<pre>
    When build llvm12, I got a build error in centos7 with gcc7.3.


Here is my cmake option
cmake -G "Unix Makefiles"                                          \
                 -DCMAKE_INSTALL_PREFIX=$INSTALL       \
                 -DCMAKE_BUILD_TYPE=Release                 \
                 -DLLVM_OPTIMIZED_TABLEGEN=On          \
                 -DLLVM_USE_LINKER=gold      
                 -DLLVM_ENABLE_PROJECTS=clang;compiler-rt;lld;clang-tools-extra      \
                 -DLLVM_LINK_LLVM_DYLIB=On                   \
                 -DLLVM_ENABLE_ZLIB=OFF                         \
                 -DLLVM_ENABLE_TERMINFO=OFF               \
                 -DLLVM_TARGETS_TO_BUILD="X86;RISCV" 

it works in ubuntu.

What can I do to solve it?
