CMake C 编译器识别失败

Question

最近将 CMake 从 2.8.1 更新到 3.7.1 版，运行良好。

更新需要删除已弃用的 CMAKE_FORCE_C_COMPILER工具链文件中的命令，该文件用于跳过对工作编译器的自动检查。

我试图设置变量，SET(CMAKE_TRY_COMPILE_TARGET_TYPE STATIC_LIBRARY)跳过测试，但行为没有变化。

现在似乎需要检查，CMake 无法识别我的编译器 (TriCore_v6.0r1)。

错误信息:

The C compiler identification could not be found in "C:/Build/CMakeFiles/3.7.1/CompilerIdC/CMakeCCompilerId.elf"

The C compiler identification could not be found in "C:/Build/CMakeFiles/3.7.1/CompilerIdC/CMakeCCompilerId.map"

The C compiler identification could not be found in "C:/Build/CMakeFiles/3.7.1/CompilerIdC/CMakeCCompilerId.mdf"

The C compiler identification could not be found in "C:/Build/CMakeFiles/3.7.1/CompilerIdC/CMakeCCompilerId.o"

Compiling the C compiler identification source file "CMakeCCompilerId.c" failed. Compiler: C:/TASKING/TriCore_v6.0r1/ctc/bin/cctc.exe Build flags: Id flags: -Aa

注意:根据用法，编译器不接受这个标志(-Aa)

The output was:

Checking whether the C compiler is IAR using "" did not match "IAR .+ Compiler":

理想情况下，我希望编译器能够被识别，但由于 Altium 不支持 CMake 工具，如果它解决了我的问题并允许我再次成功构建，我将决定跳过这些检查。

感谢所有回复的人!
正如@Florian 所建议的，可以通过设置变量来强制编译器

SET(CMAKE_C_COMPILER_WORKS TRUE CACHE INTERNAL "")
SET(CMAKE_CXX_COMPILER_WORKS TRUE CACHE INTERNAL "")

但是，我也注意到上面的变量是未设置 没有以下内容:

SET(CMAKE_C_COMPILER_FORCED TRUE CACHE INTERNAL "")
SET(CMAKE_CXX_COMPILER_FORCED TRUE CACHE INTERNAL "")

最后，需要设置另一对变量以防止尝试识别编译器:

SET(CMAKE_C_COMPILER_ID_RUN TRUE CACHE INTERNAL "")
SET(CMAKE_CXX_COMPILER_ID_RUN TRUE CACHE INTERNAL "")

但是，应该注意 Brad King 的评论 in this ticket :

Those toolchain files are setting internal CMake variables like

set(CMAKE_C_COMPILER_ID_RUN TRUE)
set(CMAKE_C_COMPILER_FORCED TRUE)
set(CMAKE_C_COMPILER_WORKS TRUE)

That is not supported because it causes CMake to skip its internal checks that are used to populate other internal settings. Any toolchain file that does that is taking responsibility for updating to set other internal variables as they are added.
