CMake AMRCC +定制链接器 [英] CMake AMRCC + custom linker

问题描述

我试图在使用 armcc 编译的项目中使用 cmake ，但使用自定义链接器（不是 armlink ）。

I'm trying to use cmake in a project which is compiled using armcc, but use a custom proprietary linker (not armlink).

toolchain.cmake 档案如下：

unset (CMAKE_LINKER CACHE)
set (CMAKE_LINKER "my_linker" CACHE STRING "" FORCE)

unset (CMAKE_ARMCC_LINKER CACHE)
set (CMAKE_ARMCC_LINKER "my_linker" CACHE STRING "" FORCE)

unset (CMAKE_EXE_LINKER_FLAGS CACHE )
set (CMAKE_EXE_LINKER_FLAGS "-flag1 -flag2" CACHE STRING "" FORCE)

unset (CMAKE_C_LINK_EXECUTABLE)
set (CMAKE_C_LINK_EXECUTABLE "<CMAKE_LINKER> <CMAKE_EXE_LINKER_FLAGS> <OBJECTS> <LINK_LIBRARIES> -o <TARGET>")

unset (CMAKE_CXX_LINK_EXECUTABLE)
set (CMAKE_CXX_LINK_EXECUTABLE "<CMAKE_LINKER> <CMAKE_EXE_LINKER_FLAGS> <OBJECTS> <LINK_LIBRARIES> -o <TARGET>")

> cmake 尝试检查我的编译器套件，它在链接步骤失败：

But when cmake tries to check my compiler suite, it fails in the linking step:

-- Check for working C compiler: armcc.exe -- broken
CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.6/Modules/CMakeTestCCompiler.cmake:61 (message):
  The C compiler "armcc.exe" is not able to compile a simple test program.

... (compiling commands that worked hidden here)

Linking C executable cmTC_c08ef.elf

"C:\Program Files (x86)\CMake\bin\cmake.exe" -E cmake_link_script CMakeFiles\cmTC_c08ef.dir\link.txt --verbose=1

my_linker -flag1 -flag2 CMakeFiles/cmTC_c08ef.dir/testCCompiler.o -o cmTC_c08ef.elf --list cmTC_c08ef.map

问题是 - 列出cmTC_c08ef.map 在命令行结尾处（ toolchain.cmake 文件中不存在）。

The problem is the --list cmTC_c08ef.map at the end of command line (which does not exist in the toolchain.cmake file).

为了使其工作，我需要更改文件< cmake_install_dir> \Modules\Compiler\ARMCC.cmake 如下：

In order to make it work, I need to change the file <cmake_install_dir>\Modules\Compiler\ARMCC.cmake as following:

  set(CMAKE_${lang}_LINK_EXECUTABLE      "<CMAKE_LINKER> <CMAKE_${lang}_LINK_FLAGS> <LINK_FLAGS> <LINK_LIBRARIES> <OBJECTS> -o <TARGET> --list <TARGET_BASE>.map")
#  set(CMAKE_${lang}_LINK_EXECUTABLE      "<CMAKE_LINKER> <CMAKE_${lang}_LINK_FLAGS> <LINK_FLAGS> <LINK_LIBRARIES> <OBJECTS> -o <TARGET>")

有一个更好的方法来解决这个问题，只有方式吗？

There is a better approach to solve this issue or it is the only way?

编辑：显然这是在cmake的armcc支持中的一个错误，所以我会保留我的更改在ARMCC.cmake文件。

Apparently this is a bug in the cmake's armcc support, so I will keep my change in the ARMCC.cmake file.

推荐答案

显然，这是在CMake的的支持器armcc的错误，所以我会继续我的ARMCC.cmake文件更改。

Apparently this is a bug in the cmake's armcc support, so I will keep my change in the ARMCC.cmake file.
