Question

我正在尝试使用CMake构建我的个人项目。但是，这样做时会收到以下错误消息：

$ cmake ../somePath/ -DCMAKE_C_COMPILER='/home/John/Downloads/arduino-1.8.10-linux64/arduino-1.8.10/hardware/tools/avr/bin/avr-gcc-7.3.0'

    "/home/John/Downloads/arduino-1.8.10-linux64/arduino-1.8.10/hardware/tools/avr/bin/avr-gcc-7.3.0"

  is not able to compile a simple test program.

  It fails with the following output:

  CMake will not be able to correctly generate this project.

它抱怨它不知道-rdynamic选项。我发现multiple very old posts telling this is a bug of CMake

当今是否有此修复程序？

这是我的CMakeLists.txt文件：

SET(CMAKE_SYSTEM_NAME Generic)
SET(CMAKE_SYSTEM_PROCESSOR avr)
SET(CMAKE_CROSSCOMPILING 1)
set(CMAKE_TRY_COMPILE_TARGET_TYPE STATIC_LIBRARY)
set(CMAKE_SHARED_LIBRARY_LINK_C_FLAGS "")

cmake_minimum_required(VERSION "3.5")

#overwrite default gcc compiler
set(CMAKE_C_COMPILER "/home/John/Downloads/arduino-1.8.10-linux64/arduino-1.8.10/hardware/tools/avr/bin/avr-gcc-7.3.0")
#overwrite default linker
set(CMAKE_LINKER "/home/John/Downloads/arduino-1.8.10-linux64/arduino-1.8.10/hardware/tools/avr/bin/avr-ld")
SET(CWARN "-Wall -Wstrict-prototypes")
SET(CTUNING "-funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums")

...

add_subdirectory(test)

...
)

CMake-“错误：无法识别的选项'-rdynamic'”
