Linux/AM4378: enabling QT4.8.7 on AM437x - Processor SDK

Hello Shiv,

Here is the config file.
qmake.conf

Here is the configure command.
./configure -opensource -confirm-license -xplatform qws/linux-arm-g++ -prefix /usr -embedded arm -opengl es2 -plugin-gfx-powervr -plugin-mouse-tslib -no-rpath

Apply these two patches.

cd qt-everywhere-opensource-src-4.8.7
git apply 0001-Fix-missing-pvr2d.h-and-wsegl.h-header-in-SGX-SDK.patch
git apply 002_pvrqwswsegl.c.patch

Copy tslib.h file to ti-processor-sdk-linux-am437x-evm-05.01.00.11/linux-devkit/sysroots/armv7ahf-neon-linux-gnueabi/usr/include and extract libts.tar.xz in ti-processor-sdk-linux-am437x-evm-05.01.00.11/linux-devkit/sysroots/armv7ahf-neon-linux-gnueabi/usr/lib.

Export the tool-chain path and build.
export PATH=<absolute path to>/ti-processor-sdk-linux-am437x-evm-05.01.00.11/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/:$PATH
./configure -opensource -confirm-license -xplatform qws/linux-arm-g++ -prefix /usr -embedded arm -opengl es2 -plugin-gfx-powervr -plugin-mouse-tslib -no-rpath
make -j 8

Use INSTALL_ROOT to extract the binaries and libraries to a separate directory, then copy this directory to your board in /usr location.
make INSTALL_ROOT=~/qt4 install

Export QWS_MOUSE_PROTO to make the touch screen work and install these tslib touch screen libraries on your board.
root@am437x-evm:~# export QWS_MOUSE_PROTO=Tslib:/dev/input/touchscreen0
root@am437x-evm:~# opkg install tslib-conf_1.1-r0.arago1_armv7ahf-neon.ipk
root@am437x-evm:~# opkg install libts-1.0-0_1.1-r0.arago1_armv7ahf-neon.ipk
root@am437x-evm:~# opkg install tslib-calibrate_1.1-r0.arago1_armv7ahf-neon.ipk


You can add QT4.8.7 support to the latest Processor SDK  by using OE build system in this way.

$ sudo dpkg-reconfigure dash
(Select "No" when prompted)

Close the current terminal where you have executed dpkg-reconfigure dash command and open a new one.

$ sudo apt-get install git build-essential python diffstat texinfo gawk chrpath dos2unix wget unzip socat doxygen libc6:i386 libncurses5:i386 libstdc++6:i386 libz1:i386

$ tar -Jxvf gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf.tar.xz -C $HOME
