ATLAS on ARM配置失敗

Question

我試圖在我的Tegra3 ARM CPU（cortex-a9）上安裝Ubuntu 11.04操作系統下的ATLAS庫（v3.10.1），但是我無法通過配置步驟.. 當我啓動該 「的./configure」 可執行我得到這個輸出如下：

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 

OS configured as Linux (1) 

Assembly configured as GAS_ARM (7) 

Vector ISA Extension configured as NEON (10,1024) 

Architecture configured as ARMv7 (46) 

Bad CPU MHZ value=0, res='CPU MHZ=0

Clock rate configured as 0Mhz 

Maximum number of threads configured as 4 
Parallel make command configured as '$(MAKE) -j 4' 

Pointer width configured as 32 
Cannot detect CPU throttling.

所以，我有三個問題：

第一：爲什麼「壞CPU MHZ值= 0，RES ='CPU MHZ = 0「？我確切地說，所有核心的CPU節制設置爲0（我檢查了/ sys/devices/system/cpu/cpu */cpufreq/throttle文件）。有沒有辦法將ARM cpu的時鐘頻率作爲參數傳遞？

第二：爲什麼「sh：語法錯誤：EOF反向引用替換」？

第三：「無法找到可用的ICC編譯器; abortingMake ..」有沒有辦法說./configure可執行文件不尋找ICC？因爲我試圖在ARM上構建ATLAS，所以ICC不可用。

在此先感謝您的幫助！

ATLAS的配置環境打破了ARM，一般不是很容錯：

• 首先它試圖通過在/ proc/cpuinfo中grepping（它從不以確定系統性能除了一些人類可讀的信息轉儲之外，它們都是用於其他目的的）你可以通過在configure命令行中指定一個頻率來覆蓋它：-m <MHz>
• 然後它探測電源管理是否被啓用 - 如果是，它會再次釋放。看不到配置選項，但如果您在CONFIG/src/backend/archinfo_linux.c中使ProbeThrottle()返回0，則它會超過該選項。
• 幾年前，某些Cortex-A8平臺似乎已經完成了一些工作，CONFIG/src/atlcomp.txt中的默認設置爲ARMv7的編譯器標誌包括-mfloat-abi=softfp，這時您會遇到這種情況。將其更改爲「硬」，實際上它將用於現代ARM Linux發行版。
• 語法錯誤是由於試圖在/opt/bin和/opt/sbin中查找編譯器而不處理錯誤而產生的。

通過上述解決方法，我沒有看到任何ICC錯誤，並且在崩潰和刻錄之前構建得到了一個相當的位。

總之，爲了在ARM上正常工作，需要一些移植工作。也許你可以先發送錯誤報告給他們的開發者郵件列表？
