From c2b0fe80e025ebd816cf0447fb11022d3fe57309 Mon Sep 17 00:00:00 2001 From: Matt Weber Date: Sun, 21 Oct 2018 07:21:35 -0500 Subject: [PATCH] package/clang: default linker to the cross GNU By default clang is assuming the system linker /usr/bin/ld. This patchset updates the default to point at the cross toolchain ld. Previously clang had been used on target only, this update is required for host clang/clang++ to be used as a frontend for cross-compiling. Example build command: output/host/bin/clang++ -mcpu=cortex-a53 \ --sysroot //output/staging/ \ -B //output/host/opt/ext-toolchain/ \ foobar.cc -o foobar Cc: Valentin Korenblit Reviewed-by: Romain Naour Signed-off-by: Matthew Weber Signed-off-by: Thomas Petazzoni --- package/clang/clang.mk | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/package/clang/clang.mk b/package/clang/clang.mk index 52e0b98a76..f9d4ae3713 100644 --- a/package/clang/clang.mk +++ b/package/clang/clang.mk @@ -49,7 +49,8 @@ CLANG_CONF_OPTS += \ -DCLANG_INCLUDE_DOCS=OFF \ -DCLANG_INCLUDE_TESTS=OFF -HOST_CLANG_CONF_OPTS += -DLLVM_CONFIG:FILEPATH=$(HOST_DIR)/bin/llvm-config +HOST_CLANG_CONF_OPTS += -DLLVM_CONFIG:FILEPATH=$(HOST_DIR)/bin/llvm-config \ + -DCLANG_DEFAULT_LINKER=$(TARGET_LD) CLANG_CONF_OPTS += -DLLVM_CONFIG:FILEPATH=$(STAGING_DIR)/usr/bin/llvm-config \ -DCLANG_TABLEGEN:FILEPATH=$(HOST_DIR)/bin/clang-tblgen \ -DLLVM_TABLEGEN_EXE:FILEPATH=$(HOST_DIR)/bin/llvm-tblgen -- 2.30.2
