How to publish the RISC-V Embedded GCC binaries?

The RISC-V Embedded GCC binaries are published on GitHub Releases.

Update the Change log

Generally, apart from packing, there should be no local changes.

In the documentation git, add new entries to the Change log (pages/toolchain/riscv/, grouped by days.

Update the CHANGES.txt file

In the gnu-mcu-eclipse/riscv-none-gcc-build project git, edit the gnu-mcu-eclipse/info/CHANGES.txt file (copy the entries from the web change log).

Add tags to source repos

Check the project riscv/riscv-gnu-toolchain, and determine the specific commits used in the official distribution.

Add tags with the original version number (like v20170612), in the following projects:

Update the script

In the gnu-mcu-eclipse/riscv-none-gcc-build, update the scripts/ to refer to the latest version number.

Check if the library sources (gmp, mpfr, mpc, isl) did change and possibly update them.


Follow the steps in the separate How to build page.

Prepare a new blog post to announce the release

In the documentation git:

  • add a new file to _posts/riscv-none-gcc/releases
  • name the file like
  • name the post like: GNU MCU Eclipse RISC-V Embedded GCC v7.1.1-1-20170702-* released.
  • in the Binary files » link, use the Releases URL, like (the page must exist, otherwise publishing will fail)

Update the release post with the SHA hashes

Copy/paste the build report at the end of the post as
