Hi, After I compiled riscv-binutils/riscv-gcc/riscv-newlib, I encountered some errors when I use riscv gcc to compile coremark. Then I add "--with-abi=lp64" in the configure option for these repos. Same errors occur. riscv_binutils configure: ../riscv-binutils/configure --with-abi=lp64 --prefix=/home/syven.wang/local2/gcc-b --target=riscv64-unknown-elf riscv_gcc configure: ../riscv-gcc/configure --with-abi=lp64 --prefix=/home/syven.wang/local2/gcc-b --target=riscv64-unknown-elf --enable-languages=c --disable-libssp riscv-newlib configure: ../riscv-newlib/configure --with-abi=lp64 --prefix=/home/syven.wang/local2/gcc-b --target=riscv64-unknown-elf
