根因分析

通过 -DCMAKE_TOOLCHAIN_FILE 指定的路径不存在、不是文件或包含语法错误。

English

The path specified via -DCMAKE_TOOLCHAIN_FILE does not exist, is not a file, or contains syntax errors.

解决方案

  1. Use absolute path: cmake -DCMAKE_TOOLCHAIN_FILE=/full/path/to/toolchain.cmake /path/to/source
  2. Check file existence: ls -la /path/to/toolchain.cmake and verify it has no syntax errors by running cmake -P /path/to/toolchain.cmake.
  3. Set the toolchain file in a cache variable before project(): set(CMAKE_TOOLCHAIN_FILE "${CMAKE_SOURCE_DIR}/toolchain.cmake" CACHE PATH "")

无效尝试

常见但无效的做法:

  1. 70% 失败

    CMake resolves relative paths from the build directory, not the source directory; leads to 'not found'.

  2. 85% 失败

    Toolchain file must be set before the first project() command; otherwise CMake ignores it.
