鴻蒙系統(tǒng)移植操作步驟指引---樹(shù)莓派交叉編譯工具鏈配置篇,
本帖最后由 死龍 于 2020-11-13 17:40 編輯
很多朋友對(duì)移植鴻蒙存在不少疑惑,其中對(duì)交叉編譯工具鏈的配置也完全不清楚。 現(xiàn)在我們來(lái)一步步完成樹(shù)莓派3上鴻蒙系統(tǒng)的交叉編譯工具鏈配置操作。
首先,我們?cè)诿钚兄休斎?
復(fù)制代碼 結(jié)果肯定是失敗的,我們來(lái)看看提示。如下圖所示,提示的內(nèi)容是找不到 build/lite/product/rpi3.json 這個(gè)文件。 這么說(shuō)來(lái),編譯腳本第一步就是先定位這個(gè) product 文件夾里的設(shè)置內(nèi)容,然后根據(jù)該文件的設(shè)置布置編譯任務(wù)。

那我們配置的第一步,就是新建這個(gè)文件了
--------------------------------------------------------------------------------------
1、新建 build/lite/product/rpi3.json ,并復(fù)制3518的內(nèi)容
我們?cè)谶@個(gè)文件夾新建 build/lite/product/ rpi3.json 文件,并輸入以下內(nèi)容。

復(fù)制代碼 說(shuō)明:板子設(shè)定為rpi3,編譯器設(shè)定為 arm-none-eabi-gcc,并刪掉一些組件
=========
接下來(lái),我們?cè)龠\(yùn)行一下編譯命令( python build.py rpi3 )。我們填寫(xiě)了一個(gè)不在原系統(tǒng)里支持的編譯器,運(yùn)行命令也是會(huì)出錯(cuò)的。果然,提示不支持這個(gè)編譯器。

好的,那第二步的工作就確定了
--------------------------------------------------------------------------------------
2、 編寫(xiě) arm-none-eabi-gcc 配置文件 我們先用VScode搜索一下 Error: Unsupport compiler 這個(gè)錯(cuò)誤。然后定位到 build/lite/config.py 這個(gè)文件的124行附件。將內(nèi)容修改為以下內(nèi)容 。
- if compiler == “clang“:
- compiler_bin = “clang“
- elif compiler == “arm-none-eabi-gcc“:
- compiler_bin = “arm-none-eabi-gcc“
- elif compiler == “gcc“:
- compiler_bin = “riscv32-unknown-elf-gcc“
- else:
-
復(fù)制代碼 新增了編譯器設(shè)置為 arm-none-eabi-gcc 的判斷和執(zhí)行部分
=======
然后我們?cè)俅?運(yùn)行編譯命令 ,又出現(xiàn)了一個(gè)新錯(cuò)誤提示,如下圖。

好的,這次我們?cè)赩Scode中搜索 not OHOS compiler , 同樣是在 build/lite/config.py 這個(gè)文件的 160行附近找到了對(duì)應(yīng)判斷語(yǔ)句。
我們來(lái)將對(duì)應(yīng)內(nèi)容修改為
- if compiler == \“gcc\“ or compiler == \“arm-none-eabi-gcc\“:
- return True
復(fù)制代碼 ======
然后我們?cè)俅?運(yùn)行編譯命令 ,又出現(xiàn)了一個(gè)新錯(cuò)誤提示,如下圖。

是的,到這一步的時(shí)候,提示就有點(diǎn)奇怪了。明明設(shè)置了 arm-none-eabi-gcc ,卻依然提示找 linux_x86_64_clang 。還是老方法,VScode搜索,找到了 build/lite/config/BUILDCONFIG.gn 的 28 行 ,將內(nèi)容修改為:
- if(ohos_kernel_type == “l(fā)iteos_a“) {
- if(target_cpu == “cortex-a8“) {

- }
- default_target_configs = [ “//build/lite/config:liteos_a“ ]
復(fù)制代碼
同時(shí),build/lite/toolchain/BUILD.gn
文件中似乎也缺少定義,在文件最后添加以下內(nèi)容
- if (ohos_build_compiler == “arm-none-eabi-gcc“) {
- arm_none_eabi_gcc_toolchain(“l(fā)inux_arm_none_eabi_gcc“) {

好的,到這里,基本上就配置得差不多了,我們看一下 out/rpi3/toolchain.ninja
這個(gè)文件,如下圖,gn 工具已經(jīng)正確識(shí)別了工具鏈了

這時(shí)候大家可以再仔細(xì)檢查一下,編譯命令是否正確,不正確的話就回去修改 build/lite/toolchain/arm-none-eabi-gcc.gni
文件。
===========
樹(shù)莓派編譯工具鏈移植暫時(shí)就在這里停止先,還未完成 |
