I have Buildroot build my toolchains, using uClibc and musl. I occasionally had problems when switching kernel versions and forgetting to rebuild everything. This might be a dependency issue, not directly related to the toolchain, but since Rustam only tested this using glibc, the restriction seems appropriate. > >> Thanks! >> >> Thomas >> -- >> Thomas Petazzoni, co-owner and CEO, Bootlin >> Embedded Linux and Kernel engineering and training >> https://bootlin.com > > Hope this clarifies, > Regards, > Rustam Kind regards, Andreas _______________________________________________ buildroot mailing list buildroot@buildroot.org https://lists.buildroot.org/mailman/listinfo/buildroot
