Thanks Maxim,

I think I am using the latest library.

Do you have  /usr/include/features.h  file ?
It should be installed with libc6-dev package.

This means that your gcc configured in some non-standard way. Could you put here an output of:
$ gcc -v

?
But in any case, you can add /usr/include directory to headers search path by setting C_INCLUDE_PATH environment variable:
$ export C_INCLUDE_PATH=/usr/include

Oh, sorry Mathew, I just realized that this error happens inside RISC-V toolchain and it's actually needs not host (x86), but RISC-V headers.
Did you properly set TOP and RISCV environment variables before running build.sh ?

I have used this directory always.

Which version of GCC are you using? I have tried multiple versions(5 and 6) but they were all same.

/var/cache/distfiles/newlib-2.2.0.tar.gz: No such file or directory

=>
I have seen similar error in my environment where network access partially restricted. I just downloaded newlib file from the internet, place it inside distfile folder, than modified makefile to refer to local directory instead of url. Then installation performed fine.

You may try this.

BTW, pleae just summarize the error in the mail thread and if you must, attach file for the full log. I think it is rather hard to read.

Best luck!
Jamie

Hi Jamie and Maxim,

Thanks for your response.
That removed the "newlib-2.2.0.tar.gz" error but not others yet.
I have attached the full log file. Please see the attached file.

There are two types of errors (and the second is what Maxim commented):

/design/rocket/rocket-chip/riscv-tools/riscv-gnu-toolchain/build/src/newlib-gcc/libcpp/macro.c:3093:58: warning: format not a string literal and no format arguments [-Wformat-security]
        cpp_error (pfile, CPP_DL_ERROR, paste_op_error_msg);


/usr/include/x86_64-linux-gnu/sys/types.h:25:22: fatal error: features.h: No such file or directory
 #include <features.h>


Regards,
Matthew

First is a warning, not error. The only issue you have that during riscv toolchain build host headers start to include instead of  riscv headers.
And this is something very weird.
Could you put here a build.log and config.log files located in /design/rocket/rocket-chip/riscv-tools/riscv-gnu-toolchain/build/  and /design/rocket/rocket-chip/riscv-tools/riscv-gnu-toolchain/build/build-gcc-newlib  folders?

Thanks Maxim,

The error has been disappeared after removing "CPATH" environment from my shell configuration.
