我有一个使用qemu模拟运行的riscv64 linux(fedora 28)。

[gqb@stage4 cpu2006]$ uname -a

Linux stage4.fedoraproject.org 4.19.0-rc8 #1 SMP Wed Oct 17 15:11:25 UTC 2018 riscv64 riscv64 riscv64 GNU/Linux

我的gcc版本是7.3.1 20180303 (Red Hat 7.3.1-5) (GCC) 。

我已经成功构建了工具并安装了它(执行./install.sh )。

[gqb@stage4 cpu2006]$ ./install.sh

SPEC CPU2006 Installation

Top of the CPU2006 tree is '/home/gqb/cpu2006'

There appears to be only one valid toolset:

riscv64-linux

Use this? (y/n)

y

Top of SPEC benchmark tree is '/home/gqb/cpu2006'

Everything looks okay. cd to /home/gqb/cpu2006,

source the shrc file and have at it!

我从这里获取了cfg文件，并进行了以下更改：

- CC = riscv64-unknown-linux-gnu-gcc -static -Wl,-Ttext-segment,0x10000

- CXX = riscv64-unknown-linux-gnu-g++ -static -Wl,-Ttext-segment,0x10000

- FC = riscv64-unknown-linux-gnu-gfortran -static -Wl,-Ttext-segment,0x10000

+ CC = gcc -static

+ CXX = g++ -static

+ FC = gfortran -static

但是，当我尝试运行runspec --config riscv.cfg --noreportable 482.sphinx3进行测试时，出现错误：

[gqb@stage4 cpu2006]$ runspec --config riscv.cfg --noreportable 482.sphinx3

我以前见过这个问题 ，但似乎无法解决我的问题。

我该如何解决？

谢谢！
