Re: [beagleboard] Re: Cannot properly ./configure to install Qt with eglfs and opegles2 support.

[jonnymo]

I've tried to set this up and I am seeing a similar issue.  I piped the
output to tee and a log file and found it is not able to locate a lib which
from what I can tell is there.

This is the configure statement I used:

./configure -no-gcc-sysroot -device linux-beagleboard-g++ -device-option
CROSS_COMPILE=~/development/beaglbone/bbbuild/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

/usr/local/qt5bbb -qt-zlib -qt-libpng -no-openssl -opengl es2 -eglfs -v |&
tee ~/development/beaglbone/bbbuild/config-bbgr.log


This is what I see in the log file:

/home/jomodev/development/beaglbone/bbbuild/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++

This seems to be what is causing the ending error for the ELS libs.

Note: -optimized-tools is not useful in -release mode.

You might need to modify the include and library search paths by editing
QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for
your platform.

sysroot/lib/arm-linux-gnueabihf/libsystemd.so.0 -> libsystemd.so.0.25.0*


Perhaps it is not looking under the sysroot/lib folder but I am not sure.

I did ensure the Opengl ES libs are installed on the Beaglebone and ran
rsync to bring in the changes to sysroot and the add the lib and include
ref in the qmake.conf file:

*~/opt/qt5bb/qt-everywhere-src-5.15.1/qtbase/mkspecs/devices/linux-beagleboard-g++/qmake.conf*

*# Extra stuff (OpenGL, DirectFB, ...)*
*QMAKE_INCDIR_EGL=

*QMAKE_LIBDIR_EGL=
'/home/jomodev/development/beaglbone/bbbuild/sysroot/usr/lib/arm-linux-gnueabihf/libGLESv2.so.2.1.0'*


I'm not sure why it is failing for the libsystemd.so.0 but will continue to
look.

Cheers,

Jon

Jon, i've looking the links you provided, in fact, i need how to make a 
configuration like this:

VC_LIBRARY_PATH = $$[QT_SYSROOT]/opt/vc/lib
VC_INCLUDE_PATH = $$[QT_SYSROOT]/opt/vc/include

QMAKE_LIBDIR_OPENGL_ES2 = $${VC_LIBRARY_PATH}
QMAKE_LIBDIR_EGL= $$QMAKE_LIBDIR_OPENGL_ES2
QMAKE_LIBDIR_OPENVG = $$QMAKE_LIBDIR_OPENGL_ES2

QMAKE_INCDIR_EGL= \
$${VC_INCLUDE_PATH} \
$${VC_INCLUDE_PATH}/interface/vcos/pthreads \
$${VC_INCLUDE_PATH}/interface/vmcs_host/linux
QMAKE_INCDIR_OPENGL_ES2 = $${QMAKE_INCDIR_EGL}
QMAKE_INCDIR_OPENVG = $${QMAKE_INCDIR_EGL}

QMAKE_LIBS_OPENGL_ES2   = -lGLESv2
QMAKE_LIBS_EGL  = -lEGL -lGLESv2
QMAKE_LIBS_OPENVG   = -lEGL -lOpenVG -lGLESv2

I think, please correct me if i'm wrong, i need to change the  in this 
folder:
sitara@workstation:/opt/qt5bbb/qt5/qtbase/mkspecs/devices/linux-beagleboard-g++$
 
ls
qmake.conf  qmake.conf.bkup  qmake.conf.edited  qmake.conf.save  
qplatformdefs.h
(Some of those files are backup while i'm testing)

So, right now, my qmake.conf file is:

# Extra stuff (OpenGL, DirectFB, ...)
QMAKE_INCDIR_EGL=
QMAKE_LIBDIR_EGL=
QMAKE_INCDIR_OPENGL_ES2 = $${QMAKE_INCDIR_EGL}
QMAKE_LIBDIR_OPENGL_ES2 = $${QMAKE_LIBDIR_EGL}
QMAKE_INCDIR_OPENVG = $${QMAKE_INCDIR_EGL}
QMAKE_LIBDIR_OPENVG = $${QMAKE_LIBDIR_EGL}

QMAKE_LIBS_EGL  = -lEGL -lIMGegl -lsrv_um
QMAKE_LIBS_OPENGL_ES2   = -lGLESv2 $${QMAKE_LIBS_EGL}
QMAKE_LIBS_OPENVG   = -lOpenVG $${QMAKE_LIBS_EGL}

I try to fill those blanks with my paths, but no one works.

I think,  i'm working with the wrong file, or using wrong paths.
Do i see changes in the config.log with differents paths? 
I search inside the log and when it shows the EGL error, only notice me 
that cant found the libraries on [ ] ,, and thats all, a pair of empty 
square brackets.

Again, thanks for the replies, i'm very glad to have someone to ask and 
talk, every site or forum with this troubles has at least a few years of 
inactivity.

Jeremias.

[jonnymo]

If they are doing cross compiling from a remote host, then should they not
be using the BB specific libs under sysroot and not the host OpenGL libs?

Re: [beagleboard] Cannot properly ./configure to install Qt with eglfs and opegles2 support.

['Jeremias Ramirez' via BeagleBoard]

Hi Jon, thank you for the reply.

Thanks for the link, the first may be useful later, when this works.
The mailing links, are unavailale for me.

About the QMAKE variables, I try to change the paths on qmake.conf within 
the beagleboard device folder, but i dont know if I'm doing it wrong or 
something else because the error doesn't seem to change.

At least my configurations doesn't aply to those empty [].
None of [libGLESv2.so libGLESv2.a] found in [] and global paths.

Do you know how to edit those paths inside the ./configure command line to 
be sure be applied?

Thanks for the link, the first may be useful later, when this works.
The mailing links, are unavailale for me.

Thank you very much for your time.

Did you install the EGL libs on the BB?  This link might be helpful.

Re: [beagleboard] Cannot properly ./configure to install Qt with eglfs and opegles2 support.

[jonnymo]

For EGLS on the Beaglebone, I found this site to be useful:
https://elinux.org/BeagleBoneBlack/SGX_%2B_Qt_EGLFS_%2B_Weston#QtQuick_.2B_EGLFS

These previous posts might be helpful to you as well:
https://mail.google.com/mail/u/0/?tab=rm&ogbl#search/eglfs/FMfcgxwHNDCsxVdDfLbmTGZpHNmfxJPC

https://mail.google.com/mail/u/0/?tab=rm&ogbl#search/eglfs/FMfcgxwDqTfbHNjgxpDXtlXccKJmMgCS

For the error you are seeing, do you have the QMAKE environment variables
set as the error suggests?  The should point to your sysroot location:

ERROR: The OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing
*QMAKE_INCDIR_OPENGL[_ES2]*,
*QMAKE_LIBDIR_OPENGL[_ES2]* and *QMAKE_LIBS_OPENGL[_ES2]* in the mkspec for
your platform.

[beagleboard] Cannot properly ./configure to install Qt with eglfs and opegles2 support.

['Jeremias Ramirez' via BeagleBoard]

Hello to everyone.
I'm Jeremias, from Argentina.
Recently I started working with the BBB and Qt software.
Tooks me a long time, but i finally be able to install it and make some 
tests.
But, i never can run an app using eglfs, when I run an Qt example project , 
i get:

Could not find the Qt platform plugin "eglfs" in ""

After a time, i see i never install so many things within the Qt 
installation, so i read a lot and i start over again.
But,  in the ./configure step, i got this error:

My configure:

sudo ./configure -no-gcc-sysroot -device linux-beagleboard-g++ 
-device-option 
CROSS_COMPILE=/opt/gcc-linaro-7.5.0-2019.12-x86_64_armv8l-linux-gnueabihf/bin/armv8l-linux-gnueabihf-
 
-sysroot /mnt/bbb-rootfs -opensource -confirm-license -optimized-qmake 
-reduce-exports -release -make libs -prefix /usr/local/qt5bbb -hostprefix 
/usr/local/qt5bbb -qt-zlib -qt-libpng -no-openssl -opengl es2 -eglfs -v

Error:

ERROR: Feature 'opengles2' was enabled, but the pre-condition 'config.win32 
|| (!config.watchos && !features.opengl-desktop && libs.opengl_es2)' failed.

ERROR: Feature 'eglfs' was enabled, but the pre-condition '!config.android 
&& !config.darwin && !config.win32 && features.egl' failed.

ERROR: The OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing 
QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for 
your platform.

Config.log snippet:

Trying source 1 (type makeSpec) of library opengl_es2 ...
None of [libGLESv2.so libGLESv2.a] found in [] and global paths.
None of [libEGL.so libEGL.a] found in [] and global paths.
None of [libIMGegl.so libIMGegl.a] found in [] and global paths.
None of [libsrv_um.so libsrv_um.a] found in [] and global paths.
  => source produced no result.

I'm really trying to fix it by myself, but i can't, i don't want to give up 
with this...

Thanks in advice for any reply.

It's not terribly relevant where the files are stored - it's hosting 
them that requires some thinking. E.g. googling for "amazon aws host apt

https://www.aptly.info. I can't vouch for any of them.

If you go the route of deb package and apt repository, I'd suggest 
reading chapters 5, 6 and  Debian Administrator's handbook
https://debian-handbook.info/browse/stable/ - this briefly explains how 
they are used.


https://wiki.debian.org/DebianRepository/Setup has some info on how 
repositories are set up. AWS-friendly Aptly is in there somewhwere.


Depending on your circumstances, you might want to look into creating a 
systemd service out of your application:

I've distributed custom software as deb packages hosted by a private apt 
repository (Sonatype Nexus OSS). Mass-updates got manually triggered via 
ansible (which required the aforementioned SSH jumphost).

You can do something similar - package your binaries as a deb package, 
host an apt repository and figure out how to trigger updates. Or you can 
roll your own update scripts and repo. Or you can search for third-party 
solutions. I assume most of the underlying problems are the same - a 
trigger mechanism, a hosted package repository, authenticated data pipe, 
service restarting, recovery from botched upgrades etc.
