tizen_tools

Tizen cross-compilation toolchain for building the Flutter engine.

Generating 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

For arm

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

For arm64 (optional)

Make sure you already have created a sysroot for arm64 (below) before running the following.

for f in $TIZEN_STUDIO/tools/aarch64-linux-gnu-gcc-9.2/bin/aarch64-linux-*; do
  b=`basename $f`
  cp $f toolchains/bin/aarch64-tizen-${b:8}
done

# FIXME: https://github.com/flutter-tizen/tizen_tools/pull/7#discussion_r611339789
ln -s aarch64-tizen-linux-gnu-ld toolchains/bin/ld

# FIXME: This should not be necessary.
cp -r $TIZEN_STUDIO/tools/aarch64-linux-gnu-gcc-9.2/lib/gcc/aarch64-tizen-linux-gnu/9.2.0/*.{o,a} \
  sysroot/arm64/usr/lib

For x86 (optional)

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

# FIXME: This should not be necessary.
mkdir -p toolchains/lib/gcc
cp -r $TIZEN_STUDIO/tools/i586-linux-gnueabi-gcc-9.2/lib/gcc/i586-tizen-linux-gnueabi \
  toolchains/lib/gcc

Generating a sysroot

Run build-rootfs.py to generate a sysroot for each target architecture. You have to re-generate the sysroot whenever this repo has been updated.

For arm (Tizen 5.5+)

sysroot/build-rootfs.py --arch arm

For different architectures (optional)

# For arm64 (Tizen 5.5+)
sysroot/build-rootfs.py --arch arm64

# For x86 (Tizen 5.5+)
sysroot/build-rootfs.py --arch x86

# For arm (Tizen 4.0)
sysroot/build-rootfs.py --arch arm \
--base-repo http://download.tizen.org/snapshots/tizen/4.0-base/latest/repos/arm/packages \
--unified-repo http://download.tizen.org/snapshots/tizen/4.0-unified/latest/repos/standard/packages \
--output arm_40

# For x86 (Tizen 4.0)
sysroot/build-rootfs.py --arch x86 \
--base-repo http://download.tizen.org/snapshots/tizen/4.0-base/latest/repos/emulator32/packages \
--unified-repo http://download.tizen.org/snapshots/tizen/4.0-unified/latest/repos/standard/packages \
