Ga"el, All,

On 2016-11-22 15:53 -0500, Gaël PORTAY spake thusly:
> Make may throw an error (but ignored) trace when cleaning up the
> rootfs.
> 
> The target-finalize rule intends to remove the folder
> `$(TARGET_DIR)/usr/share' but this directory may still contain items
> (such as the `udhcpc' helper script) and causes the rmdir to fail.
> 
> The stderr output is redirected to /dev/null but it returns and error
> which is escaped by the leading `-'; but make reports an ignored-error.
> 
> See the log below:
> $ make
> (...)
> rm -rf (...)/target/usr/share/gtk-doc
> rmdir (...)/target/usr/share
> rmdir: failed to remove '(...)/target/usr/share': Directory not empty
> make[1]: [Makefile:650: target-finalize] Error 1 (ignored)
> find /(...)/target -type f \( -perm /111 -o -name '*.so*' \) -not \( -name 'libpthread*.so*' -o -name 'ld-*.so*' -o -name '*.ko' \) -print0 | xargs -0 (...)/host/usr/bin/arm-buildroot-linux-uclibcgnueabihf-strip --remove-section=.comment --remove-section=.note 2>/dev/null || true
> 
> This patch apply the same rule at the instruction immediately after:
> * redirecting stderr to /dev/null (already done) and
> * executing true if the `rmdir' instruction fails.
