Native Compile of QT 5.12 on Raspberry Pi4
Unsolved
Installation and Deployment
-
I successfully compiled QT5.10.1 on raspberry PI3 with debian stretch natively and getting my PI4 next week .
What are the changes that i need to make in the qmake.conf and with my compile command to compile against the Cortex A72 instead of the A53 as well as OpenGL ES 3.0 instead of OpenGL ES 2.0 ?My PI3 qmake .conf:
# qmake configuration for the Raspberry Pi 3 include(../common/linux_device_pre.conf) QMAKE_RPATHLINKDIR_POST += $$[QT_SYSROOT]/opt/vc/lib QMAKE_LIBDIR_OPENGL_ES2 = $$[QT_SYSROOT]/opt/vc/lib QMAKE_LIBDIR_EGL = $$QMAKE_LIBDIR_OPENGL_ES2 QMAKE_LIBDIR_OPENVG = $$QMAKE_LIBDIR_OPENGL_ES2 QMAKE_INCDIR_EGL = $$[QT_SYSROOT]/opt/vc/include \ $$[QT_SYSROOT]/opt/vc/include/interface/vcos/pthreads \ $$[QT_SYSROOT]/opt/vc/include/interface/vmcs_host/linux QMAKE_INCDIR_OPENGL_ES2 = $${QMAKE_INCDIR_EGL} QMAKE_INCDIR_OPENVG = $${QMAKE_INCDIR_EGL} QMAKE_LIBS_EGL = -lbrcmEGL -lbrcmGLESv2 QMAKE_LIBS_OPENGL_ES2 = -lbrcmEGL -lbrcmGLESv2 QMAKE_LIBS_OPENVG = -lbrcmEGL -lbrcmOpenVG -lbrcmGLESv2 QMAKE_CFLAGS = -march=armv8-a -mtune=cortex-a53 -mfpu=crypto-neon-fp-armv8 QMAKE_CXXFLAGS = $$QMAKE_CFLAGS DISTRO_OPTS += hard-float DISTRO_OPTS += deb-multi-arch EGLFS_DEVICE_INTEGRATION= eglfs_brcm include(../common/linux_arm_device_post.conf) load(qt_config)This is how i compile it
