I need to add support for “- lc++, - lc++abi, - lunwind, - lclang_rt.builtins_riscv32” libraries for the Clang compiler, because when I use the clang compiler to compile projects, I am prompted that these libraries cannot be found. So I re download the LLVM 15.04 compressed package in github. After decompression, execute the following command to build:
cd llvm-project-15.04.src
mkdir build
cd build
cmake -G "Unix Makefiles" \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_TARGETS_TO_BUILD="RISCV" \
-DLLVM_ENABLE_PROJECTS="clang;libcxx;libcxxabi;libunwind;compiler-rt" \
../llvm
make -j2
However, an error is reported during execution. The error log is as follows:
