我要编译包含Armadillo库的C程序.
使用此命令通过命令行可以解决此问题：

g++ '/arm.cpp' -o example -O1 -larmadillo

但是当我将-O1 -larmadillo添加到我的NetBeans项目的编译选项时,我收到了大量的错误.

我收到了这些错误：

解决方法:

我知道这是一个老问题,但最近我遇到了麻烦,所以如果有人遇到和我一样的问题,我想帮忙.这是如何在64位Windows 7上的NetBeans C中设置Armadillo库.

>从http://arma.sourceforge.net/download.html下载最新版本的Armadillo
>在任何您想要的目录中将其解压缩.
>转到Netbeans – >项目属性 – > C编译器

3.1包括目录 – >找到您的Armadillo目录并选择文件夹“include”.

3.2预处理器定义 – > ARMA_USE_LAPACK ARMA_USE_BLAS
>转到Netbeans – >项目属性 – >链接

4.1附加图书馆目录 – >找到您的Armadillo目录并选择文件夹“examples / lib_win64”.

4.2附加依赖性 – > lapack_win64_MT.lib blas_win64_MT.lib
>转到项目的文件夹并添加Armadillo / examples / lib_win64中的文件.应添加4个文件 – > blas_win64_MT.dll,blas_win64_MT.lib,lapack_win64_MT.dll和lapack_win64_MT.lib.

这应该是它.现在你可以在C中使用Armadillo库,只需添加你的cpp #include,如果你想使用命名空间arma;

我希望这可以帮到你！干杯!
