x86 - How to install ia32-libs in Ubuntu 14.04 LTS (Trusty Tahr)

Question

I installed Ubuntu 14.04 (Trusty Tahr) yesterday. Everything seems OK. But when I tried to compile some C code, I encounter the following error. The error seems to be due to the OS lacking the 32-bit architecture support. The error output is as following:

/usr/bin/ld: i386 architecture of input file `./libsc.a(ftl_msg.o)' is incompatible with i386:x86-64 output
/usr/bin/ld: i386 architecture of input file `./libsc.a(libsc_debug.o)' is incompatible with i386:x86-64 output
/usr/bin/ld: i386 architecture of input file `./libsc.a(libsc_str.o)' is incompatible with i386:x86-64 output
/usr/bin/ld: i386 architecture of input file `./libsc.a(libsc_cfg_common.o)' is incompatible with i386:x86-64 output

I used to apt-get install ia32-libs when I was using Ubuntu 12.04 (Precise Pangolin). But what I know is that Ubuntu has removed the ia32-libs since Ubuntu 13.10 (Saucy Salamander). How can I fix this problem?

Answer 1

You can try this to install the 32-bit library (not all in ia32-libs):

sudo  apt-get install program:i386

sudo dpkg --add-architecture i386 may be required (if you haven't ever run that).

Or if you want to install the whole ia32-lib instead, try the following order:

sudo -i
cd /etc/apt/sources.list.d
echo "deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list
apt-get update
apt-get install ia32-libs

---

PS: In this way, you can install ia32-libs. However, we add the source of 13.04 instead, so, there may be some unknown problem. After installing ia32-libs, I recommend you to remove the ia32-libs-raring.list in /etc/apt/sources.list.d, and do sudo apt-get update.

If you want to fix the dependency of Android SDK, you can try this bellow:

sudo apt-get install -y libc6-i386 lib32stdc++6 lib32gcc1 lib32ncurses5 lib32z1
