Failing to compile OpenMW on ARM

Post by bably » 24 May 2019, 23:24

Hi everyone :)

I've been trying to run openmw on my ARM laptop these past few days.
It's an ARMV7L, running Ubuntu 16.04.6 in a chromebook, using crouton.

I cloned the repo a few hours ago, the last commit that shows up w/ git log is: Merge branch '2' into 'master' (e0fb411fc80f50d32fd98dcbef5c8974b1b25af7)

I managed to get all the dependencies and get past the config part, the cmake log shows the following text:

Code: Select all

However, when I run the "make" command, I get the following error:

If it helps anyone, I've found a very similar error from this 2016 bug report:
https://bugs.debian.org/cgi-bin/bugrepo ... bug=838792

Should I try to compile another release from the repo?
Any help would be greatly appreciated!

We're likely to totally abandon Qt4 support as soon as we get around to making the necessary changes, so I'd start by upgrading to Qt5 and seeing if that fixes anything.

Re: Failing to compile OpenMW on ARM

Hey AnyOldName3,

So, I've purged Qt4 and installed Qt5, but the cmake step now tells me I need Qt4 instead of Qt5...
I get the following output:

Code: Select all

-- Configuring OpenMW...
-- Using Qt4
CMake Error at /usr/share/cmake-3.5/Modules/FindQt4.cmake:1326 (message):
  Found unsuitable Qt version "5.5.1" from /usr/bin/qmake, this code requires
  Qt 4.x
Call Stack (most recent call first):
  CMakeLists.txt:157 (find_package)


-- Configuring incomplete, errors occurred!
Any ideas?

Run cmake with:

Thanks Miroslav, I was able to get pas the cmake step with that argument.

However, I'm still stuck at the same point once I run make, with a slightly different message:

Are you maybe mixing up a GLES GL.h and a regular OpenGL build of OSG/Qt or vice versa?

I don't remember messing around with OpenGL or OpenGLES, but it could be.
Is there any way to check if this is the case?

I'm no expert, but it looks like Qt has its own version of OpenGL (qopengl), which is clashing with the one used by OSG.

I'll try with a fresh crouton install in the meanwhile.
Update: having the same error with a fresh install

By digging around some more, I think that this is actually a bug within OpenGL and not OpenMW...
From what I understood from the last link, it looks like this bug was fixed in Mesa 18.2.5, but mine is still 18.0.5 (is there a way to update this?).

https://github.com/KhronosGroup/OpenGL- ... issues/162
https://bugs.freedesktop.org/show_bug.cgi?id=105328
https://marc.info/?l=mesa3d-dev&m=154219246303000&w=2

I'll try the workarounds they listed tomorrow, with my fingers crossed.

So, I've dedicated some time to this today, and got a bit ahead in the process.
I found out I could get a new version of the mesa drivers if I updated my chroot from Ubuntu 16 to 18, and that's what I did.
This allowed me to get the mesa drivers versions 18.2.8, where the bug I was having had already been fixed.

With this, I was able to compile openmw correctly (yay!), using Qt5 (Qt4 still gave me a similar error).
I now have another problem, but it's a crash happening when I launch the game, so I figure I should make another thread about it.

Did you definitely recompile everything and make sure all your packages were compatible with the updated Mesa? It's possible some old stuff was still hanging around.
