qt cross compilation for raspberry pi: Cannot find GLESv2

Question

I am trying to compile qt 5.9 for my raspberry pi 3 compute module and I have been following mainly the online guide here (https://wiki.qt.io/RaspberryPi2EGLFS). So

Answer 1

This is the qmake.conf I used (it worked for me):

include(../common/linux_device_pre.conf)

QMAKE_LFLAGS           += -Wl,-rpath-link,$$[QT_SYSROOT]/opt/vc/lib
QMAKE_LFLAGS           += -Wl,-rpath-link,$$[QT_SYSROOT]/home/pi/qtdeps/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          = -lEGL -lGLESv2
QMAKE_LIBS_OPENVG       = -lEGL -lOpenVG -lGLESv2

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

# Preferred eglfs backend
EGLFS_DEVICE_INTEGRATION= eglfs_brcm

include(../common/linux_arm_device_post.conf)

load(qt_config)
