在NeatBeans上使用Armadillo库编译c ++ [英] Compiling c++ with Armadillo library at NeatBeans
问题描述
我将编译包含Armadillo库的C ++程序. 通过使用以下命令在命令行中可以解决此问题:
I am going to compile C++ program which contains Armadillo library. This issue is feasible via command line with this command:
g++ '/arm.cpp' -o example -O1 -larmadillo
但是，当我在NetBeans项目的编译选项中添加-O1 -larmadillo时，会出现相当多的错误.
But when I add -O1 -larmadillo to the compile options of my NetBeans project I get a considerable amount of errors.
我遇到了这些错误:

推荐答案
我知道这是一个老问题，但是最近我遇到了麻烦，因此如果有人遇到与我相同的问题，我想提供帮助.这是在64位Windows 7上的NetBeans C ++中设置Armadillo库的方法.
I know this was an old question, but I had troubles recently with this so I want to help if someone else encounters same problems as I did. This is how-to setup Armadillo library in NetBeans C++ on 64 bit Windows 7.
将其解压缩到任何目录中.
Unpack it in some directory, where ever you want.
转到Netbeans->项目属性-> C ++编译器
Go to Netbeans -> Project Properties -> C++ Compiler
3.1包含目录->找到您的Armadillo目录，然后选择文件夹"include".
3.1 Include Directories -> find your Armadillo directory and select folder "include".
3.2预处理程序定义-> ARMA_USE_LAPACK ARMA_USE_BLAS
3.2 Preprocessor Definitions -> ARMA_USE_LAPACK ARMA_USE_BLAS
转到Netbeans->项目属性->链接器
Go to Netbeans -> Project Properties -> Linker
4.1其他库目录->找到您的Armadillo目录，然后选择文件夹"examples/lib_win64".
4.1 Additional Library Directories -> find your Armadillo directory and select folder "examples/lib_win64".
4.2其他依赖关系-> lapack_win64_MT.lib blas_win64_MT.lib
4.2 Additional Dependencies -> lapack_win64_MT.lib blas_win64_MT.lib
转到项目的文件夹，然后从Armadillo/examples/lib_win64添加文件.应该添加4个文件-> blas_win64_MT.dll，blas_win64_MT.lib，lapack_win64_MT.dll和lapack_win64_MT.lib.
Go to your project's folder and add files from Armadillo/examples/lib_win64. 4 files should be added -> blas_win64_MT.dll, blas_win64_MT.lib, lapack_win64_MT.dll and lapack_win64_MT.lib.
应该是这样.现在，您可以在C ++中使用Armadillo库，只需在cpp #include中添加，如果要使用名称空间arma;
This should be it. Now you can use Armadillo library in C++, just add in your cpp #include and if you want using namespace arma;
我希望这会有所帮助！干杯！
