Why is it painful? You have all dependencies packaged that follow semver (not like Go) and it is quite easy to build those packages. Another example here could be nodejs, even though it does not link statically it is just PITA to package since ecosystem is just full of very small libraries that do not really like to cooperate so you need to have tens of different versions of a lib in a repo.

That way you can say that mesa is foreign because it uses LLVM. If there is ever alternative compiler to Rust that is based on GCC and has feature parity, we can definitely consider trying it out.

We also have Fedora CoreOS that uses https://github.com/coreos/afterburn and https://github.com/coreos/zincati that are written in Rust as well and those are core system utilities. I don't think saying "Ditch Python, Ruby, Perl, … from the system components" is useful for anyone since you know that it is not going to happen. > Kevin Kofler > _______________________________________________ > devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx > Fedora Code of Conduct: > https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: > https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: > https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx - -- Igor Raits <ignatenkobrain@xxxxxxxxxxxxxxxxx> -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEcwgJ58gsbV5f5dMcEV1auJxcHh4FAl7bcdkACgkQEV1auJxc Hh6Aqg//bbeyDzTLPVhN41P7TU5LeA2d1c/Ya2tjbpvWf3VaWsJ26UDdLUyIXw2c r4/C3Kkda7qGHmOSjLRlBvzEMe3e7wO+Xi+16ZyTex6+2M1bxifAXZHTz1wtkhIW AmdMvyjJbCrzc3jUG3dj3FfE4PWjS58tZYIvG8XEcRxoyvWOsMRqdaxP0V9Frhr7 9hxULUenGpVzvXz+z8/s7rosN4yqTotv1HCFRCworHhXXErVzEy8ha7EjZpGwnyL zDssJ0jB+5eMYk94J2NG5ZwBkOSxBfYMEO4dDLQdMPk6jBEfpZg1jS5wIkbUx3UR fZpitoOs5snIyh46bjL5ldod9lgJ+j7txSle0tpTbeGsPRqVIq+k7NhRI7s24q+R uaJwHDsGRtBaWeTzzykCPlj7kRh/y/fV3TIBzpi5apK1aXxmAZw/RuMXzZK65yFb cGQ79jKanOzRMCD97T+ExiBNpk5Oj0dEF3dWlbHAxoHDc5UFRxyizUPPUNGHooTg qmnssso/a4MoS0/IdTsHpJP62Xm7tGBm9VfIDkK9GFxBZ+L5nj/43yuBxKUMA2s/ pWBZ2FiqzLQ0RyD1IqXsUVyoxm3X66FRywkTgUdg56MQAvZQkppdeoBwoP4kBOdS Yqnt/GC3iq0bt+7Rt7TQudB5fXOKnFL7oGyrx6zAoct3n+F+HNk= =H4dJ -----END PGP SIGNATURE----- _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
