TI cl2000 cmake CXX编译器标识未知

Question

我正在尝试使用来自 TI 的 cl2000.exe compiler/linker 进行交叉编译，但我遇到了 CMake compiling/linking 其简单测试程序的问题。

我使用的工具链文件是（从this gist复制）：

set(TI_TOOLCHAIN_DIR "C:/ti/ccs901/ccs/tools/compiler/ti-cgt-c2000_18.12.1.LTS")

set(CMAKE_SYSTEM_NAME Generic)
set(CMAKE_SYSTEM_VERSION 1)

# toolchain paths
find_program(TI_GCC             NAMES   cl2000    PATHS  ${TI_TOOLCHAIN_DIR}/bin    NO_DEFAULT_PATH)
find_program(TI_CXX             NAMES   cl2000    PATHS  ${TI_TOOLCHAIN_DIR}/bin    NO_DEFAULT_PATH)
find_program(TI_AS              NAMES   cl2000    PATHS  ${TI_TOOLCHAIN_DIR}/bin    NO_DEFAULT_PATH)
find_program(TI_AR              NAMES   ar2000    PATHS  ${TI_TOOLCHAIN_DIR}/bin    NO_DEFAULT_PATH)
find_program(TI_OBJCOPY         NAMES   ofd2000   PATHS  ${TI_TOOLCHAIN_DIR}/bin    NO_DEFAULT_PATH)
find_program(TI_OBJDUMP         NAMES   hex2000   PATHS  ${TI_TOOLCHAIN_DIR}/bin    NO_DEFAULT_PATH)
find_program(TI_SIZE            NAMES   size2000  PATHS  ${TI_TOOLCHAIN_DIR}/bin    NO_DEFAULT_PATH)
find_program(TI_LD              NAMES   cl2000    PATHS  ${TI_TOOLCHAIN_DIR}/bin    NO_DEFAULT_PATH)

# set executables settings
set(CMAKE_C_COMPILER    ${TI_GCC})
set(CMAKE_CXX_COMPILER  ${TI_CXX})
set(AS                  ${TI_AS})
set(AR                  ${TI_AR})
set(OBJCOPY             ${TI_OBJCOPY})
set(OBJDUMP             ${TI_OBJDUMP})
set(SIZE                ${TI_SIZE})
set(LD                  ${TI_LD})

它似乎正确地将 C 编译器检测为 TI，而不是 CXX 编译器：

$ cmake -DCMAKE_TOOLCHAIN_FILE=../toolchain-cl2000.cmake -G "Unix Makefiles" ..

  It fails with the following output:

我试过：

set(CMAKE_EXE_LINKER_FLAGS "-z")
- 导致从编译器命令行调用链接器。
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -eo=cxx.obj")
- 这解决了 cl2000.exe 从 .cxx.obj 简单测试程序中删除 .cxx 的问题。

启用 -z 标志只会产生以下错误：

<Linking>
    "C:\Users\user\AppData\Local\Temp\{F59696C9-9FC5-441B-8BA5-AC3022232249}", line 5: error:
       cannot find file "CMakeFiles/cmTC_d4b00.dir/testCXXCompiler.cxx.obj"
    fatal error: no input files

然后添加-eo=cxx.obj选项也产生同样的错误。

有没有人使用 CMake 和 cl2000 成功交叉编译 C/C++？

Answer 1

问题是 cl2000 编译器生成 .obj 文件，其中编译器信息字符串为 UTF-16BE，CMake 假定它们为 UTF-8。 CMake 3.16.0 中计划包含一个修复程序，CMake 现在将为 cl2000 编译器正确检测 C 和 CXX 编译器标识。
