extension `zicsr' required

[ahmdotm]

I used --with-arch=rv64imac_zicsr --with-abi=lp64 for my toolchain configuration and I still get this:
ized opcode csrr a6,mcycleh', extension zicsr' required
make: *** [/home/othman/Reev_EH1/Cores-VeeR-EH1/tools/Makefile:182: printf.o] Error 1

I don't know if it's accurate but a similar issue happened to me.

I used gcc in https://github.com/riscv-collab/riscv-gnu-toolchain and changed the prefix to /opt/riscv/bin/riscv64-unknown-linux-gnu
Then I got Error: unrecognized opcode csrw 0x7c0,x1, extension zicsr required

I didn't succeed in adding ziscr to the default Makefile. It didn't make sense to simply say ABI = -mabi=ilp32 -march=rv32imc_zicsr, because I got /opt/riscv/lib/gcc/riscv64-unknown-linux-gnu/14.2.0/../../../../riscv64-unknown-linux-gnu/bin/ld: /opt/riscv/lib/gcc/riscv64-unknown-linux-gnu/14.2.0/../../../../riscv64-unknown-linux-gnu/lib/libgcc_s.so.1: error adding symbols: file in wrong format'

Merry Christmas to you all btw.

I have fixed my issue by rebuilding the toolchain and using --with-arch=rv32imc_zicsr --with-abi=ilp32.

Can't thank you enough for this, besides make sure to modify tools/Makefile

1. L23: ABI = -mabi=ilp32 -march=rv32imc_zicsr
2. L77: CFLAGS += "-std=c++17"
