The GNU/Linux binaries were built on two CentOS 6 Docker images (32/64-bit), and run on any distribution based on CentOS 6 or later.
The Windows binaries were built with mingw-w64, and run on any reasonably recent i686 and x86_64 Windows machines.
Instructions on how to install the binaries are available in the How to install the RISC-V toolchain? page.
$ xpm install --global @gnu-mcu-eclipse/riscv-none-gcc
This installs the latest available version.
For better control and repeatability, the build scripts use Docker containers; all files required during builds are available as a separate gnu-mcu-eclipse/riscv-none-gcc-build project.
libnosyslibrary does not export the correct underscore symbols.
