Subject: [GSoC2016] Weekly Report of Porting musl to RISC-V Project #1
Hello all,
It is the second issue of weekly report of porting musl to RISC-V GSoC project.
I am still working on integrating toolchain and building userland.
On the toolchain side, the WIP branch [1] has been upgraded to recent
upstream using riscv-binutils-gdb.
On the userland side, I have built statically-linked BusyBox as the
first target. BusyBox 1.24.2 can be built using [1] and attached
.config file. Using the Linux kernel 4.1.17 + RISC-V patches [2] built
with a glibc-based toolchain and Spike, a system with the busybox
binary boots up, launches init and finally provides a shell!
(I am using Linux kernel built with a glibc-based toolchain because I
am using GCC6 for integration and Linux 4.1.17 has no support for
that.)
However, the shell can't execute other programs with "permission
denied" errors, while built-in commands works well. I try to figure
out the cause.
The progress is slower than what I expected last week but there is no
delay from the proposed plan. In next week, I will debug the issue
above and work on the libc's arch-dependent part.
Have a nice weekend!
