[TUTO] Build Qt to cross compile for arm
-
do you have any steps for cross compile qt5.5 for arm
-
QOpenglwidget file is included in my application..it is build on qt5.5. but giving file error while make using QT4.8 that QOpenGLWidget no such file.
-
Hi,
That's because QOpenGLWidget is a new class of Qt 5. Qt 4 has QGLWidget.
-
Thank for your valueable reply
-
i am trying to build qt5.5 for arm but getting error while build.
i am using ./configue -xplatform inux-arm-gnueabi-g++ command. it gives openssl error. openssl.h no such file?can you please suggest
-
Unless you specified that you want OpenSSL support it should not stop the build. If you want OpenSSL support then you need to provide that dependencies for your target.
-
DO you have any Build steps like QT4.8.5 for QT5.5?
-
That usually depends partly on the device you are targeting.

i am cross compiling qt for cubieboard 4.
can you please suggest me ./configure command ? -
I don't know this board but a quick search returns this blog entry which step 4 is likely what you are looking for to get started.

Hello. The above solution is working fine for no-opengl.
once opengl es2 enable for cross compile it gives opengl functionality test failed error. i have copied all the GL/GLES2 file from arm board to ubuntu pc and edit qmake.conf file. but it gives the same error.
how to cross compile qt for arm with opengl. can you please suggest? -
The headers are not enough, did you also copied the libraries ?

Hello,
I know this is a late reply, but hopefully someone is still reading this thread and active. I followed all the steps, and have everything setup. I compiled the file, but when I try and run the make I get an error saying their is no such file or directory of QGLWidget.
I am looking for assistance as to how I can rectify this problem, and finally get my applications building and running. I have included the terminal log below:/home/sam/Downloads/qt-everywhere-opensource-src-4.8.5/bin/qmake -spec qt-everywhere-opensource-src-4.8.5/mkspecs/qws/linux-arm-gnueabi-g++ CONFIG+=debug -o Makefile ../Qt5.0.2/5.0.2/gcc/examples/opengl/2dpainting/2dpainting.pro

Hi and welcome to devnet,
Are you trying to build a Qt 5 example with Qt 4 ?
-
So I am using the proper example now, it compiles, but when I run the make It says:
make: Nothing to be done for 'first'.
I have attached the entire command and response below:
sam@sam-VirtualBox:~/Downloads$ "/home/sam/Downloads/qt-everywhere-opensource-src-4.8.5/bin/qmake" '/home/sam/classwizard/classwizard.pro' -r CONFIG+=debug -spec /home/sam/Downloads/qt-everywhere-opensource-src-4.8.5/mkspecs/qws/linux-arm-gnueabi-g++
sam@sam-VirtualBox:~/Downloads$ make
make: Nothing to be done for `first'. -
Did you cross-compile Qt ? If so did you install it ?
-
-
Looks like you cross-compiled your application with Qt 4 and try to run it against Qt 5.
