automake-1.11 vs. host $perl_threads

automake-1.11 vs. host $perl_threads

[Andrea Adami]

Hi,

in log.do_configure of automake-native-1.11.1-r3.1 I see

checking for perl... /usr/bin/perl
checking whether /usr/bin/perl supports ithreads... yes

In fact I have in my
 /oe/build/tmp/sysroots/i686-linux/usr/share/automake-1.11/Automake/Config.pm

our $APIVERSION = '1.11';
our $PACKAGE = 'automake';
our $VERSION = '1.11.1';
our $libdir = '/oe/build/tmp/sysroots/i686-linux/usr/share/automake-1.11';
our $perl_threads = 1;

Well, that seems just fine but since some days building on a Gentoo
host, whose perl is compiled without threads support (no 'ithreads'
use flag) I trigger a nasty error:

NOTE: package libx11-1_1.4.0-r9.0: task do_configure: Started
ERROR: Logfile of failure stored in:
/oe/build/tmp/work/armv5te-angstrom-linux-gnueabi/libx11-1_1.4.0-r9.0/temp/log.do_configure.4482
Log data follows:
| This Perl not built to support threads

NOTE: package libx11-1_1.4.0-r9.0: task do_configure: Failed

Note that in the host   /usr/share/automake-1.11/Automake/Config.pm I have

our $perl_threads = 0;

So it seems to me that something is getting mixed between perl-native
and perl on host :/

Any idea?

Regards

I found something in run.do_configure of automake-1.11

do_configure() {
        if false
        then
                export
ac_cv_path_PERL="${ac_cv_path_PERL=/oe/build/tmp/sysroots/i686-linux/usr/bin/perl}"
        fi
        autotools_do_configure

}

It comes from


do_configure_prepend () {
        if ${@['true', 'false'][bb.data.inherits_class('native', d)]}
        then
                export ac_cv_path_PERL="${ac_cv_path_PERL=${bindir}/perl}"
        fi
}

test fails...

OK what happens if you get rid  of do_configure_prepend fully ?

 yes, fully removing do_configure_prepend allows e.g. libx11

Bingo!

Intentionally, yes.  There is no dependency on perl-native for 
autoconf/automake and instead on the fake "throwing our hands up" 
perl-runtime-native.

It looks like Poky's handles the issue differently:

http://git.pokylinux.org/cgit/cgit.cgi/poky/tree/meta/recipes-devtools/autoconf/autoconf_2.65.bb
vs.
http://cgit.openembedded.org/cgit.cgi/openembedded/tree/recipes/autoconf/autoconf_2.65.bb


and similarly

http://git.pokylinux.org/cgit/cgit.cgi/poky/tree/meta/recipes-devtools/automake/automake_1.11.1.bb
vs.
http://cgit.openembedded.org/cgit.cgi/openembedded/tree/recipes/automake/automake.inc

Any opinion from autofoo experts?
TIA

After a better inspection, nothing new there.


I suspect the perl issue was originated by me, starting a build in
Ubuntu env (with perl  threads) and having resumed a broken build
after rebooting in Gentoo (no perl threads). That would explain our
$perl_threads = 1; for automake-native.

A fresh build of one hour ago gave our $perl_threads = 0;

Sorry for the noise

Still, is a bit unclear to me why the package was testing host
perl...and recently I read

[oe] [PATCH 1/2] automake_1.11.1.bb: Don't try to execute perl.
( http://lists.linuxtogo.org/pipermail/openembedded-devel/2010-December/027516.html
)

so indeed there is something strange...

Will test the patch and reply
