It is still higher than the 328 cmake-based package we have of course, but I wouldn't say that meson is "sufficiently rare" :-) Annoying that this problem hasn't been resolved in upstream ninja :-/ Thomas -- Thomas Petazzoni, co-owner and CEO, Bootlin Embedded Linux and Kernel engineering and training https://bootlin.com _______________________________________________ buildroot mailing list buildroot@buildroot.org https://lists.buildroot.org/mailman/listinfo/buildroot
