From da4b98447573daf77829811e95e3772e8a296934 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rapha=C3=ABl=20M=C3=A9lotte?= Date: Thu, 2 Sep 2021 20:17:26 +0200 Subject: [PATCH] Use CC instead of LD for OBJCOPY MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When cross-compiling for mips targets using Buildroot, using LD for partial linking fails in the following way: /tmp/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mips64el-buildroot-linux-uclibc/8.4.0/../../../../mips64el-buildroot-linux-uclibc/bin/ld: build/release/libmupdf.a(Dingbats.cff.o): ABI is incompatible with that of the selected emulation /tmp/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mips64el-buildroot-linux-uclibc/8.4.0/../../../../mips64el-buildroot-linux-uclibc/bin/ld: failed to merge target specific data of file build/release/libmupdf.a(Dingbats.cff.o) To fix it, use CC instead of LD for partial linking. 'nostdlib' has to be added, or it will try to use GCC libraries for partial linking and fail with 'cannot find -lgcc_s'.
