Cmake:ld无法打开映射文件Unit_Test.map:没有这样的文件或目录

我正在Eclipse中进行一个嵌入式C项目，交叉编译到M4 Cortex目标。我们使用Cmake（版本3.7.x）递归所有项目文件，并相应地构建它们。我们有“主应用程序”和“单元测试”。单元测试依赖于“Main_App”中的多个库和源文件。当我构建“单元测试”时，链接器抱怨说它找不到“unit_test.map”

“Cmake:ld无法打开映射文件Unit_Test.map:没有这样的文件或目录”

我的CMakeLists.txt文件如下所示：

cmake_minimum_required(VERSION 3.0.0)

file(GLOB LD_FILE *gcc_nrf52.ld)

create_application(
    NAME
        "Unit_Test"
PLATFORM
        target
INCLUDE_DIRS
    inc
        ../../../apps/Main_App
        ../../../apps/Main_App/stuff
        ../../../apps/Main_App/more_stuff
LINKER_SCRIPT
    ${LD_FILE}
SOURCES
    main.c
LIBRARIES
    someLib1
    someLib2
    someLib3
)

1） 为什么没有创建地图文件？ 2） 我的CMakeLists.txt文件是否不正确？ 3） “Unit_Test”目录中还有什么我遗漏的吗

在我的例子中，我必须添加

\“\”

。CMake不会自动将

“

添加到您的路径中。如果您的路径（在我的情况下）包含任何空格，则需要相应地添加带有

“

的转义序列。那是给你的

"${CMAKE_EXE_LINKER_FLAGS} -Wl,-Map=\"${PROJECT_BINARY_DIR}/${PROJECT_NAME}.map\""

---

它并不是说它找不到

Unit\u Test.map

。它想要写入映射文件，但显然无法写入，因为它被告知写入映射文件的目录不存在。要解释链接命令的错误，您需要向我们展示链接命令及其后续输出，您可以通过运行

make VERBOSE=

而不是

make

获得这些输出。单独编写的

CMakeLists.txt

没有用处。@MikeKinghan，我将发布生成控制台输出以供进一步分析。我不确定Cmake希望我明确说明.map和.hex文件需要放在哪里。在这个构建中，成功创建了一个主应用程序和一个ble应用程序，我找不到该命令存在的位置，无法写入它们各自的.map和.hex文件。在前面的注释中键入：应该是

make VERBOSE=1

该命令的输出是什么

ls/Users/sami/dev/Github/target\u debug\u eclipse\u文件/apps/stim\u module\u unit\u test

@MikeKinghan the the/Users/sami/dev/Github/target_debug_eclipse_files/apps/unit_测试的输出是：“CMakeFiles”、“Makefile”、“cmake_install.cmake”和“promotion_module”。“刺激”模块的“ls”生成：“CMakeFiles”、“Makefile”和“cmake_install.cmake”。
