Cross Compilation issue for qt
-
Yes. I have installed the cross compiler for STM. I am able to cross compile helloworld program and run on Target.
I have one doubt. This method with configure, make, make install, do i have to move the built files to my Target? or it creates cross compiler with qt on host PC?
@upendar25 take a look at section Qt Creator from RaspberryPi2EGLFS guide to grasp an idea of how "Qt Creator can be set up to build, deploy, run and debug Qt apps directly on the device with one click"

@raven-worx This helloworld program uses GTK module and built by creating a makefile. It works fine. But i am unable to build the same with Qt5. Forthis i need Qt libraries and toolchain to compile qt applications.
I have downloaded the qt source and tried to configure for my device. But got the below error.

@upendar25 said in Cross Compilation issue for qt:
I am not sure of sysroot. How to find it for a device?
a sysroot is a directory structure, similiar to a separate Linux root
/structure. Normally this comes along with the cross compiler. It contains the libs for the traget platform the cross-compiler should link against.modifications to g++.conf
modifications to g++.confyou are overwriting the compilers. Are those really globally accessible?
linux_device_pre.conf already contains:
QMAKE_CC = $${CROSS_COMPILE}gcc QMAKE_CXX = $${CROSS_COMPILE}g++ QMAKE_LINK = $${QMAKE_CXX} QMAKE_LINK_SHLIB = $${QMAKE_CXX}Which already produces the calls you need with the CROSS_COMPILE variable i suggested.
I dont know if the cross compiler needs any special parameters/flags? If so only define those within this minimal device:
include(../common/linux_device_pre.conf) # QMAKE VARIABLE MODIFICATIONS HERE include(../common/linux_arm_device_post.conf) load(qt_config)Make sure you set the
CROSS_COMPILEvariable (like you already do). -
@upendar25 said in Cross Compilation issue for qt:
I am not sure of sysroot. How to find it for a device?
a sysroot is a directory structure, similiar to a separate Linux root
/structure. Normally this comes along with the cross compiler. It contains the libs for the traget platform the cross-compiler should link against.modifications to g++.conf
modifications to g++.confyou are overwriting the compilers. Are those really globally accessible?
linux_device_pre.conf already contains:
QMAKE_CC = $${CROSS_COMPILE}gcc QMAKE_CXX = $${CROSS_COMPILE}g++ QMAKE_LINK = $${QMAKE_CXX} QMAKE_LINK_SHLIB = $${QMAKE_CXX}Which already produces the calls you need with the CROSS_COMPILE variable i suggested.
I dont know if the cross compiler needs any special parameters/flags? If so only define those within this minimal device:
include(../common/linux_device_pre.conf) # QMAKE VARIABLE MODIFICATIONS HERE include(../common/linux_arm_device_post.conf) load(qt_config)Make sure you set the

I did these changes. But still there seems to be a problem with configure options.

@raven-worx Surprisingly no. It says no file or directory. But i have that file in that location. I have reinstalled the cross compiler SDK.
I am able to cross compile using a makefile running it in the SDK environment. But separately with this g++, i am unable to compile a cpp file.

@raven-worx I think so. But i am unable to figure it out.
I have done the following steps.
Hardware: STM32MP157c-DK2 with Cortex A7 and M4
SDK is installed : https://wiki.st.com/stm32mpu/index.php/STM32MP1_Developer_Package#Installing_the_SDK
Qt12.3 : https://download.qt.io/archive/qt/5.12/5.12.3/single/qt-everywhere-src-5.12.3.tar.xz
Configure command: ./configure -release -opengl es2 -opensource -confirm-license -device stlinux-arm-gnueabi-g++ -device-option CROSS_COMPILE=/home/upendar/STM32MPU_workspace/STM32MP15-Ecosystem-v1.0.0/sysroots/x86_64-openstlinux_weston_sdk-linux/usr/bin/arm-openstlinux_weston-linux-gnueabi/arm-openstlinux_weston-linux-gnueabi- -sysroot home/upendar/STM32MPU_workspace/STM32MP15-Ecosystem-v1.0.0/sysroots/x86_64-openstlinux_weston_sdk-linux -v
.if someone can point my mistake, it would help me a lot.
Thank you!

@upendar25
i mean the path is obviously wrong when you can't execute it.
Check it directory by directory and you will find the mistake. Once you found it adapt the CROSS_COMPILE parameter accordingly.
