tizen_tools

Tizen cross-compilation toolchain for building the Flutter engine.

How to generate toolchains

You need a Linux x64 host with Tizen Studio 4.0 or later installed. It is assumed that tizen-studio is installed in the default location (HOME), and the required package (NativeToolchain-Gcc-9.2) is already installed. Run the following commands in this directory to copy required files from tizen-studio to toolchains. Typically, you have to run this only once.

TIZEN_STUDIO=$HOME/tizen-studio

mkdir -p toolchains
cp -r $TIZEN_STUDIO/tools/llvm-10/* toolchains
cd toolchains/bin

# For arm
cp $TIZEN_STUDIO/tools/arm-linux-gnueabi-gcc-9.2/bin/arm-tizen-linux-gnueabi-gcc-9.2.0 .
for f in $TIZEN_STUDIO/tools/arm-linux-gnueabi-gcc-9.2/bin/arm-linux-*; do
  b=`basename $f`
  cp $f armv7l-tizen-${b:4:99}
done

# For x86
cp $TIZEN_STUDIO/tools/i586-linux-gnueabi-gcc-9.2/bin/i586-tizen-linux-gnueabi-gcc-9.2.0 .
for f in $TIZEN_STUDIO/tools/i586-linux-gnueabi-gcc-9.2/bin/i586-linux-*; do
  b=`basename $f`
  cp $f i586-tizen-${b:5:99}
done

cd ../lib
mkdir -p gcc
cp -r $TIZEN_STUDIO/tools/i586-linux-gnueabi-gcc-9.2/lib/gcc/i586-tizen-linux-gnueabi gcc

How to generate sysroots

Run build-rootfs.py to generate sysroots for arm (device) and x86 (emulator).

cd sysroot

./build-rootfs.py --arch arm
./build-rootfs.py --arch x86

git apply *.patch

The sysroot should be re-generated if any dependencies are added by future updates (git pull).
