Build problem in LLVM

[mhomidi]

Hi all,

I have a problem in building LLVM with these parameter.

cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;libunwind" -DLLVM_ABI_BREAKING_CHECKS=FORCE_OFF -DLLVM_INCLUDE_EXAMPLES=OFF -DLLVM_INCLUDE_TESTS=OFF -DBUILD_SHARED_LIBS=True -DCMAKE_INSTALL_PREFIX=$LLVM_PREFIX -DLLVM_BUILD_TESTS=False -DDEFAULT_SYSROOT=$RISCV_TOOLCHAIN_PATH/riscv32-unknown-elf -DLLVM_DEFAULT_TARGET_TRIPLE="riscv32-unknown-elf" -DLLVM_TARGETS_TO_BUILD="RISCV" ../llvm

riscv-toolchain-path is build by this project.

The problem that I face during build process is that it can not link library lib/libLLVMObject.so. The error log is:

[0/5] Performing configure step for 'runtimes'

I do not have any idea about the problem and how solve this because everything seems to be ok. Is there anybody who has an idea how I can solve this issue?
