Nothing looks wrong here. Are you sure that grep
BR2_PACKAGE_LIBQUIC .config shows that this package is enabled?
For a package to build, there's a few rules to respect:
- the option must be named BR2_PACKAGE_<FOO>
- the package must be in package/<foo>/<foo>.mk
- the variables in foo.mk must be prefixed by <FOO>
All three conditions seem to be respected on what you're showing.
Unrelated, but the LIBQUIC_SOURCE variable is useless, since you have
specified LIBQUIC_SITE_METHOD = git. But that's definitely not the
reason why this package doesn't build.
Best regards,
Thomas
