[Buildroot] [PATCH 02/14] libenca: new package

[Yann E. MORIN <yann.morin.1998@free.fr>]

Maxime, All,

At long last, my comments below... ;-)

Since I'm basing my review not on this patch, but on the one you have in
your repo, there might be some discrepancies...

On 2014-01-12 18:53 +0100, Maxime Hadjinlian spake thusly:

Muarf! :-)

Maybe it would be nice to at least Cc gimli, out of courtesy?

Your repo now has a commit log + SoB-line, but it does not explain why
you want to avoid buildign the tools. Please expand on this in the
patch' commit log (what you said on IRC is OK, I guess).

Also, your patch touches Makefile.in. You should modify Makefile.am to
remove the tools, and set LIBENCA_AUTORECONF=yes.

Or better yet: prepare a patch for upstream that adds the possibility to
enable/disable the tools:
    ./configure --enable-tools
    ./configure --disable-tools

That way, we can get rid of the patch altogether (and _AUTORECONF) when
upstream releases a new version and we bump to it.

This patch in your repo is still missing a commit log + SoB-line.

Also, it looks like it is an install fix, not a clean fix (name of the
patch).

Again, you're touching Makefile.in. You should modify Makefile.am and
set AUTORECONF=yes.

It seems you dropped that one from your repo.

Here I'm pasting the content of your repo:

> +LIBENCA_VERSION = 1.15
> +LIBENCA_SITE = $(call github,nijel,enca,$(LIBENCA_VERSION))
> +LIBENCA_INSTALL_STAGING = YES
> +LIBENCA_LICENSE = GPLv2

Why do you need to fake the prefix? Doesn't DESTDIR work as expected?

> +LIBENCA_CONF_ENV += ac_cv_file__dev_random=yes \
> ac_cv_file__dev_urandom=yes \
> ac_cv_file__dev_arandom=no \
> ac_cv_file__dev_srandom=no

Check indentation on those three lines: they appear to be right-shifted.
Myabe your tabls are too small in your editor? We're using 8-space wide
tabs.

Please split this long line before each -e:
    cd $(@D)/tools && sed -e 's/^#define \([A-Z0-9_]*\) \(.*\)/@\1@ \2/' \
                          -e 's/"//g' -e 's/NULL$$//' -e 's/ /\//' \
                          -e 's/^\(.*\)$$/s\/\1\//' ../iconvenc.h \

Should it be a POST_CONFIGURE, or a _PRE_BUILD hook? But we don't have a
_PRE_BUILD HOOK, so let it be a _POST_CONFIGURE.
