This function is compiling a native binary, however its operating largely inside a target or nativesdk shell environment. It does tricks by passing toolchain-native.cmake to provide native overrides for cmake, which works for most of variables of interest besides LDFLAGS. In the toolchain.cmake files on OE we do not override LDFLAGS but append to it via CMAKE_CXX_LINK_FLAGS or CMAKE_C_LINK_FLAGS, which causes problems because LDFLAGS for nativesdk will contain --dynamic-linker option pointing into nativesdk string and when doing target build it will use the LDFLAGS from target environment which might work if it does not contain conflicting flags. Currently prepare_builtins binary durin nativesdk build ends up with [Requesting program interpreter: /usr/local/oe-sdk-hardcoded-buildpath/sysroots/x86_64-yoesdk-linux/lib/ld-linux-x86-64.so.2] This is because LDFLAGS for nativesdk contain the --dynamic-linker flags pointing into this path. Target builds for musl targets also end up with similar problems So lets pass LDFLAGS=BUILD_LDFLAGS to fix this problem Should toolchain.cmake class define CMAKE_EXE_LINKER_FLAGS, CMAKE_SHARED_LINKER_FLAGS, CMAKE_MODULE_LINKER_FLAGS etc. as well is a question that deserve a separate discussion Signed-off-by: Khem Raj <raj.khem@gmail.com> Cc: Ross Burton <ross.burton@arm.com> --- meta/recipes-devtools/clang/libclc_git.bb | 1 + 1 file changed, 1 insertion(+)
