toolchain-build's Issues

Failure to compile glibc abiv1 (and abiv2) toolchain in Ubuntu Xenial chroot

I attempted to build the toolchain using an Ubuntu Xenial chroot configured as follows:

sudo apt install -y debootstrap
debootstrap xenial xenial-chroot
sudo chroot xenial-chroot add-apt-repository universe
sudo chroot xenial-chroot apt update
sudo chroot xenial-chroot apt install -y build-essential wget unzip bc git gawk
sudo chroot xenial-chroot apt install -y texinfo bison flex libgmp-dev libmpfr-dev libmpc-dev
sudo chroot xenial-choot
# Inside Xenial chroot
git clone https://github.com/c-sky/toolchain-build
cd toolchain-build

As with #2 and #3 - I have the same mklink issue when running init:

./build-csky-gcc.py --abi=abiv1 --tos=linux --libc=glibc --init

Resulting in:

...
<-- component 'mklink' source code url ['/root/toolchain-build/source//mklink'] is not valid

Building is sucessful with the following command until the glibc component:

./build-csky-gcc.py --abi=abiv1 --tos=linux --libc=glibc

====> components chain = ['binutils', 'gcc.0', 'linux-libc-headers', 'glibc', 'gcc', 'gdb', 'mklink']

====> start building component 'binutils' ... ...
<-- current component 'binutils.0' has finished

====> start building component 'gcc.0' ... ...
--> current building platform/os is "linux2"
<-- current component 'gcc.0' has finished

====> start building component 'linux-libc-headers' ... ...
<-- current component 'linux-libc-headers.0' has finished

====> start building component 'glibc' ... ...

I wondered if the same would happen when building the v2 abi:

./build-csky-gcc.py --abi=abiv2 --tos=linux --libc=glibc

This command also had an error:

How to compile a compiler that runs on other architectures

I want to cross-compile compilers that run on other architectures, currently my environment is Ubuntu on AMD64, can I compile compilers that run on Windows on AMD64 on this?

I tried to change the --host parameter in the script, but it doesn't seem to work, the compiled Xuantie-800-gcc-elf-newlib-Win32 is still an executable under Linux

python3 . /build-csky-gcc.py csky-gcc --src . / --triple csky-unknown-elf --jobs=8 --host=Win32 --rebuild

Replace git@ with https://

The current build-csky-gcc.py attempts to clone with the git command using [email protected]. This invokes the ssh command which required credentials. I replaced it with git clones that use https rather than git over ssh. I don't think this is strictly needed but I found it useful:

Failure to compile uclibc-ng abiv1 toolchain in Ubuntu Xenial chroot

I attempted to build the toolchain using an Ubuntu Xenial chroot configured as follows:

sudo apt install -y debootstrap
debootstrap xenial xenial-chroot
sudo chroot xenial-chroot add-apt-repository universe
sudo chroot xenial-chroot apt update
sudo chroot xenial-chroot apt install -y build-essential wget unzip bc git

As with #2, I have the same mklink issue when running init:

./build-csky-gcc.py --abi=abiv2 --tos=linux --libc=uclibc-ng --init

Building is sucessful with the following command until the uclibc-ng component:

./build-csky-gcc.py --abi=abiv2 --tos=linux --libc=uclibc-ng

The final component uclibc-ng fails to build with the following error:

How to compile on macOS M1?

Is it possible to build this toolchain under macOS on a M1?

I ran the script as:

./build-csky-gcc.py csky-gcc --src ./ --triple csky-unknown-elf

but it eventually gives the error:
