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?
The problem is that in many cases the packages are multiarch already so the i386 package is not available, but other packages still depend on the i386 package only. This is a problem in the repository, and the managers of the repos should fix it
Install gcc multiple library.
sudo apt-get install gcc-multilib
The best answer I have ever seen is How to run 32-bit applications on Ubuntu 64-bit?
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
sudo ./adb
These alternative libraries worked for me:
sudo apt-get update
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
I got it finally! Here is my way, and I hope it can help you :)
sudo apt-get install libc6:i386
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
rm /etc/apt/sources.list.d/ia32-libs-raring.list
apt-get update
exit
sudo apt-get install gcc-multilib
I don't know the reason why I need to install these, but it works on my computer. When you finish installing these packages, it's time to try. Oh yes, I need to tell you. This time when you want to compile your code, you should add -m32 after gcc, for example: gcc -m32 -o hello helloworld.c. Just make clean and make again. Good luck friends.
PS: my environment is: Ubuntu 14.04 64-bit (Trusty Tahr) and GCC version 4.8.4. I have written the solution in my blog, but it is in Chinese :-) - How to compass 32bit programm under ubuntu14.04.
A solution is add the corresponding Debian package way to your repository. For this, type the below commands:
echo "deb ftp.us.debian.org/debian wheezy main" >> /etc/apt/sources.list
sudo apt-get update
sudo apt-get install ia32-libs-i386
The first line writes in the end of the sources.list file the package way.
This works for me. I wish that helps you.
Simply install the 32-bit version of the program, instead of the 64-bit version.
This is much safer than installing packages that are not intended for the distribution at hand.
I got this suggestion from the Google Earth installation instructions for Ubuntu 14.04.
Google Earth used to employ ia32-libs under 64-bit Ubuntu 12.04.
Quoting webupd8.org:
The ia32-libs package is no longer available in Ubuntu, starting with Ubuntu 13.10. The package was superseded by multiarch support so you don't need it any more, but some 64bit packages (which are actually 32bit applications) still depend on this package and because of this, they can't be installed in Ubuntu 14.04 or 13.10, 64bit. [...]
The "fix" or more specifically the correct way of installing these apps which depend on ia32-libs is to simply install the 32bit package on Ubuntu 64bit. Of course, that will install quite a few 32bit packages, but that's how multiarch works.
The problem with some programs (like Google Earth) is that the 32-bit package does not support multiarch. Consequently, some 32-bit dependencies need to be installed manually to make the 32-bit version of the program run on Ubuntu 64-bit.
sudo dpkg --add-architecture i386 # only needed once
sudo apt-get update
sudo apt-get install libfontconfig1:i386 libx11-6:i386 libxrender1:i386 libxext6:i386 libgl1-mesa-glx:i386 libglu1-mesa:i386 libglib2.0-0:i386 libsm6:i386
sudo -i
cd /etc/apt/sources.list.d
echo "deb http://archive.ubuntu.com/ubuntu/ precise main restricted universe multiverse" >ia32-libs-raring.list
apt-get update
apt-get install ia32-libs
rm /etc/apt/sources.list.d/ia32-libs-raring.list
apt-get update
exit
If you are in China, you can modify "raring" to "precise" (for Ubuntu 13.04 (Raring Ringtail) and Ubuntu 12.04 LTS (Precise Pangolin), respectively). I installed Beyond Compare on Ubuntu 14.04 (Trusty Tahr).
I had the same problem as above and Eclipse suggested installing:
Hint: On 64-bit systems, make sure the 32-bit libraries are installed:
"sudo apt-get install ia32-libs"
or on some systems,
"sudo apt-get install lib32z1"
When I tried to install ia32-libs, Ubuntu prompted to install three other packages:
$ sudo apt-get install ia32-libs
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package ia32-libs is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
lib32z1 lib32ncurses5 lib32bz2-1.0
E: Package 'ia32-libs' has no installation candidate
$
$ sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
With Android Studio and intellij, I also had to install the 32bit version of libstdc++6:
sudo apt-get install lib32stdc++6
For me, I have to run
sudo dpkg --add-architecture i386
before running Mike Tang's answer. Otherwise, I can't install ia32-libs.
