Title: QOpenGLBuffer Errors
Post by: Baris on August 14, 2020, 11:14:17 AM

I am using Limereport as report tool in one of my project.

QT Version is: 5.9.3
Limereport Version: 1.5.35 & 1.5.1
Platform is: Windows (MinGW 32bit) and I use QML.
I also use QtChart and Sqlite too.

I build your pro and link these output libs to my project: limereportd, limereport, QtZintd and QtZint (I copy/paste dlls and includes to my libs path)

As like that

Code: [Select]

DEPENDPATH += $$PWD/libs \
              $$PWD/libs/include

INCLUDEPATH += $$PWD/libs \
               $$PWD/libs/include

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/libs/ -llimereport
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/libs/ -llimereportd
else:unix: LIBS += -L$$PWD/libs/ -llimereport


win32:CONFIG(release, debug|release): LIBS += -L$$PWD/libs/ -lQtZint
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/libs/ -lQtZintd
else:unix: LIBS += -L$$PWD/libs/ -lQtZint

But there is a strange behaviour.

If i run my project in debug mode it always gives these errors and UI not shown (only white screen)

Code: [Select]

QOpenGLBuffer::bind(): buffer not created
QOpenGLBuffer::allocate(): buffer not created
QOpenGLBuffer::release(): buffer not created
QOpenGLBuffer::bind(): buffer not created

QOpenGLBuffer::release(): buffer not created
QOpenGLShaderProgram: could not create shader program
QOpenGLShader: could not create shader
QOpenGLShader: could not create shader
shader compilation failed:
""

QOpenGLShaderProgram::uniformLocation(opacity): shader program is not linked
QOpenGLShaderProgram: could not create shader program
QOpenGLShader: could not create shader
QOpenGLShader: could not create shader
shader compilation failed:
""
If i don't include report pri (I made my own) which is links limeport, qtzint dlls and include files to my project, there is no problem.

If i run in release mode with limereport there is no problem also.

Do you have any idea?

Hi! Honestly, I have no idea why it happens. Could you create a sample and send me the sources?

I think this is caused by MinGW - 32 bit.

I tried (Maybe it's incorrect i don't know  :) )

Code: [Select]

Qt::AA_ShareOpenGLContexts
Then Charts gives:

Quote

"QtCharts": Cannot load library C:\Qt\Qt5.9.3\5.9.3\mingw53_32\qml\QtCharts\qtchartsqml2d.dll: Not enough memory resources are available to process this command.
