使用CMake編譯CH32V10x, CH32V30x(VSCode, Clion優(yōu)雅寫代碼)

MRS?IDE?基于Eclipse,?代碼體驗與同出一處的STM32CubeIDE基本一樣,?相比Keil來說,?體驗好很多了，但是與VScode，?Clion體驗還是差了不少，看了編譯流程，?是使用make，?因此使用Cmake生成Make是沒問題的。


準(zhǔn)備工具：CMake，RISC-V Embedded GCC，make


其中CMake，?make比較好找。在經(jīng)過我試驗之后發(fā)現(xiàn)，?WCH使用的RISC-V編譯器與通用的RISC-V編譯器不太一樣，?有些地方是修改過了，?在使用xpack-riscv-none-elf-gcc-12.1.0-2編譯時 core-riscv.c?文件內(nèi)大量的匯編語言是報錯的,?應(yīng)該使用特有指令。所以只能使用MRS安裝路徑下提供的RISC-V Embedded GCC，?


CMakeLists.txt與使用STM32的時候是差不多的，只需要修改少量地方，?一個是指定編譯器平臺，?一個是編譯參數(shù)和鏈接參數(shù)

具體可以參考以下:

  1. ?設(shè)置Clion工具鏈。

    XSL2022-09-04_14-55-55.png

    環(huán)境腳本內(nèi)容需要修改你自己的路徑：

set?PATH=path\to\your\MounRiver_Studio\toolchain\RISC-V?Embedded?GCC\bin;%PATH%

? ? ? ?選擇工具鏈

XSL2022-09-04_15-02-30.png

? ?接下來就可以編譯了

XSL2022-09-04_15-04-30.png

和MRS編譯相比:

? 2.2.?配置CMake,?主要配置CMake環(huán)境變量,?編譯平臺,?該配置文件需要在工程根目錄下下新建 .vscode 文件夾,?在 .vscode

?文件夾下新建 settings.json?,?內(nèi)容參考如下,?需要根據(jù)實際情況修改:

? ?另外還需配置C/C++插件,?主要是? intelliSenseMode?和?configurationProvider

"configurationProvider":?"ms-vscode.cmake-tools",
"intelliSenseMode":?"gcc-x86"


? ?接下配置CMake,?編譯平臺在CMakeLists.txt里指定了,?路徑環(huán)境變量在?settings.json?里? cmake.environment?指定了。

? ?VSCode底邊欄應(yīng)該是這樣的：

XSL2022-09-04_15-23-32.png


在左邊欄,?點擊Cmake圖標(biāo),?再點擊配置項目

XSL2022-09-04_15-24-41.png


接下來編譯即可,?點擊底邊欄的 Build,?等待完成，?無錯誤的話，?應(yīng)該輸出如下：



XSL2022-09-04_15-28-13.jpg


示例工程:

icon_rar.gifwch_riscv_cmake_template.zip


使用VSCode,?Clion?均無法調(diào)試下載,?OpenOCD是WCH修改編譯過才能識別WLink,?原生OpenOCD是無法識別WLink的,?期待WCH進(jìn)一步開放相關(guān)資料

我使用GCC的C++時，發(fā)現(xiàn)--gc-section似乎是失效的。

add_compile_options(-march=rv32imac_zicsr_zifencei)

add_compile_options(-mabi=ilp32 -mcmodel=medany -msmall-data-limit=8 -mno-save-restore)

add_compile_options(-fmessage-length=0 -fsigned-char -ffunction-sections -fdata-sections -fno-common)

add_compile_options(-ggdb)

add_compile_options(-Os)

add_compile_options(-Wall)


set(LINKER_SCRIPT ?${CMAKE_CURRENT_SOURCE_DIR}/../Code/Ld/bootld.ld)

add_link_options(

? ? -march=rv32imac -mabi=ilp32

? ? -nostartfiles

? ? -Xlinker --gc-sections ?

? ? -Wl,--print-memory-usage

? ? -Wl,-Map,${PROJECT_NAME}.map

? ? --specs=nano.specs

? ? --specs=nosys.specs

? ? )

add_link_options(-T ${LINKER_SCRIPT})

add_link_options(-Wl,-check-sections -Wl,-fatal-warnings -Wl,--gc-sections -Wl,--print-memory-usage)

add_link_options(-nostartfiles -Xlinker --gc-sections)




我嘗試各種方法加上--gc-section，但是編譯出的文件還是包含不用的函數(shù)，在編譯時，刪除不用的函數(shù)會讓HEX體積減小。

我用的是

?set(WIN_TOOLPATH ?C:/Tool/RISC-V_Embedded_GCC12/bin/riscv-none-elf-)

? ? MESSAGE(STATUS "Now is windows!")

? ? set(CMAKE_C_COMPILER ${WIN_TOOLPATH}gcc.exe)

? ? set(CMAKE_CXX_COMPILER ${WIN_TOOLPATH}g++.exe)

? ? set(CMAKE_ASM_COMPILER ${WIN_TOOLPATH}gcc.exe)

? ? set(CMAKE_AR ${WIN_TOOLPATH}ar.exe)

? ? set(CMAKE_OBJCOPY ${WIN_TOOLPATH}objcopy.exe)

? ? set(CMAKE_OBJDUMP ${WIN_TOOLPATH}objdump.exe)

? ? set(SIZE ${WIN_TOOLPATH}size.exe)


不知道這個問題在C語言上是否存在。
