GLIBC_2.38 not found error

[anyfoolcancount2one]

I have just installed apio (apio-linux-x86-64-1.0.1-20251024-debian.deb) on a new Ubuntu installation (24.04 LTS) and I receive an error message when simulating:

gtkwave --rcvar "splash_disable on" --rcvar "do_initial_zoom_fit 1" _build/default/dff_tb.vcd dff_tb.gtkw
/home/nigel/.apio/packages/oss-cad-suite/lib/libc.so.6: version GLIBC_2.38' not found (required by /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so) Failed to load module: /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so /usr/lib/x86_64-linux-gnu/gio/modules/libdconfsettings.so: undefined symbol: g_assertion_message_cmpint Failed to load module: /usr/lib/x86_64-linux-gnu/gio/modules/libdconfsettings.so /home/nigel/.apio/packages/oss-cad-suite/lib/libc.so.6: version GLIBC_2.38' not found (required by /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so)
Failed to load module: /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so

I'm not an experienced linux user, but as far as I can tell, this appears to be caused by the latest version of apio wanting to use a later version of GLIBC than my version of Ubuntu has installed. Is that correct?

Is there a solution to this? Am I doing something really stupid?

Thanks @anyfoolcancount2one, we will look into it.

Hi @anyfoolcancount2one, I tried to reproduce it on my Ubuntu box but gtkwave did work so let's try to compare settings and go from there. Please run the three commands below and post their output.

pio Packages Status
Command 'pio' not found, but can be installed with:
sudo apt install platformio

Because of the above message, I installed platformio, and now when I type pio Packages Status, I get the following message:

I did wonder whether pio Packages Status was a typing error and the command should have been apio Packages Status, but that also did nothing:

apio Packages Status
Usage: apio [OPTIONS] COMMAND [ARGS]...
Try 'apio -h' for help.

@anyfoolcancount2one, sorry, I meant apio and not pio. ;-) Please run apio packages list and post the result here.

BTW, apio was inspired by pio hence the similar name.

EDIT: Your ubuntu seems slightly newer than mine, I will try to upgrade mine and retest. However, it seems that you have GLIBC 2.39 on your system.

All Apio packages are installed OK.

Thanks @anyfoolcancount2one, that looks good.

To clarify, when you get the error, does gtkwave still opens and seems functioning normally or does apio aborts and exit without showing the waves?

I just noticed that I am getting the same error message but because gtkwave is fully functioning I ignored it. I am now upgraded to ubuntu 24.04.3 and don't remember if I got it also on 24.04.2.

This is what I get.

Hi @zapta,

Yes, I can still use GTKWave. In fact, what I did was to copy a gtkw file from another project to my current directory, and GTKWave seems quite happy to overwrite that. It seems to be just the initial file creation that causes the problem.
It's not the end of the world - I can work around it - but it's not right the way it is . . .

Regards, Nigel

Ok, now that it's reproduced here I can look into it. Thanks.

[zapta]

The issue was reproduce with the latest yosys release. Filed an upstream issue to the yosys team: YosysHQ/oss-cad-suite-build#181

[zapta]

The upstream issue was moved to here YosysHQ/oss-cad-suite-build#181

If this will not be addressed in a reasonable time, we can add temporary filters for these lines in apio/managers/scons_filter.py.
