在suse 10.1编译程序时出现的错误

我在编译 ex11.cpp （ which will be given at the end）的时候，使用编译命令
./a11 （whose content will be given later）会出一堆的错误，但是使用 a12 （最后给出）不会出错。
二者的差别是
tlu@linux-1482:~/proj/mpi/epetra> diff a12 a11
a11
< -lblas
< -lcblas
a12
> -lblas -lcblas

看在作编译命令的时候， -lblas -lcblas 在 SUSE linux 下要写在一起。

这样的事情在 Fedora Core 6 的机器没有出现。

a11 把分成两行写出现的错误如下：
