make build fails (again) with error

[jbrunk1966]

according to a closed issue this error should be solved by updating the sub-modules, but it doesn't help...

updated all build tools and source before

$ cd xuantie-gnu-toolchain
$ git pull --force
$ git submodule update --remote  --force --recursive  
$ make distclean
$ ./configure --prefix=/opt/riscv-toolchain/xuantie --with-cmodel=medany --enable-multilib --disable-gdb
$ make newlib -j$(nproc)

but the build still fails somewhere

Hello, can you confirm whether the csplit tool is installed in your system, if the ubuntu system, you can use "apt-get install coreutils" to install.

[jbrunk1966]

yes, csplit ist installed on my System (Apple MacBookAir M2, MacOS 13.3.1a:

macbook-air:xuantie-gnu-toolchain jbrunk$ which csplit
/usr/bin/csplit
macbook-air:xuantie-gnu-toolchain jbrunk$ csplit
usage: csplit [-ks] [-f prefix] [-n number] file args ...

[jbrunk1966]

anyway, i managed to get it working by using the Toolchain provided via brew on MacOS. Even if they do the same it compiles from GIT w/o above issue 🤷

This is due to inconsistencies between GNU csplit and BSD csplit. The Makefile assumes GNU-style messages, so pattern-matching on the string match not found fails when BSD csplit outputs no match. At least as importantly, BSD csplit expects all options to precede the pattern and filename. Finally, it doesn't support the -b flag.

A possible workaround would be to use GNU coreutils rather than system-provided tools to ensure that the assumed output matches the actual output (e.g. by installing coreutils with brew and then prepending the resulting gnubin directory to the front of your path when calling make). I can't vouch that this fixes the build completely on Apple Silicon, but it's a step in that direction.
