标签： c++ compilation armadillo

我对编程很新。我已经使用随库提供的安装文件中的安装说明安装了armadillo库。

我使用以下命令安装了cmake LAPACK和BLAS 

sudo apt-get install cmake
sudo apt-get install liblapack-dev
sudo apt-get install libblas-dev

之后我使用以下命令安装

cmake .
make 
sudo make install

然后在编译示例程序后我收到此错误

g++ example1.cpp -o example1 -O2 -larmadillo -llapack -lblas

解决

我的主目录中安装了anaconda库。因此，cmake正在检测该文件夹中的intel MKL和其他库。我已更新我的LD_LIBRARY_PATH变量以包含该文件夹，问题已解决。

如果您在文件夹

中安装了anaconda，只需将以下行添加到/.bashrc即可 
text = "abcdef"
for idx,c in enumerate(text):        
    print(idx,c)
