[solution] Salome 9.7 universal on Debian unstable - "GUI library corresponding to the user action not found" on explode

Posted by gswicke at January 31. 2022

Hi, as quite a few users before, I got the "GUI library corresponding to the user action not found" error when trying to use the "explode" feature in the geometry workspace. The issue turned out to be a library version mis-match, where the universal binary expected an older version of libraries than the host system (Debian unstable). Here is what I did to debug and fix this:

 

First, I started a new shell in the SALOME-9.7.0-MPI directory:

 

```

# Set up Salome specific include paths etc, so that ldd finds Salome internal dependencies

source env_launch.sh

 

# Check which libraries / symbols are missing

ldd -r BINARIES-CO7/GEOM/lib/salome/libEntityGUI.so

```

 

This identified mismatches in libglib2.0-0, libpango-1.0-0, and libpangoft2-1.0-0, partly based on symbols that had been removed in newer versions. To fix this, I used Debian's package pages to manually fetch older versions from Debian stable (libglib2.0-0_2.66.8-1_amd64.deb, libpango-1.0-0_1.46.2-3_amd64.deb, libpangoft2-1.0-0_1.46.2-3_amd64.deb) to a directory.

 

```

> ls

libglib2.0-0_2.66.8-1_amd64.deb libpango-1.0-0_1.46.2-3_amd64.deb libpangoft2-1.0-0_1.46.2-3_amd64.deb

 

# Unpack each deb using `dpkg -x`

> for i in *.deb;do dpkg -x "$i" /tmp/unpack; done

 

# Unpacked libraries now in /tmp/unpack/usr/lib/x86_64-linux-gnu, copy them into the Salome install

cp -r /tmp/unpack/usr/lib/x86_64-linux-gnu/* BINARIES-CO7/system_dep/

 

# Double check dependencies, hopefully nothing is missing now

ldd -r BINARIES-CO7/GEOM/lib/salome/libEntityGUI.so

```

 

Hope this helps,

 

Gabriel

 

PS: Would it make sense to include these libraries in the next universal binary release?

Hi Gabriel,

thanks for your message. I don't quite understand the issue here. Which Debian distro are you using, such that we can check if the issue can be reproduced with our Debian nodes . Thanks
