Question

我将CMake与QNX Momentics一起使用。为此，我执行了命令

cmake -DCMAKE_TOOLCHAIN_FILE=/my-path/qnx.cmake

在终端上显示了以下提到的错误：

ERROR:-
"-- The C compiler identification is unknown
CMake Error at CMakeLists.txt:7 (project):
  The CMAKE_C_COMPILER:
    /home/mobis/MTCI/Test/host/linux/x86_64/usr/bin/ntox86_64-gcc
  is not a full path to an existing compiler tool.
  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH."

我已经在本地计算机中检查了ntox86_64-gcc编译器，并且该编译器位于/hom/Test/host/linux/x86_64/usr/bin位置。
我试图通过使用CMake在命令行中提供编译器路径来进行构建，但它显示出相同的错误。
即使遇到相同的错误，也尝试过以下解决方案：

CMAKE_C_COMPILER is not a full path to an existing compiler tool
```
export CC=/usr/bin/gcc
export CXX=/usr/bin/g++
```

请在我的 qnx.cmake 下找到：

set(CMAKE_SYSTEM_NAME QNX)
set(CMAKE_HOST_SYSTEM_NAME QNX)
set(CMAKE_SYSTEM_VERSION 7.0.0)
set(arch ntox86_64)
set(QNX_PROCESSOR x86_64)
SET( TOOLCHAIN QNX )

#Check environment variables
if ("$ENV{QNX_HOST}" STREQUAL "")
    message(FATAL_ERROR "QNX_HOST environment variable not set")
endif()

if ("$ENV{QNX_TARGET}" STREQUAL "")
    message(FATAL_ERROR "QNX_TARGET environment variable not set")
endif()

set(QNX_HOST "$ENV{QNX_HOST}")
set(QNX_TARGET "$ENV{QNX_TARGET}")
set(CMAKE_C_COMPILER "${QNX_HOST}/usr/bin/${arch}-gcc")
set(CMAKE_CXX_COMPILER "${QNX_HOST}/usr/bin/nto${QCC_NTOARCH}-g++")


set(CMAKE_C_FLAGS_DEBUG "-g")
set(CMAKE_C_FLAGS_MINSIZEREL "-Os -DNDEBUG")
set(CMAKE_C_FLAGS_RELEASE "-O3 -DNDEBUG")
set(CMAKE_C_FLAGS_RELWITHDEBINFO "-O2 -g")
set(CMAKE_CXX_FLAGS_DEBUG "-g -D_DEBUG")
set(CMAKE_CXX_FLAGS_MINSIZEREL "-Os -DNDEBUG")
set(CMAKE_CXX_FLAGS_RELEASE "-O3 -DNDEBUG")
set(CMAKE_CXX_FLAGS_RELWITHDEBINFO "-O2 -g")

set(CMAKE_FIND_ROOT_PATH "${QNX_TARGET}")
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

请在我的 CMakeLists.txt 下找到：

cmake_minimum_required(VERSION 3.14.2)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(CMAKE_BUILD_TYPE Release)
project(Test VERSION 1.0     DESCRIPTION "CoreLSP FOlder structure     project"   LANGUAGES C)
set(SRCS 
   main.c
   printing.c
   ) 
add_executable(Test ${SRCS})

预期：

应该成功构建项目并生成makefile，以便可以将项目导入QNX Momentics IDE（基于Linux的主机OS）。

使用qnx.cmake会显示错误“ CMAKE_C_COMPILER不是现有编译器工具的完整路径。”
