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:

1. Download Libusb
2. Libusb Win 10

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?

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

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:

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

I got it finally! Here is my way, and I hope it can help you :)

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.

I had the same problem as above and Eclipse suggested installing:

When I tried to install ia32-libs, Ubuntu prompted to install three other packages:

Download Libusb

With Android Studio and intellij, I also had to install the 32bit version of libstdc++6:

For me, I have to run

before running Mike Tang's answer. Otherwise, I can't install ia32-libs.

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. Acer aspire 5750 drivers for windows 7 64-bit.

Libusb Win 10

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 notsupport 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.

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).

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

A solution is add the corresponding Debian package way to your repository. For this, type the below commands:

The first line writes in the end of the sources.list file the package way.This works for me. I wish that helps you.

Hi everyone, I received the Raspberry Pi model B just yesterday. Now I configured it properly and I'm trying to use the Archos G9 3G Stick to connect the PI tho the Internet. To use the stick with my Mepis Linux installation I must active the connection by Sakis3g and so I've immediately thought to download the script for ARM devices on the Raspberry Pi. But when I ask Sakis3g to connect it answers me:
When I try that command an error windows appears:

Code: Select all

Then, I searched the internet for any answer, and I've found a tutorial. It advises me to install ppp by runningbefore starting the connection process with Sakis3g. It can be the problem, but I have only the 3g stick to connect every device to the internet.
Someone can help me? Thanks.
