I'm trying to install the ATLAS library (v3.10.1) on my Tegra3 ARM CPU (cortex-a9) under an Ubuntu 11.04 OS but I cannot passed the configuration step..
When I launch the "./configure" executable I get this following output:
make: `xconfig' is up to date.
./xconfig -d s /home/ubuntu/Libraries/ATLAS/build/.././ -d b /home/ubuntu/Libraries/ATLAS/build -D c -DATL_ARM_HARDFP=1 -Ss ADdir /Libraries/ATLAS/build/ARMHARDFP -Si archdef 0 -Fa alg -mfloat-abi=hard

Cannot detect CPU throttling.

So, I have three questions:
First: Why "Bad CPU MHZ value=0, res='CPU MHZ=0" ? I precise that the CPU throttling of all the cores is set on 0 (I checked the /sys/devices/system/cpu/cpu*/cpufreq/throttle files). Is there a way to pass the clock frequency of the ARM cpu as argument ?
Second: Why "sh: Syntax error: EOF in backquote substitution" ?
Third: "Unable to find usable compiler for ICC; abortingMake.." Is there a way to say at the ./configure executable to not looking for ICC ? Because I'm trying to build ATLAS on ARM therefore ICC is not available.
Thanks in advance for your help !

The ATLAS configuration environment is broken for ARM, and not very fault tolerant in general:
first it attempts to determine system performance by grepping in /proc/cpuinfo (which has never been intended for anything other than some human-readable information dump). You can override this by specifying a frequency on the configure command line: -m <MHz>
then it probes for whether power management is enabled - if it is, it bails out again. Can't see a configure option, but if you make ProbeThrottle() in CONFIG/src/backend/archinfo_linux.c return 0, it gets past that.
You're then hit by the fact that there seems to have actually been some work done for some Cortex-A8 platform several years ago, and the compiler flags set by default for ARMv7 in CONFIG/src/atlcomp.txt include -mfloat-abi=softfp. Change this to 'hard' and it will actually work on a modern ARM Linux distribution.
The syntax error is fallout from trying to look for compilers in /opt/bin and /opt/sbin and not handling errors.
With the above workarounds, I don't see any ICC errors, and the build gets a fair bit along before crashing and burning.
In short, there will be some porting effort required in order for it to work properly on ARM. Maybe you can start by sending an error report to their developer mailing list?
