libicudata.so.58.
Any response is appreciated.

Did you add the mdx.py into system path?

[ditafaith]

I don't think it should be added to the system path since the mdx.py is part of ISCE2.
Currently, maybe I give comment on cmd_3 scripts where the mdx is executed.

Hi @Arctic-Ambrun do you have idea how to solve mdx problem ?
mdx command can't running due to missing file as mentioned in error message
mdx: error while loading shared libraries: libicudata.so.58: cannot open shared object file: No such file or directory

Hello, seems like I'm also facing this issue. Had a clean installation using CMAKE on the newest github commit and had a similar issue with the icu library. The specific error I'm getting is mdx: error while loading shared libraries: libicui18n.so.58: cannot open shared object file: No such file or directory. This happens when I type mdx into the command line.

Seems like it's trying to reference a very old version of the library. I haven't found the solution yet, perhaps it might work if I install using scons.

[ditafaith]

libicui18n.so.58 is quite old and it looks like Ubuntu no longer to maintain this package.
However, we still rely on mdx to grab fast visualize the results.
@yunjunz could you give some idea on this matters?

mdx works when I install using the conda package for version 2.6.3

[ditafaith]

It sounds confusing that previously you mention got same error, but last message mention it works. Which OS do you use?
I also use ISCE2 version 2.6.3 which is the latest one, but the error remains.

[SpiderPigzz]

Ah, the issue only arises for me if I compile with CMAKE using the newest commit on GitHub (Not v2.6.3).

However, if I don't compile and do installation using the packaged conda-forge isce2 library, it works fine. But I want to use the newest features that were added after 2.6.3.

For OS, I'm using Rocky Linux v8.7 (Green Obsidian)

@SpiderPigzz noted it, thanks for sharing your experience.
Anyway, I can solve it by copying 2 files both libicui18n.so.58 and libjpeg.so.9.
It can be #closed
