我正在尝试将 gcc 编译器从版本 8.3 升级到 8.4。官方 gcc 文档建议从源方法编译，平均需要 5 小时。我需要 gcc-8.4 版本来使用 CMAKE 构建一些项目组件。我尝试从位于和y中的同一路径的x （我从源代码编译 gcc-8.4）复制二进制文件，但 cmake 产生以下错误 /usr/local/bin/usr/local/bin
pi@raspberrypi:~/vingman/loki/bld $ cmake -DUNIT_TESTS=OFF -DPLATFORM=RASPI ../

CMake Error at /usr/share/cmake-3.13/Modules/CMakeTestCXXCompiler.cmake:45 (message):
The C++ compiler
"/usr/local/bin/c++"
is not able to compile a simple test program.
It fails with the following output:

但是，当我检查gcc --versiony时，它显示版本 8.4
pi@raspberrypi:~/vingman/loki/bld $ gcc --version
