在Beagleboard上编译-在AR上失败

Question

我正在Beagleboard-Xm上编译，内核：

root@beagleboard:~# uname -a
Linux beagleboard 2.6.32 #3 PREEMPT Tue Jul 26 10:56:56 CEST 2011 armv7l unknown

我现在尝试用CMake编译一个静态库，一切都很好，直到涉及到库的链接：

root@beagleboard:/usr/src/build/beaglebuild# make

BusyBox v1.13.2 (2011-02-25 16:46:47 CET) multi-call binary

Usage: ar [-o] [-v] [-p] [-t] [-x] ARCHIVE FILES

Extract or list FILES from an ar archive

Options:
    -o  Preserve original dates
    -p  Extract to stdout
    -t  List
    -x  Extract
    -v  Verbose

make[2]: *** [00_phoenix_base/libphoenix_base.a] Error 1
make[1]: *** [00_phoenix_base/CMakeFiles/phoenix_base.dir/all] Error 2
make: *** [all] Error 2

在我的"ar --help“中打印了同样的东西。

有没有办法让链接在电路板上运行？可能的问题是什么？

其他一些系统版本：

root@beagleboard:~# cmake --version
cmake version 2.8.2
root@beagleboard:~# g++ --version
g++ (GCC) 4.3.3

在经历了许多麻烦之后，我交叉编译了一个完全最新的ar版本(我认为板上的那个已经过时了)，并且我摆脱了BusyBox。

现在一切都和我预期的一样了。
