Linux toolchain build failure #8

Closed arunthomas closed 9 years ago

arunthomas commented 9 years ago

I am having issues building the Linux riscv-isa-toolchain on Ubuntu 14.04. Here's the error I'm seeing during the glibc build:

I think you don't have the install prefix in your PATH? On Nov 25, 2014 2:17 PM, "Arun Thomas" notifications@github.com wrote:

Thanks for the response. /opt/riscv/bin is in my PATH.

I ran ./configure --prefix=/opt/riscv.

palmer-dabbelt commented 9 years ago

I have only gotten this error when glibc's autoconf detects you don't have "riscv64-unknown-linux-gnu-gcc" and tries to just use "gcc", which targets x86 and there for doesn't understand RISCV assembly.

You should be able to check your build log for libc and check if it's using your system GCC. If so then I'd recommend cleaning everything and rebuilding with that PATH set first.

If that's not it then I'm afraid I'm out of ideas... On Nov 25, 2014 2:28 PM, "Arun Thomas" notifications@github.com wrote:

Based on the build output, it is falling back to the system gcc.

The strange thing is that the PATH is set correctly:

arun@yoshi:~$ which riscv64-unknown-linux-gnu-gcc
/opt/riscv/bin/riscv64-unknown-linux-gnu-gcc

I just did a clean build, and I got the same error.

Try:

CC=riscv-gcc ./configure --prefix=/opt/riscv

This was user error on my part. I was building with sudo, and the PATH wasn't getting set correctly as Palmer suggested. Sorry for the noise, and thanks for the help.
