I'm on Ubuntu 18.04. I'm trying to install EAGLE as instructed here. I've downloaded and unzipped the package and placed it in my home directory.

In the eagle folder, I run ./eagle run and got the following error:

$ ./eagle run
Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use:
   QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors.
   QT_SCREEN_SCALE_FACTORS to set per-screen factors.
   QT_SCALE_FACTOR to set the application global scale factor.
./eagle: symbol lookup error: /usr/lib/x86_64-linux-gnu/libGLX_mesa.so.0: undefined symbol: xcb_dri3_get_supported_modifiers

I tried running sudo ./eagle run and got this instead:

$ sudo ./eagle run
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
./eagle: symbol lookup error: /usr/lib/x86_64-linux-gnu/libGLX_mesa.so.0: undefined symbol: xcb_dri3_get_supported_modifiers

Using sudo wasn't mentioned in the instructions, but I tried it anyway. I'm not sure how I should deal with those 2 errors. How should I fix this to run EAGLE?

Update 1:

I tried running the following:

~$ dpkg -S /usr/lib/x86_64-linux-gnu/libGLX_mesa.so
dpkg-query: no path found matching pattern /usr/lib/x86_64-linux-gnu/libGLX_mesa.so

Update 2:

I ran some more commands:

~$ ldd Eagle | grep local
ldd: ./Eagle: not regular file
~$ lsmod | grep drm

  • Which video adapter and drivers do you use? Please install all upgrades with sudo apt-get update followed by sudo apt-get dist-upgrade to get newest dependencies on 18.04 LTS. And then retry to run EAGLE.

  • I ran sudo apt update; sudo apt upgrade but it still returns the same errors. Also, EAGLE worked just fine when I used it on Windows (purely Ubuntu now) so I don't think the hardware is the cause. Oct 12, 2019 at 13:32
  • Please execute ldd eagle | grep local on its folder and add output to the question. Are you using Nvidia or ATI/AMD video card? Please add output of lsmod | grep drm and lspci | grep -iE "VGA|Video|Graphics" to the question. On my 18.04 LTS system EAGLE works on Intel and on VM.

  • my Eagle folder is "Eagle" rather than "eagle" so I typed ldd Eagle | grep local instead Oct 13, 2019 at 6:01

1 Answer 1


Per the README

-- Linux Graphics Driver Issues Nouveau (Open Source driver for nVidia cards) may cause sporadic crashes during the login procedure.

Enable software rendering in libGL by setting LIBGL_ALWAYS_SOFTWARE to 1.

export LIBGL_ALWAYS_SOFTWARE=1 ./eagle

I ran


then ran the executable and it worked
