Qt6 OpenGL Static Release. Error: qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glMatrixMode'

8Observer8

Hello,

I have Qt 6.2.0 MinGW 64bit with a static build. The dynamic debug build works fine (as the dynamic release) but the static release build does not work:

qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glMatrixMode'
qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glLoadIdentity'
qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glOrtho'
qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glLoadMatrixf'

I use QOpenGLFunctions:

.pro:

QT       += core gui openglwidgets

win32: LIBS += -lopengl32

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

you dont have the right lib file path in ur pro file
just check it very carefully ,u'll find the secret of the way

Which path? But why does the dynamic version work?

Christian Ehrlicher

glMatruxMode is defined in OpenGL32.dll so you have to link against OpenGL32.lib as described in the documentation.

8Observer8

@Christian-Ehrlicher how to link OpenGL32.lib? What must I write in pro file?

What must I write in pro file?

LIBS

8Observer8

@Christian-Ehrlicher as you can see in my first post I have written in my pro file:

win32: LIBS += -lopengl32

8Observer8

Maybe should I include -opengl (or something like this) to config command before the static build?

configure -prefix "C:\Qt6.2.0_Static" -static -static-runtime -release -opensource -confirm-license -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -opengl desktop -sql-odbc -sql-sqlite -nomake tools -nomake examples -nomake tests -skip qttools -skip qtquick3d -skip qt5compat -skip qtquicktimeline -skip qtwebengine -skip qtactiveqt -skip qtcharts -skip qtconnectivity -skip qtdatavis3d -skip qtimageformats -skip qtlottie -skip qtnetworkauth -skip qtremoteobjects -skip qtvirtualkeyboard -skip qtserialbus -skip qtserialport -skip qtwebchannel -skip qtwebview -skip qtwayland -skip qtscxml -skip qtmqtt -skip qtopcua -skip qtsvg -skip qtdoc -skip qttranslations

as you can see in my first post I have written in my pro file:
win32: LIBS += -lopengl32

Then make sure this also appears in your linker line when linking the executable.

8Observer8

I see -lopengl32 in this line: C:\Qt6.2.0_Static\lib\objects-Release\QWindowsIntegrationPlugin_resources_2\.rcc\qrc_cursors.cpp.obj -limm32 -loleaut32 -lshlwapi -lwinspool -lwtsapi32 -lopengl32

Ok - please take a look at this answer: https://stackoverflow.com/questions/9336263/glfw-undefined-references

Looks like MinGW split up the libs different to MSVC.

Also you can try to move -lopengl32 after all the other libs (for testing purposes directly on the command line)

I tried to delete this line win32: LIBS += -lopengl32:

QT       += core gui openglwidgets

I tried to place it at the end:

But the result is the same. It compiles without errors for dynamic version of Qt (both for Debug and Release) and it does not work for static release only.

@8Observer8 said in Qt6 OpenGL Static Release. Error: qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glMatrixMode':

I tried to delete this line win32: LIBS += -lopengl32:

Why? Did you read my post, the so post and what I suggested?

I tried removing this line as an experiment to see if there would be more errors, but the number of errors remained the same. This is some kind of mystic. It's as if the linker is ignoring -lopengl32

@8Observer8 said in Qt6 OpenGL Static Release. Error: qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glMatrixMode':

Maybe should I include -opengl (or something like this) to config command before the static build?

Here is -opengl

@Christian-Ehrlicher said in Qt6 OpenGL Static Release. Error: qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glMatrixMode':

Why? Did you read my post, the so post and what I suggested?

Yes, I did. For example, I tried this: In the linker, at Windows, MinGW: -lglew32 -lglfw3 -lopengl32 -lglu32 -lgdi32 But I do not use GLFW and GLEW. I tried these keys: lglu32 -lgdi32. I made a simple example in OpenGL. It compiles without errors for dynamic version of Qt 6.2.0 (both: for Debug and for Release builds) but it does not compile for static release only. Errors:

qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glMatrixMode'
qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glLoadIdentity'
qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glOrtho'
qopenglpaintengine.cpp:-1: error: undefined reference to `__imp_glLoadMatrixf'

QT       += core gui openglwidgets

What else should I try?

I tried putting -lopengl32 at the end of the line: win32: LIBS += -lglu32 -lgdi32 -lopengl32

I tried to create a question on StackOverflow: Failed to build OpenGL project with static Qt 6.2.0 but my question was closed as duplicate:

This question already has answers here:
What is an undefined reference/unresolved external symbol error and how do I fix it? (38 answers)

If anyone encounters this problem and solves it, then please write here how you solved this problem. I did everything I could.

Probably you have to add the path to the libraries like this (in case the libs are in your project working dir):
LIBS += -L$$PWD -l<blah>
At least this helped me, as I had to add a lib to my project.
