From b658eae77feebf46a9e5f76864e1d9cbc695c91a Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Sat, 11 Sep 2021 21:03:34 +0200 Subject: [PATCH] uboot-sunxi: Fix build with GCC-10 as host compiler The package uses the host compiler to build the dtc binary. With gcc-10, the option -fno-common is now the default behavior. Thus multiple definitions of the same variable are now forbidden and results in following error during linking: HOSTLD scripts/dtc/dtc /usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x10): multiple definition of `yylloc'; scripts/dtc/dtc-lexer.lex.o:(.bss+0x0): first defined here collect2: error: ld returned 1 exit status The easiest workaround is to add the upstream commit 018921ee79d3 ("Remove redundant YYLOC global declaration").
