Building 32 bit progs/libs on multilib

shoshia · 08-27-2014, 10:11 AM

Hi all
I have installed multilib
run
$/etc/profiled/32env.sh /dont remember exact name/

1. than compile program
but ld linker is executed from x86_64_slackware lib
so question:
is build program/lib 32 bit?

2. It seems i can not use slackbuild script to build 32 bit staff? since
ARCH is found from

PHP Code:



if [ -z "$ARCH" ]; then 
  case "$( uname -m )" in 
    i?86) ARCH=i486 ;; 
    arm*) ARCH=arm ;; 
       *) ARCH=$( uname -m ) ;; 
  esac 
fi

if i just do

PHP Code:



#if [ -z "$ARCH" ]; then 
#  case "$( uname -m )" in 
#    i?86) ARCH=i486 ;; 
#    arm*) ARCH=arm ;; 
#       *) ARCH=$( uname -m ) ;; 
#  esac 
#fi 
ARCH=i486 ;;

code does not compile...

any suggestions..or it is nesessary to have 32 bit installed separately?

Hello,

to build 32-bit softwares on Slackware64/multilib, you must :

1. run the command :

Code:

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

Note the dot in front of /etc/profile.d/32dev.sh (which is equivalent to the command 'source') is required.

2. pass ARCH=i486 to the slackbuild :

Code:

$ ARCH=i486 ./foo.SlackBuild

Also, you can convert existing libraries using convertpkg-compat32 with packages from the 32 bit distribution. For example:

Code:

convertpkg-compat32 -i libgnome-keyring-3.8.0-i486-1.txz

And then install the package using installpkg or upgradepkg --install-new.

(This was not part of multilib, and I needed it for a package.)
