qtbase compilation error with --device linux-rasp-pi3-g++ qeglfskmsgbmwindow.cpp
-
Hello. I'm new to compiling qt myself and I'm trying to compile qtbase for raspberry pi and I have compilation errors in file qeglfskmsgbmwindow.cpp. I think that maybe some eglfs source files changed with new raspbian stretch or something like that. Please point me in some direction how to fix it.
I'm following tutorial from https://wiki.qt.io/RaspberryPi2EGLFSTechnical information:
device: Raspberry PI 3 B with Raspbian Stretch. apt uptade, apt upgrade and rpi-update done.
QT: 5.11 from GIT

@ronperek Are you trying this in a clean build directory? The issue may be a mix of the old EGL stuff and the freshly updated not being realized by the new build.
-
@ambershark Yes. I clean the build directory before each try.
To my understanding, the problem I have is that the qt developers have another version of EGL library than I have on raspberry.
I found missing declarations in sysroot/usr/include/EGL/eglext.h - version from 2016-08-09
but qt uses sysroot/opt/vc/include/EGL/eglext.h - version from 2009-01-20I replaced EGL from opt/vc/include with EGL from usr/include but now I have different problem:
/home/ron/raspi/qtbase/src/plugins/platforms/eglfs/deviceintegration/eglfs_brcm/qeglfsbrcmintegration.cpp:74:5: error: ‘EGL_DISPMANX_WINDOW_T’ was not declared in this scopeOf course missing declaration is present in 2009 version and removed in 2016 version.
Am I the first one trying to compile QT 5.11 for Raspberry PI 3 with Raspbian Stretch?
Do you have some tutorial to get full QT 5 working on PI?
-
@ronperek Yea it definitely sounds like an issue of mixing EGLs. From what I recall last time I built Qt is that you could specify whether to use Qt's version or your own for most components which I would assume (big assumption here) applies to EGL as well. It's possible you can just point it at the EGL to use so you can make sure your Pi and build machine have the same EGL.
I don't have a tutorial on getting Qt5 running on a Pi. I've never actually done it. I have done a decent amount of cross compiling though so I've helped a lot of people get their builds running for Pi on these forums (which you can search). Some of them listed tutorials but I didn't pay enough attention to them to remember.
As for being the first one to build, you may be. :) 5.11 is in beta so it's possible you are on bleeding edge that just hasn't been thoroughly vetted yet.
Also this:
I replaced EGL from opt/vc/include with EGL from usr/include but now I have different problem
will never work. You definitely don't want to just replace includes like that.
It sounds like you just need to force Qt (via configure) to use the version of EGL you want. However be warned you'll have to have that one compiled for your Pi in order to have Qt build with it.
-
I finally managed to get it compiled. I know it's not the pretty solution and that this may get back at me sometime, but for now it works.
I run "make" with 2009 EGL version in place, then i replaced it with 2016 EGL version and run "make" again to compile file that failed. Finally I restored 2009 EGL.
-
@ronperek Yea that's most definitely going to bite you, lol. I wish I could have helped you solve your problem I just haven't done that compile so my advice was just some guesses.
Hopefully it works out for you, but I wouldn't feel confident distributing it like that. If it's for in house developers/user or just yourself then that's ok but if that goes to customers you will have some issues to deal with.

When i add this line:
typedef EGLSurface (EGLAPIENTRYP PFNEGLCREATEPLATFORMWINDOWSURFACEEXTPROC) (EGLDisplay dpy, EGLConfig config, void *native_window, const EGLint *attrib_list);after all include in file src/plugins/platforms/eglfs/deviceintegration/eglfs_kms/qeglfskmsgbmwindow.cpp compile was finished great.
