libtool tries to guess the --tag value based on CC/CXX environment variables and the compile commandline generated by makefiles. This heuristics however fails when we construct CC variables in OE and add security flags to it, especially -fPIE -pie which are added by external compilers e.g. clang particularly. It fails because libtool removed PIE flags from compiler cmdline intelligently if it figures out that its building a library, which means that the CC variable passed from cmdline does not match with the compiler cmdline constructed by libtool and we end up with errors like | arm-bec-linux-musleabi-libtool: compile: unable to infer tagged configuration | arm-bec-linux-musleabi-libtool: error: specify a tag with '--tag' This works with internal gcc toolchain because we configure gcc for PIE when hardening is selected and dont pass -fPIE -pie options explicitly but this is not an option for clang, and some external gcc toolchains using older gcc This patch adds the --tag option to help libtool set correct tags in packages where it cant get it right via its heuristics (From OE-Core rev: 0505075ae8d339ba097aebb82b4d0ae62f87c0a9) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

SUMMARY = "A portable foreign function interface library"
|
|
DESCRIPTION = "The `libffi' library provides a portable, high level programming interface to various calling \
|
|
conventions. This allows a programmer to call any function specified by a call interface description at run \
|
|
time. FFI stands for Foreign Function Interface. A foreign function interface is the popular name for the \
|
|
interface that allows code written in one language to call code written in another language. The `libffi' \
|
|
library really only provides the lowest, machine dependent layer of a fully featured foreign function interface. \
|
|
A layer must exist above `libffi' that handles type conversions for values passed between the two languages."
