Installing Eienstien on X64_86 Linux machines??

x86_64-pc-linux-gnu not found??????
Upgraded my lab that had P4 units with come older AMD 64 FX machines. The einstein fails with the above message, but my home machine with an AMD 64 Phenom II CPU installed it some time ago.
I found a mesage from 2007 that talked about creating an app_info.xml file and copying some files, but that made no changed.
Then tried copying some file from the einstein directory on my phenom machine, but run into a missing lib file. Anyone have a complete solution for this?
What is the issue with getting a true 64 bit version?

E@H apps are all 32 bit. Apparently there is insignificant performance gain with a 64 bit app. 32 bit apps run quite happily on a 64 bit OS as long as the required 32 bit shared libraries are installed as well. Apparently, different Linux distros have different policies about whether or not these libraries are there by default. There is no need for AP (anonymous platform) workarounds and so app_info.xml is not relevant here.
You might like to check out the BOINC Wiki entry about this. I'm guessing this may be the reason for your problem.

As a follow up. I tried to run the program in the einstein project directory, and it gave an error of a missing /lib/ld-linux.so.2 file. On my phenom machine this directory has lots of files, on the ones in my lab it currently just subdirectories and 1 linked file.
I found that this file is part of glibc.i686, so
yum install glibc.i686
adds the file.
On a machine that has not had einstein install before adding the files, the program installs correctly with no issues and downloads units.
On a machine that had it installed before and got the message that no 64 bit version existed, I did a number of things and it eventually did get a unit running. Reset project, restarted boinc, and did a full reboot.
On this machine, I installed files, and did a restart of boinc and a reset of einstein, but it still isn't downloading units. This may be one of the request being to soon, so it may download in a while. Could also be it has enough work from the other projects that no more work needs to be downloaded at this time?
As far as I could see, all

As far as I could see, all your (many :-) ) PCs now have tasks, right?
