To build for RISC-V you only need binutils + gcc (riscv64). The errors you get when running `newt test ...` are because the tests run on a simulated environment. You need gcc-multilib and a 32-bit libc-dev. Not sure which distro you use, but installing `libc6-dev`on a 64-bit distr installs only the 64-bit libc. To get 32-bit, for Ubuntu you would need to install like this: `apt-get install linux-libc-dev:i386 `. Or just search with your package manager for something like "libc-dev-i386".
Re: Setting up RISC-V toolchain for Linux
Should be in place. Possibly some problems with glibc for riscv64 installation. On 08.11.2018 1:04, PEIJIE LI wrote: Hi Andrey: Thank you for your help. I switched to use the risvc64 package.

Re: Setting up RISC-V toolchain for Linux
Hi Andrey: Thank you for your help. I switched to use the risvc64 package. Yet I am still seeing the missing sys/mman.h error. I tried installing gcc-multilib, build-essential, libc6-dev but none of them solves the problem. Any idea on what I should do to fix this? Thanks!

Re: Setting up RISC-V toolchain for Linux
There is riscv64 package in compiler folder. Why not to try it? Just change 'bsp.compiler' value in your bsp.yml.

Setting up RISC-V toolchain for Linux
Hi, I am trying to set up RISC-V as the toolchain on a Linux system. But I am getting an error saying "sys/mman.h: No such file or director”. Here is what I did: 1. I installed newt by following the instructions on “Installing Newt on Linux” 2. I then modified the /repos/apache-mynewt-core/compiler/sim/compiler.yml file to change the default gcc-5 to riscv64-unknown-elf-gcc. 3. I ran newt test @apache-mynewt-core/sys/config The full error message is hw/bsp/native/src/sbrk.c:20:10: fatal error: sys/mman.h: No such file or directory #include ^~~~ compilation terminated. Error: Test failure(s): Passed tests: [] Failed tests: [sys/config/test-fcb sys/config/test-nffs] And all tests passed before I changed the compiler.yml file. The error messages is saying there is a missing file, but I don’t really know how I can fix it. I don’t have much experience in doing this, so any advice will be helpful! Thank you very much! Best, Peijie
