Version v7.2.0-3-20180506 is a maintenance release of GNU MCU Eclipse
RISC-V Embedded GCC; it updates to the latest RISC-V sources and the
build process was improved, to add
gdb-py and to support even older
GNU/Linux machines and processors.
By the date of this release, the
riscv-gcc-7.3.0 branch is not yet
stable, thus the current version is still based on GCC 7.2, using the
- the riscv/riscv-gcc project,
riscv-gcc-7.2.0, commit 36e932c from from Jan 16th, 2018
- the riscv/riscv-binutils-gdb
riscv-binutils-2.29, commit f60a065 from May 3rd, 2018
- the riscv/riscv-newlib project, commit 1e50b13 from Feb 27th, 2018
All architectures, ABIs and libraries supported by the
toolchain are also supported, with the following improvements:
- a newer
newlibwas included, which supports the ‘underscore’ syscall functions
- the mandatory reference to
libglossin the linker configuration was removed
march=rv32imaf/mabi=ilp32flibrary was added to the list of multilibs
- support for
- the standard documentation, in PDF and HTML, was added
Binaries for Windows, macOS and GNU/Linux are provided.
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.
- due to a missing option in the build script, the libraries are not functional for 64-bit devices, the build fails (fixed in 7.2.0-4):
locale.c:(.text.__locale_ctype_ptr+0x8): relocation truncated to fit: R_RISCV_HI20 against `.LANCHOR0'
libnosyslibrary does not export the correct underscore symbols.
The SHA-256 hashes for the files are:
