compiling as shared library fails (err 42)

[TiTou]

We have a LabVIEW 2020 SP1 project on Linux that compiles well on Ubuntu 20 (not officially supported)

We compile as an application and also as a shared library
We use the application (with UI) for test and debug and in production we run the shared library as a service

We do not use any DAQ or any other NI driver

We moved to CentOS 8 (officially supported), fresh install of LabVIEW 2020 SP1 and here the application compiles well but the compiling as a shared library fails, the compilation process runs till the end (or seems to) and then returns the following error :

Error 42 occurred at System Exec.vi. Command was "gcc -m64 -shared -g  -O2 -fPIC -Wl,-Bsymbolic -I/usr/local/natinst/LabVIEW-2020-64/cintools "synchrohub.c" /usr/local/natinst/LabVIEW-2020-64/AppLibs/lvdll.a  -o "synchrohub.so" -lstdc++ -ldl"

Any one has any idea what the issue could be?

it appears that the system exec.vi just doesn't work, even in the IDE

and therefore fails when the build process calls it

as shown below, the system exec.vi is runnable but fails with error 42, whatever cmd I try to run :
