Compiling the RISC-V GNU Compiler Toolchain on OS X

[Coderitter GmbH]

Hello everyone,

i want the RISC-V GNU Compiler Toolchain to work on OS X. Here are my steps so far and what goes wrong.

Code:

brew install gawk gnu-sed gmp mpfr libmpc isl zlib

Code:

git clone --recursive https://github.com/pulp-platform/pulp-riscv-gnu-toolchain

Code:

./configure --prefix=/opt/riscv --with-arch=rv32imfdc --with-cmodel=medlow --enable-multilib make

Then i created a disk image of 8 GiB with a case sensitive APFS file system and copied all the files into that disk image. Inside that disk image i run make.

Code:

make

Make returns the following error message which is the same error message if i do not run make inside the disk image.

Code:
