Gentoo Installation

Post by bmckee »

I found an old thread on here for Gentoo Installation from 2015 but I'm having a different problem.

I have tried both a gentoo mono install and the picotech compiled mono and they both have the same problem:

Debug info from gdb:

warning: File "/usr/bin/mono-sgen-gdb.py" auto-loading has been declined by your `auto-load safe-path' set to "$debugdir:$datadir/auto-load".
To enable execution of this file add
        add-auto-load-safe-path /usr/bin/mono-sgen-gdb.py
line to your configuration file "/home/brian.mckee/.gdbinit".
To completely disable this security protection add
        set auto-load safe-path /

For more information about this security protection see the
"Auto-loading safe path" section in the GDB manual.  E.g., run from the shell:
        info "(gdb)Auto-loading safe path"
The file mono is looking for is actually installed in the correct directory (the same place that the ps6000 driver is loading from). But for some reason the code can't find it.

I've tried exporting LD_LIBRARY_PATH:

Code: Select all

export LD_LIBRARY_PATH="/opt/picoscope/lib:$LD_LIBRARY_PATH"
I'd appreciate any help anyone can offer. I really don't want to run picoscope in a windows 10 virtual machine.

Thanks.

Update: I needed to run ldconfig as root and the software started working, but I'm getting glib warnings which are slowing everything down.

Code: Select all

(PicoScope.GTK:6077): GLib-CRITICAL **: Source ID 3857 was not found when attempting to remove it
I'll google that next.

Hi bmckee,

Could you please post the result of the ls command on the /opt/picoscope/lib folder?

Did you follow all the steps from our webpage in order to configure the package manager and install PicoScope Beta for Linux?

Regards,
