looks like they renamed the file: https://sourceforge.net/projects/expat/files/expat/2.1.0/expat-2.1.0-RENAMED-VULNERABLE-PLEASE-USE-2.3.0-INSTEAD.tar.gz/download

The following patch changes the expat version to 2.4.1 as suggested by bitninja at https://forum.micropython.org/viewtopic.php?f=16&t=11188.

Save the snippet as ~/patchfile, cd esp-open-sdk and patch -p1 < patchfile. This patch should be applied beforemake runs the bootstrap command in crosstool-NG to ensure the generated scripts are all built with the new settings from expat.in. It works for me if I apply the patch on a freshly cloned folder before I run make.

Could we integrate this into the next release?

@mrx23dot you may want to use this fork.

[glenn20]

Thanks - I've been experimenting with different forks - but that one looks nice and complete.

Alternately, a fork with the minimal set of changes to get a clean build on Ubuntu 21.10 of an apparently working toolchain can be found here:

https://github.com/pfalcon/esp-open-sdk/pull/391 https://github.com/ChrisMacGregor/esp-open-sdk/tree/builds-on-Ubuntu-21.10 Tarball of built toolchain: https://github.com/ChrisMacGregor/esp-open-sdk/releases/tag/builds-on-Ubuntu-21.10

A maintained fork with more-current versions of things, such as https://github.com/esp-open-sdk/esp-open-sdk or https://github.com/someburner/esp-open-sdk, may be a better option. I'm offering this minimally-tweaked option for those who prefer that, or for comparison purposes if for some reason the newer tools don't work for you, or whatever.

I used your folk on Ubuntu22.04. But i got this error:

Your fork is the best I've tried. gcc is ready.
