fuchsia學習_下載下傳編譯遇到問題和demo運作

下載下傳編譯,官網 https://fuchsia.dev

$ curl -s "https://fuchsia.googlesource.com/fuchsia/+/master/scripts/bootstrap?format=TEXT" | base64 --decode | bash

$ export PATH="/home/fuchsia/.jiri_root/bin:$PATH"

$ fx set core.x64 --with //bundles:kitchen_sink

$ fx build

$ fx emu -N

// 模拟器運作起來後,可執行指令:

$ printf "1234"  $ pwd  $ ps  $ date  $ ls  $ uname  $ uname -srm  $ locate

https://fuchsia.dev/fuchsia-src/getting_started

$ fx get-device-addr

====

遇到問題五(shasum指令問題):

$ fx qemu -N

"$errmsg" is not exported by the Digest::SHA module

Can't continue after import errors at /usr/local/bin/shasum line 21.

方案參考  https://command-not-found.com/shasum

$ sudo apt-get install libdigest-sha-perl

驗證指令方式  $ shasum --help

====

遇到問題四(ubuntu18的KVM權限問題):

$ fx qemu -N

qemu-system-x86_64: failed to initialize KVM: Permission denied

方案參考  https://stackoverflow.com/questions/59131434/unable-to-start-fuchsia-on-emulator

$ sudo chmod 777 /dev/kvm

====

遇到問題三(運作虛拟機):

$ fx qemu

ERROR: Could not extend fvm, unable to stat fvm image

問題解決(原因是非英文系統會遇到):

方案參考 https://github.com/assusdan/fuchsia-patches 或 https://forum.fuchsia-china.com/t/fuchsia/754

用文本編輯器打開~/fuchsia/tools/devshell/lib/fvm.sh，将

stat_output=$(stat "${stat_flags[@]}" "${fvmraw}") 改為

stat_output=$(LC_ALL=C stat "${stat_flags[@]}" "${fvmraw}")

這是似乎是因為系統語言導緻的相關問題。在

size="${BASH_REMATCH[1]}" 的後面下一行

echo $size

====

遇到問題二(權限問題):

ERROR: 'git clone --no-checkout https://chromium.googlesource.com/catapult /home/fuchsia/third_party/catapult' failed:

stdout:

stderr:

正克隆到 '/home/fuchsia/third_party/catapult'...

fatal: 遠端錯誤：

Invalid authentication credentials.

Please generate a new identifier:

  https://chromium.googlesource.com/new-password

問題分解:單獨執行git clone指令仍同樣提示。

問題解決:注冊一下,并把對應的結果在shell中執行一下;

====

遇到問題一(git工具版本号問題):

$ curl -s "https://fuchsia.googlesource.com/fuchsia/+/master/scripts/bootstrap?format=TEXT" | base64 --decode | bash

單獨執行依然報錯 $git init /home/fuchsia

解決方案(git版本号問題),參考連結 https://unix.stackexchange.com/questions/33617/how-can-i-update-to-a-newer-version-of-git-using-apt-get

sudo apt-get install python-software-properties

sudo apt-get install software-properties-common

sudo add-apt-repository ppa:git-core/ppa -y

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install git -y

git --version
