  echo Syncing sources && cd $ANDROID_ROOT && repo sync --force-sync --fetch-submodules --no-clone-bundle --no-tags
#   repo sync 的参数：
# -j：开启多线程同步操作，会加快sync命令的执行速度。默认情况下，使用4个线程并发进行sync。
# -c, –current-branch：只同步指定的远程分支。默认情况下，sync会同步所有的远程分支，当远程分支比较多的时候，下载的代码量就大。使用该参数，可以缩减下载时间，节省本地磁盘空间。
# -d, –detach：脱离当前的本地分支，切换到manifest.xml中设定的分支。在实际操作中这个参数很有用，当我们第一次sync完代码后，往往会切换到dev分支进行开发。如果不带该参数使用sync， 
#               则会触发本地的dev分支与manifest设定的远程分支进行合并，这会很可能会导致sync失败。
# -f, –force-broken：当有git库sync失败了，不中断整个同步操作，继续同步其他的git库。
# –no-clone-bundle：在向服务器发起请求时，为了做到尽快的响应速度，会用到内容分发网络(CDN, Content Delivery Network)。同步操作也会通过CDN与就近的服务器建立连接， 使用HTTP/HTTPS的$URL/clone.bundle来初始化本地的git库， 
#                   clone.bundle实际上是远程git库的镜像，通过HTTP直接下载，这会更好的利用网络带宽，加快下载速度。

构建

• 终端输入bash进入
• bash环境下输入sfossdk，将进入Platform_SDK的chroot环境，也是构建镜像的环境，此时正常会出现如下菜单：

1) setup_scratchbox: sets up a cross compilation toolchain to build mer packages
2) fetch_sources: fetch android/mer sources
3) setup_ubuntuchroot: set up ubuntu chroot for painless building of android
4) test_scratchbox: tests the scratchbox toolchain.
5) modify_config: modify some config file; update git submodule.
6) build_hybrishal: builds the hybris-hal needed to boot sailfishos for $DEVICE
7) build_packages: builds packages needed to build the sailfishos rootfs of $DEVICE

• 输入setup_scratchbox，安装构建用的target和tooling。
• 输入setup_ubuntuchroot，安装用于构建内核、hybris-hal所用到的ubuntu chroot环境。
• 输入fetch_sources，将拉取源码。
• 输入modify_config，将做一些配置，详细看上面脚本或者"$HOME"/.mersdk.profile文件。
• 输入build_hybrishal，将构建hybris-hal/hybris-boot等。
• 输入build_packages，将构建SFOS镜像，建议手动分步执行。

注意事项 & 技巧

内核参数修改

内核构建完成后，请检查内核参数：

HABUILD_SDK $ cd $ANDROID_ROOT hybris/mer-kernel-check/mer_verify_kernel_config \ ./out/target/product/$DEVICE/obj/KERNEL_OBJ/.config

build droid-hal-device 时，会自动检查，可能会出现错误，某某参数应该如何如何，日志参考：https://fars.ee/P963
根据提示，修改内核配置：检查$ANDROID_ROOT/device/$VENDOR/*/BoardConfig*.mk中TARGET_KERNEL_CONFIG的值。必须修改error项目，修改完成后，重新编译内核。

然后修改/补充 对应的内核参数。

如果修改了内核

重新构建内核，请先清理一下

cd system/core && git clean -x -f -d && cd -
#重新进入ubu chroot环境： 
ubu
mka hybris-hal

如果修改了droid-configs

需要重新构建 droid-config;并手动安装,命令来自于rpm/dhd/helpers/build_packages.sh脚本

bp -c
sb2 -t $VENDOR-$DEVICE-$PORT_ARCH -m sdk-install -R zypper in droid-config-$DEVICE
bp -v 更新一下

如果修改了mw\external

重新编译，需要先清理

cd hybris/mw/gst-droid && git clean -xfd && cd -
cd hybris/mw/gmp-droid && git clean -xfd && cd -
cd external/droidmedia/ && git clean -xfd && cd -
bp -m
bp -g

手动装包，处理依赖

PLATFORM_SDK $
#命令来自rpm/dhd/helpers/build_packages.sh脚本
sb2 -t $VENDOR-$DEVICE-$PORT_ARCH -m sdk-install -R zypper in droid-config-$DEVICE
sb2 -t $VENDOR-$DEVICE-$PORT_ARCH -m sdk-install -R zypper in "pkgconfig(audiosystem-passthrough)"
sb2 -t $VENDOR-$DEVICE-$PORT_ARCH -m sdk-install -R zypper in "pkgconfig(libdroid-util)"

跳过开机教程

左上、右上、右下、左下 四个角挨个点一下

清理 Target

PLATFORM_SDK $
sdk-manage target remove $VENDOR-$DEVICE-$PORT_ARCH
sdk-manage tooling remove Sailfish_OS-$RELEASE

repo 同步单个项目

PLATFORM_SDK $
repo sync -c --force-sync --fetch-submodules --no-clone-bundle --no-tags kernel/xiaomi/cancro
#kernel/xiaomi/cancro  是 .repo/local_manifests配置中的path。当前同步前如果有存在，请先删除。

repo 同步失败

error: in `sync -d --force-sync --fetch-submodules --no-clone-bundle --no-tags`: revision refs/tags/android-10.0.0_r40 in platform/cts not found
# 解决办法：在根目录单独下载
repo sync platform/cts

straggler_files

• 添加

Checking for unpackaged file(s): /usr/lib/rpm/check-files /home/sandy/Sailfish/src/installroot
error: Installed (but unpackaged) file(s) found:
   /d
   /file_contexts.bin
   /property_contexts
   /sdcard
   /vendor


RPM build errors:
    Empty %files file /home/sandy/Sailfish/src/dtbo.files
    Installed (but unpackaged) file(s) found:
   /d
   /file_contexts.bin
   /property_contexts
   /sdcard
   /vendor
No journal files were found.
Failed to seek to cursor: Invalid argument

这个时候，就需要把相应的文件添加到 rpm/droid-hal-$DEVICE.spec文件中。

• 移除

File not found: /home/sandy/Sailfish/src/installroot/init.class_main.sh
    File not found: /home/sandy/Sailfish/src/installroot/init.mdm.sh
    File not found: /home/sandy/Sailfish/src/installroot/init.qcom.class_core.sh
    File not found: /home/sandy/Sailfish/src/installroot/init.qcom.syspart_fixup.sh

这个时候，就需要把相应的文件从 rpm/droid-hal-$DEVICE.spec文件中删除。

原理参考：rpmbuild

在线构建某一个项目

bp --mw=https://github.com/Sailfish-On-Vince/onyx-camera-settings-plugin

本地构建某一个项目

cd hybris/mw/
git clone https://github.com/sailfishos/mapplauncherd
#切到某tag
git checkout -b 4.2.2 4.2.2
bp -o -b hybris/mw/mapplauncherd

关闭selinux

修改BoardConfig.mk （ 例如device/xiaomi/whyred/BoardConfig.mk）文件中的cmdline：追加selinux=0；

修改kernel参数（例如kernel/xiaomi/sdm660/arch/arm64/configs/whyred-perf_defconfig）：追加内核参数CONFIG_SECURITY_SELINUX_BOOTPARAM=y。

停用birdzhang自定义源

需要编辑hybris/droid-configs/rpm/droid-config-vince.spec

# OTA via self-hosted repo needs to have all adaptation-community repos removed
#Conflicts: community-adaptation-testing     #屏蔽掉
#Obsoletes: community-adaptation-testin     #屏蔽掉

屏蔽掉这个源 hybris/droid-configs/sparse/usr/share/ssu/repos.d/20-repo.sailfishos.club.ini

Debug(telenet & ssh)

构建程序启用调试

PLATFORM_SDK $ 
sed -ri 's;#!/bin/bash$;#!/bin/bash -x;g' rpm/dhd/helpers/build_packages.sh
sed -ri 's;#!/bin/bash$;#!/bin/bash -x;g' rpm/dhd/helpers/util.sh

telnet

手机连接电脑 usb 后，设置一下对应的 usb 网卡的 IP 地址：

sudo ifconfig enp0s20f0u11 192.168.2.13

然后，连接手机(debug 模式，无法正常启动时）：

telnet 192.168.2.15 2323

如果 switch_root 失败，连接端口号使用 23:

telnet 192.168.2.15 23

导出启动日志：

telnet 192.168.2.15 2323|tee init.log
dmesg
journalctl --no-page
exit

清理log脚本cleanlog.sh：

#!/bin/bash
file=$1
perl -i -pe 's/\e[[\(][0-9;]*[mGKFB]//g' "$file"
sed -ri 's/\r$//' "$file"
sed -ri 's/^\r//' "$file"

ssh

正常启动时，使用 ssh 连接(密码在 开发者模式 界面）：

如果没有 journalcal 日志，需要修改一下配置：/etc/systemd/journald.conf:Storage=persistent

ssh 192.168.2.15|tee init.log
devel-su
dmesg
journalctl --no-page
/system/bin/logcat

强制保留telnet

刷完Sailfishos后，若能正常进入文件系统，默认关闭telnet服务，但也可以移除关闭telnet服务的脚本：进入twrp，使用adb shell连接进入系统:

rm data/.stowaways/sailfishos/init_disable_telnet
