It would at least warrant a warning in the menuconfig, such as: if LIBC_eglibc && LIBC_LOCALES comment "Warning! this only works if this machine and the target:" comment " - are the same bitness" comment " - and have the same requirements for the alignment of uint32_t." comment " You will have to check by yourself (for now)." endif # glibc && locales Plus, see comments inlined below... > Signed-off-by: "BenoÃt THÃBAUDEAU" <benoit.thebaudeau@advansee.com> > > diff --git a/scripts/build/libc/glibc.sh b/scripts/build/libc/glibc.sh > --- a/scripts/build/libc/glibc.sh > +++ b/scripts/build/libc/glibc.sh > @@ -63,7 +63,58 @@ > } > > # Build and install the libc locales > -# Not yet supported > do_libc_locales() { > - : > + local src_dir="${CT_SRC_DIR}/glibc-${CT_LIBC_VERSION}" > + local -a extra_config > + > + mkdir -p "${CT_BUILD_DIR}/build-localedef" > + cd "${CT_BUILD_DIR}/build-localedef" > + > + CT_DoLog EXTRA "Configuring C library localedef" > + > + if [ "${CT_LIBC_EGLIBC_HAS_PKGVERSION_BUGURL}" = "y" ]; then > + extra_config+=("--with-pkgversion=${CT_PKGVERSION}") > + [ -n "${CT_TOOLCHAIN_BUGURL}" ] && extra_config+=("--with-bugurl=${CT_TOOLCHAIN_BUGURL}") > + fi > + > + CT_DoLog DEBUG "Extra config args passed: '${extra_config[*]}'" > + > + # ./configure is misled by our tools override wrapper for bash > + # so just tell it where the real bash is _on_the_target_! > + # Notes: > + # - ${ac_cv_path_BASH_SHELL} is only used to set BASH_SHELL > + # - ${BASH_SHELL} is only used to set BASH > + # - ${BASH} is only used to set the shebang > + # in two scripts to run on the target > + # So we can safely bypass bash detection at compile time. > + # Should this change in a future eglibc release, we'd better > + # directly mangle the generated scripts _after_ they get built, > + # or even after they get installed... eglibc is such a sucker... > + echo "ac_cv_path_BASH_SHELL=/bin/bash" >>config.cache > + > + # Configure with --prefix the way we want it on the target... > + > + CT_DoExecLog CFG \ > + CFLAGS="-O2 -fno-stack-protector -U_FORTIFY_SOURCE" \ Although, we are building for the build machine here, not for target, -U_FORTIFY_SOURCE should be conditional on !

Wait! Does that mean we do build a complete glibc just for the sake of having a single binary 'localedef' ? Woosh... I'm OK with that if that's what it takes to have locales on the target, but we should definitely try to find a better make target later, if possible. > + # The target's endianness and uint32_t alignment should be passed as options > + # to localedef, but glibc's localedef does not support these options, which > + # means that the locale files generated here will be suitable for the target > + # only if it has the same endianness and uint32_t alignment as the host's. > + > + CT_DoLog EXTRA "Installing C library locales" > + CT_DoExecLog ALL make ${JOBSFLAGS} \ > + install_root="${CT_SYSROOT_DIR}" \ > + localedata/install-locales > } > Otherwise, looks good.
