Hello, I am trying to emerge gettext using crossdev, however, gettext
generates .la files, and those files refer to /usr/lib and not to my crossdev root.

# ARCH=arm armv7a-hardfloat-linux-gnueabi-emerge -v gettext
...
-hardfloat-linux-gnueabi/tmp/portage/sys-devel/gettext-0.19.5.1/image//usr/lib -L/usr/lib -lintl -lc -liconv -O2 -Wl,-soname -Wl,libgettextlib-0.19.5.1.so -o .libs/libgettextlib-0.19.5.1.so
/usr/libexec/gcc/armv7a-hardfloat-linux-gnueabi/ld: skipping incompatible /usr/lib/libc.so when searching for -lc
/usr/lib/libc.a: error adding symbols: File format not recognized
collect2: error: ld returned 1 exit status
...

Is there a way for me to make gettext generate correct .la fies ?

Regards,

Even

That kind of thing should be handled by the --sysroot parameter to ./configure.
ie: it should be addressed (already, I'd hope) in ebuild-space.

I'd ask in #gentoo-embedded on IRC: chat.freenode.net, before filing a bug.

If you want to dig into configure (autoconf, automake; the underlying autotools) as well as libtool, then ##workingset is the channel.

For integration into ebuilds, #gentoo-dev-help.

HTH,

Hi,

thank you for your response. It seems I cannot see chat.freenode.net,

I am thinking I could run configure,
* Changing --prefix (Used to be /usr)
* Adding --with-sysroot

Like below,

But I am uncertain as to which emerge command I should emit to continue the build afterwards.

Any pointers.

Regards,

Even

Damn, missed the follow-up; sorry Even.

Try chat.freenode.org instead; here's the freenode webpage.

That looks reasonable, though the prefix should be taken care of by crossdev, for toolchain packages -- binutils and gcc at least; sometimes libc is done in the sysroot, sometimes just a normal package.
Not sure what crossdev does with it, though it does handle glibc et al as part of the setup (so likely in the cross-root.)

For something like gettext, I'd have expected it to use a standard prefix of /usr; though it is affected by sysroot, it's not a toolchain package in the normal sense. (It shouldn't care about CTARGET, which only ever applies to cross-toolchain packages.)
I could be wrong though; check with #gentoo-embedded or #gentoo-dev-help

Hmm you really want this to work properly from ebuild-space; but you can use the ebuild command, though you need FEATURES=keepwork I think it is, or you won't be able to retry from where you left off.
Check with #gentoo-dev-help

You can use EXTRA_ECONF_ARGS (again, check) to add more parms to the ./configure line, if the ebuild inherits from autotools.eclass (I think: don't think it's eutils.)

One thing:
Code:
--cache-file=/usr/armv7a-hardfloat-linux-gnueabi/tmp/portage/sys-devel/gettext-0.19.5.1/work/gettext-0.19.5.1-.default/config.cache
looks like a broken path; I'd have expected ../gettext-0.19.5.1/.default/config.cache.
If that's just manual typing, no worries. I could be wrong ofc: check with ##workingset
