I'm Sorry, I misunderstood the 'instructions' you said. The process of
making the toolchain is a little complicated. So I made a script used to
generate the toolchain from source codes. The content of the script is
as follows:
I successfully generated a cross compilation toolchain with this script.
I ran this script in a UBI8 image (iow RHEL8), with the
codeready-builder-for-rhel-8-x86_64-rpms repo enabled and the
following packages installed:
# subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
# dnf install bison diffutils file flex gcc gcc-c++ git gmp-devel
libtool make python3 rsync texinfo wget xz zlib-devel
I'm sorry. I forgot to give the dependencies for build the cross
compilation toolchain. These
dependencies can be added into the documentation for LoongArch. Thanks a
lot.
The script below works, but it is really better to run it with -e.
# bash -e $script
Yes, thanks. The script will run for a long time. It is better to run it
with -e in order to exit quickly when an error has occured.
