求助：环境rocky linux9.3，amd 7950x
参考的贴子http://bbs.keinsci.com/thread-40792-1-1.html
which clang、clang++、flang都有路径显示，
编译时也写的绝对路径，如下：
- ./configure CC=/opt/aocc-compiler-4.1.0/bin/clang CXX=/opt/aocc-compiler-4.1.0/bin/clang++ FC=/opt/aocc-compiler-4.1.0/bin/flang --prefix=/opt/openmpi-5.0.0-aocc
但是在编译openmpi-5.0.0和openmpi-4.1.6 时均报错。
错误显示：
*** C++ compiler and preprocessor
checking whether the compiler supports GNU C++... yes
checking whether /opt/aocc-compiler-4.1.0/bin/clang++ accepts -g... yes
checking for /opt/aocc-compiler-4.1.0/bin/clang++ option to enable C++11 features... none needed
checking dependency style of /opt/aocc-compiler-4.1.0/bin/clang++... gcc3
checking how to run the C++ preprocessor... /opt/aocc-compiler-4.1.0/bin/clang++ -E
checking if C and C++ are link compatible... no

请问是什么原因呢，该如何解决？
