A kvx toolchain can be built using:
# install dependencies: texinfo bison flex libgmp-dev libmpc-dev libmpfr-dev
$ git clone https://github.com/kalray/build-scripts
$ cd build-scripts
$ source last.refs
$ ./build-kvx-xgcc.sh output

I would like to build the kvx-xgcc to compile and test the linux
kernel, but it reported a compile error.
I wonder what version of gcc you are using.

My build environment:
VERSION="20.04.2 LTS (Focal Fossa)"
gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04)


Compile error:
$ ./build-kvx-xgcc.sh output

../../binutils/libiberty/fibheap.c: In function ‘fibheap_replace_key_data’:
../../binutils/libiberty/fibheap.c:38:24: error: ‘LONG_MIN’ undeclared

What SHA1 of https://github.com/kalray/build-scripts are you using?

We are building our toolchain on Ubuntu 18.04 / 20.04 and 22.04 without 
issues, I don't understand why it does not work for you, although indeed 
the error log you are having pops out on my search engine and seems to 
be some well known issue.

If the build-script does not work for you, you can still use the 
pre-built toolchains generated by the GitHub automated actions: 
https://github.com/kalray/build-scripts/releases/tag/v4.11.1 ("latest" 
means 22.04)

I hope it will work for you.

Regards,
