ATLAS on ARM配置失败

Question

我试图在我的Tegra3 ARM CPU（cortex-a9）上安装Ubuntu 11.04操作系统下的ATLAS库（v3.10.1），但是我无法通过配置步骤.. 当我启动该 “的./configure” 可执行我得到这个输出如下：

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，我有三个问题：

第一：为什么“坏CPU MHZ值= 0，RES ='CPU MHZ = 0“？我确切地说，所有核心的CPU节制设置为0（我检查了/ sys/devices/system/cpu/cpu */cpufreq/throttle文件）。有没有办法将ARM cpu的时钟频率作为参数传递？

第二：为什么“sh：语法错误：EOF反向引用替换”？

第三：“无法找到可用的ICC编译器; abortingMake ..”有没有办法说./configure可执行文件不寻找ICC？因为我试图在ARM上构建ATLAS，所以ICC不可用。

在此先感谢您的帮助！

ATLAS的配置环境打破了ARM，一般不是很容错：

• 首先它试图通过在/ proc/cpuinfo中grepping（它从不以确定系统性能除了一些人类可读的信息转储之外，它们都是用于其他目的的）你可以通过在configure命令行中指定一个频率来覆盖它：-m <MHz>
• 然后它探测电源管理是否被启用 - 如果是，它会再次释放。看不到配置选项，但如果您在CONFIG/src/backend/archinfo_linux.c中使ProbeThrottle()返回0，则它会超过该选项。
• 几年前，某些Cortex-A8平台似乎已经完成了一些工作，CONFIG/src/atlcomp.txt中的默认设置为ARMv7的编译器标志包括-mfloat-abi=softfp，这时您会遇到这种情况。将其更改为“硬”，实际上它将用于现代ARM Linux发行版。
• 语法错误是由于试图在/opt/bin和/opt/sbin中查找编译器而不处理错误而产生的。

通过上述解决方法，我没有看到任何ICC错误，并且在崩溃和刻录之前构建得到了一个相当的位。

总之，为了在ARM上正常工作，需要一些移植工作。也许你可以先发送错误报告给他们的开发者邮件列表？
