problem with installing spike simulator.

[nandeesh v]

Hello,

I'm facing problem with installing spike simulator. Below is what I am doing.

Since we only need to build a few tools, we will use a modified build script, listed in its entirety below. Remember that we'll build riscv64-unknown-linux-gnu-gcc shortly afterwards. If you want to build the full toolchain for later use, see here.

[build-spike-only.sh contents]
1 #!/bin/bash
2 . build.common
3 build_project riscv-fesvr --prefix=$RISCV
4 build_project riscv-isa-sim --prefix=$RISCV --with-fesvr=$RISCV

Run the build script.

$ ./build-spike-only.sh
 

When i run this script I get an error as below

"Please set the RISCV environment variable to your preferred install path."  (This is from bulid.common)

But I clearly set my RISCV variable to install path "/home/nandeesh/lowrisc-chip/fpga-zynq/rocket-chip/riscv-tools/riscv-gnu-toolchain-compiled". Please help me in resolving this issue. 

riscv64-unknown-elf-gcc  and riscv64-unknown-linux-gnu-gcc are woring fine.
