Thanks, Siwei for the info. I'll give it a try.
Running seL4 no longer requires RISC-V tools. In case you want to use Spike, I'd suggest building the riscv-isa-sim separately to get the latest code.
Does this require RISC-V tools to build? Best, Jacob On Sun, Nov 10, 2019 at 10:58 PM Zhuang, Siwei (Data61, Kensington NSW) < Siwei.Zhuang@data61.csiro.au> wrote:
Hi Jacob,
You need to enable multilib when building "riscv-gnu-toolchain".
./configure --prefix=/path-to-install-toolchain --enable-multilib then make or make linux

Hi
I am trying to build "seL4 tests" for "Spike" platform (the RISC-V simulator from UC Berkeley) on Ubuntu 18.04.3 LTS, a 64-bit system.
First of all, I was able to build RISC-V tools with "build.sh" after manually installing "riscv-gnu-toolchain" from GitHub as well as additional python modules (future, ply, protobuf). I then kicked of "../init-build.sh -DPLATFORM=spike -DRISCV64=TRUE -DSIMULATION=1" from local build

After that, however, "ninja" command complained about "undefined

to `__nedf2'". I understand there is no FPU support in "Spike" platform so a need for "soft-float" module. Where should I specify "-lsoft-fp"?
Any suggestions?
Thanks,
