After hooking up the outputs in QJackCTL and the MIDI from VKeyBD to RTSynth in aconnectgui, I was able to play a wonderful-sounding guitar from my keyboard. As a test, I fired up QJackCTL, VKeyBD, aconnectgui (all native 64-bit applications), and the JACK version of RTSynth. That’s it! Your 32-bit binaries and any included libraries should now be functional.
Running 32 bit on 64 bit linux install#
If you get an error about an asound library being uninstallable, you should be able to fix it with the command sudo apt-get install libasound2=1.0.15-3ubuntu4. The command sudo apt-get install ia32-libs will install the libraries. The IA32 libraries provide everything you need to run 32-bit binaries. 32-bit binariesĪs it turns out, the good people of Debian (on which Ubuntu is based) have already solved the problem of running 32-bit binaries on 64-bit Linux. The good news is, Sun doesn’t have the only the Java Runtime Environment (JRE) on the block. In fact, Sun’s Java doesn’t even work with the plugin wrapper we will use for Flash. These pages require Java, and Sun, like Adobe, is rather tardy about supporting 64-bit computers. The National Weather Service has looping weather radar pages that show the movement of storms and rain. Where I live, we have a saying: “If you don’t like our weather, stick around a few minutes, it’ll change.” Since our weather is so variable, we depend on weather radar more than forecasting for scheduling events affected by weather. Normally I would set up a virtual machine for such a “problem program,” but none of the virtual machine applications that run on today’s hardware can meet the processing and latency requirements for sound work (especially physical modeling). It is available as a binary only for 32-bit Linux.
Running 32 bit on 64 bit linux software#
Since I am also a (very amateur) musician, I also wanted to install one of my favorite software synthesizers, RTSynth, a physical modeling synthesizer which, alas, is free only as in beer because of concerns over patents on physical modeling. Apparently, the only plugin available for Flash video was the open source player Gnash, but it would not even display the YouTube video player. The joyride came to an end when I tried to find a video for one of my favorite new songs on YouTube. I was writing documents, browsing the Web, chatting with Ekiga, and listening to music almost as soon as Ubuntu was installed. Even the restricted drivers, such as the ATI frglx and the Atheros MadWifi drivers, came precompiled. Most of the applications in Ubuntu’s repositories have been recompiled for 64-bit support, so productivity is not a problem. The commands in this article are for Ubuntu 8.04, but the software described should work for any Debian-based 64-bit Linux distribution.īeing a technology enthusiast, I decided to install the 64-bit version of Ubuntu on my new Toshiba laptop, equipped with an AMD Turion 64 X2 dual core processor. Here’s a look at three cases where running 32-bit applications on 64-bit hardware can accomplish what you need. It is possible, however, to run 32-bit Linux binaries natively under 64-bit Linux kernels. Most 64-bit-capable computers aren’t making use of these capabilities, but instead are put to work running 32-bit operating systems, usually because of a lack of applications for 64-bit operating systems, since applications must be recompiled and in some cases rewritten for 64-bit operation.

While 32-bit processors can address 4 gigabytes of RAM, a 64-bit processor can address 16 exabytes, or almost 17.2 billion gigabytes, of RAM. Almost any new processor from Intel or AMD has the AMD long mode extensions, allowing the processor to use 64-bit registers. 64-bit computing is as prevalent today as multicore computing.
