[SOLVED] compiling 32bit programs in slackware64

animeresistance · 08-04-2011, 09:44 PM

Hi there!

I'm trying to compile avahi, but i need it in 32 bit to install aldebaran's choregraphe 1.3.3 . I have a multilib slackware64, i had read alien bob's instructions on compiling 32 bit, looks easy. And i was wondering if this modified script is ok, or it needs something more.

echo " # useradd -u 214 -g 214 -c "Avahi" -d /dev/null -s /bin/false avahi"
exit 1
}

cd $PKG
/sbin/makepkg -l y -c n $OUTPUT/$PRGNAM-$VERSION-$ARCH-$BUILD$TAG.${PKGTYPE:-tgz}

Because Aldebaran's choregraphe installer says "wrong ELF class: ELFCLASS64" Wonder if i mixed the libraries

Any idea or comment is welcome

Try using "ARCH=i486 ./avahi.SlackBuild" with the vanilla SlackBuild script and see if it will build the 32-bit version that way. Only use "ARCH=x86_64" when you're doing a 64-bit build.

Hi ReaperX7

I tried to run the command you say, but it says "bash ./avahi.SlackBuild Permission denied" Wonder why, i'm running it with root user...

ReaperX7 · 08-04-2011, 10:59 PM

Probably a permissions error. It's happens when you modify some files at times. Try running "chmod +x avahi.SlackBuild" and trying it again. Usually it's the permission to allow the file to be ran as an executable that gets weird and causes this. You can also Right Click it in the Desktop Environment, click the Permissions tab, and checking the box labeled "Executable".

Hi again ReaperX7.

I used the command "ARCH=i486 ./avahi.SlackBuild" with the vanilla SlackBuild script (i think the vanilla script is the original one from SlackBuilds) and it stops, an error message appears and says that C compiler cannot make executables.

The config.log says that the confdefs.h failed, that program generates a lot of data ..

Thanks for replying. I will continue looking tomorrow.

Any ideas, comments or suggestions are welcome.

Good night

As explained in Alien's wiki, when you need to compile 32-bit software, you first have to configure your shell environment using the command below:

Code:

. /etc/profile.d/32dev.sh

Oh thanks ..

I read Alien Bob blog before, but i think i was too tired and frustated that i made a mistake, now it works.

Thanks a lot guys.

But how do i put the "solved" flag ?

animeresistance · 08-05-2011, 05:35 PM
