Most likely, I'm using 9.2 from crosstool: x86_64-linux-gcc (GCC) 9.2.0 crosstool is a handy way to install GCC for kernel compilations, here are my notes: listings: https://www.kernel.org/pub/tools/crosstool/ wget https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/x86_64-gcc-8.1.0-nolibc-x86_64-linux.tar.xz pushd /opt/cross/ tar -xf ~/tmp/crosstool/x86_64-gcc-8.1.0-nolibc-x86_64-linux.tar.xz In top level create GNUMakefile: CROSS_COMPILE=/opt/cross/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- include Makefile -- https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches _______________________________________________ ath10k mailing list [email protected] http://lists.infradead.org/mailman/listinfo/ath10k
