A shell script to build Tizen target #847

Closed leemgs closed 7 years ago

leemgs commented 7 years ago

I can find appropriate build scripts for Windows, iOS, Android, Raspbian, and Tegra at the below webpage.

Where can I find a build script in case that I want to build the Tizen target (https://www.tizen.org)?

Here is a case study to to build Caffe2 with Tizen 4.0.m1-based your own rootfs for yourself for ARMv7 little-endian architecture. We assume that you are planning to execute a Caffe2-based intelligent application on a Tizen 4.0/M1 based RPi3 reference board. Even though you do not have a real embedded device such as Raspberry Pi3, don't worry about it. You could build and run Caffe2 on Ubuntu 16.04 LTS X64 thanks to QEMU (Virtualization Type 2).

u16.04$> firefox http://download.tizen.org/releases/milestone/tizen/4.0.m1/tizen-base_20170520.1/repos/arm/packages/armv7l/

u16.04$> firefox http://download.tizen.org/releases/milestone/tizen/4.0.m1/tizen-unified_20170529.1/repos/standard/packages/armv7l/


* 2nd step: Make your own Tizen 4.0 rootfs (for ARMV7L architecture)

u16.04$> mkdir -p /work/tizen/snapshot-rpi3-armv7l u16.04$> cd /work/tizen/snapshot-rpi3-armv7l u16.04$> sudo cp /usr/bin/qemu-arm-static ./mytizenrootfs/usr/bin/ u16.04$> sudo chroot ./mytizenrootfs/ qemu-arm-static /usr/bin/bash


* 3rd step: Add repo files (both base and unified) for zypper-based package management
For checking the latest version of zypper, visit https://git.tizen.org/cgit/platform/upstream/zypper/

tizen4.0# cd etc/zypp/repos.d tizen4.0# mv *.repo /opt tizen4.0# vi ./tizen-unified-standard-release-base.repo [tizen-unified-standard-release-base] name=tizen-unified-standard-release-base enabled=1 autorefresh=0 baseurl=http://download.tizen.org/releases/milestone/tizen/4.0.m1/tizen-base_20170520.1/repos/arm/packages/?ssl_verify=no type=rpm-md gpgcheck=0

[tizen-unified-standard-release-debug-base] name=tizen-unified-standard-release-debug-base enabled=1 autorefresh=0 baseurl=http://download.tizen.org/releases/milestone/tizen/4.0.m1/tizen-base_20170520.1/repos/arm/packages/?ssl_verify=no type=rpm-md gpgcheck=0

tizen4.0# tizen4.0# tizen4.0# vi ./tizen-unified-standard-release-unified.repo [tizen-unified-standard-release-unified] name=tizen-unified-standard-release-unified enabled=1 autorefresh=0 baseurl=http://download.tizen.org/releases/milestone/tizen/4.0.m1/tizen-unified_20170529.1/repos/standard/packages/?ssl_verify=no type=rpm-md gpgcheck=0

[tizen-unified-standard-release-debug-unified] name=tizen-unified-standard-release-debug-unified enabled=1 autorefresh=0 baseurl=http://download.tizen.org/releases/milestone/tizen/4.0.m1/tizen-unified_20170529.1/repos/standard/debug/?ssl_verify=no type=rpm-md gpgcheck=0


* 4th step: Install additional package to build Caffe2

tizen4.0# zypper update tizen4.0# zypper install make strace cmake gcc binutils glibc cpp protobuf-devel git libstdc++*


* 5th step: Build Caffe2 (w/ ver. 0.7.0)
 * Note that you have to wait for a long time (in my case, +40 minutes) due to QEMU's limitation such as 1) No H/W virtualization for CPU and 2) software I/O emulation.

tizen4.0# cd /opt/caffe2 tizen4.0# git checkout v0.7.0 tizen4.0# mkdir build && cd build tizen4.0# cmake -DUSE_GFLAGS=OFF -DUSE_GLOG=OFF \ -DUSE_NNPACK=OFF -DRUN_HAVE_STD_REGEX=0 \ -DRUN_HAVE_POSIX_REGEX=0 -DHAVE_GNU_POSIX_REGEX=0 \ -DUSE_MPI=OFF -DUSE_OPENMP=OFF -DUSE_ROCKSDB=OFF \ -DUSE_LEVELDB=OFF -DUSE_LMDB=OFF -DBUILD_PYTHON=OFF \ -DUSE_GLOO=OFF -DUSE_OPENCV=OFF \ -DCAFFE2_CPU_FLAGS="-mfpu=neon -mfloat-abi=soft" \ ..


* Final step: Check a generated *.so files. Then enjoy Caffe2.!!!!
