使用 CMake 生成的 makefile 构建 PIC32 项目失败

Question

我正在尝试为 PIC32 设置 CMake 项目。这是我第一次建立 CMake 项目。只有一个带有空

main 

函数的源文件。没有额外的库。链接器脚本取自 MPLABX 项目。

我的 CMakeLists.txt 文件与此 PIC32-Project-Template 类似。下面是我的 CMakeLists.txt

cmake_minimum_required(VERSION 3.27.4 FATAL_ERROR)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

# Tell CMake that we are cross compiling
set(CMAKE_SYSTEM_NAME Generic)
set(CMAKE_SYSTEM_PROCESSOR mips)
set(CMAKE_CROSSCOMPILING 1)
# Generate commands in compile_commands.json without acutally building the sources
set(CMAKE_EXPORT_COMPILE_COMMANDS ON)
# Enable verbose output for 'make' command
set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_RULE_MESSAGES OFF)

# Set device family pack (specific to microchip)
set(DFP C:/Program\ Files/Microchip/MPLABX/v6.00/packs/Microchip/PIC32MZ-EF_DFP/1.3.58)

# Set device
set(DEVICE 32MZ2048EFM100)

# Set compiler
set(COMPILER_PATH C:/Program\ Files/Microchip/xc32/v4.00/bin)
set(CMAKE_C_COMPILER ${COMPILER_PATH}/xc32-gcc.exe CACHE PATH "" FORCE)
set(CMAKE_CXX_COMPILER ${COMPILER_PATH}/xc32-g++.exe CACHE PATH "" FORCE)

set(SOURCES main.cpp)

project(BuildSetup LANGUAGES CXX)

add_executable(${PROJECT_NAME}.elf ${SOURCES})

add_custom_command(
   OUTPUT  ${PROJECT_NAME}.hex
   DEPENDS ${PROJECT_NAME}.elf
   COMMAND C:/Program\ Files/Microchip/xc32/v4.00/bin/xc32-bin2hex.exe ${PROJECT_NAME}.elf
)

add_custom_target(${PROJECT_NAME}_hex ALL
   DEPENDS ${PROJECT_NAME}.hex)

target_compile_definitions(${PROJECT_NAME}.elf PUBLIC XPRJ_curiosity_debug=curiosity_debug)

# Set linker options and flags
target_link_options(${PROJECT_NAME}.elf PUBLIC -mprocessor=${DEVICE} -O0)

target_link_libraries(${PROJECT_NAME}.elf "-Wl,--defsym=__MPLAB_BUILD=1,--script=\"p32MZ2048EFM100.ld\",--defsym=_min_heap_size=65536,--no-code-in-dinit,--no-dinit-in-serial-mem,-Map=\"${PROJECT_NAME}.map\",--report-mem,--cref,--memorysummary,memoryfile.xml")

下面的 CMake 命令成功在

build 

目录中生成所需的 makefile。

cmake.exe -G "MinGW Makefiles" -D"CMAKE_MAKE_PROGRAM:PATH=C:\Program Files\Microchip\MPLABX\v6.00\gnuBins\GnuWin32\bin\make.exe" -B ./build

使用

make --no-print-directory

目录中的

build 

命令构建失败，并出现以下错误。如何成功构建项目？

xc32_device.info

的默认位置是

C:\Program Files\Microchip\MPLABX\v6.00\packs\Microchip\PIC32MZ-EF_DFP\1.3.58\xc32\ 

。该文件和

32MZ2048EFM100 

文件夹的内容按照标准安装，没有修改。 最初，我认为该错误可能与

xc32 

或其子文件夹的访问限制有关。我向当前用户提供了所有读写修改权限，并尝试使用管理员权限执行

make 

命令，但徒劳无功。

Answer 1

我的错。在访问 CMakeLists.txt 文件中的变量之前，我错过了

$

符号。
