我已尝试应用以下步骤将 Armadillo 库静态链接到 Visual Studio 2017 for C++,但无济于事。平台设置为 x64
- C/C++ -> 常规 -> 附加包含目录 -> $(SolutionDir)Dependencies\include
- 在源文件中编写
#include "armadillo"
(也尝试了 #include)。 - 链接器 -> 输入 -> 附加依赖项 -> blas_win64_MT.lib; lapack_win64_MT.lib
- 链接器 -> 常规 -> 附加库目录 -> $(SolutionDir)Dependencies\lib_win64
注意:
include is the name of a folder having armadillo and armadillo_bits folder in Step 1.
lib_win64 is the name of a folder having blas_win64_MT.lib and lapack_win64_MT.lib in Step 4
.
当我尝试编译时,遇到了以下错误:
c:\........\dependencies\include\armadillo_bits\arma_rng.hpp(444): error C2760: syntax error: unexpected token 'identifier', expected ';'
c:\........\dependencies\include\armadillo_bits\arma_rng.hpp(524): note: see reference to class template instantiation '
arma::arma_rng::randn<std::complex<_Other>>
' being compiled
.
arma_rng.hpp 的代码,直接来自 armadillo 库代码。
template<typename T>
struct arma_rng::randn < std::complex<T> >
{
inline
operator std::complex<T> () const
{
T a, b; //************line 444***************
arma_rng::randn<T>::dual_val(a, b);
return std::complex<T>(a, b);
}
inline
static
void
fill(std::complex<T>* mem, const uword N)
{
...
}; //************line 524***************
.
这是一个直接来自 Armadillo 示例的代码,用于测试我是否正确链接 Armadillo ,目前没有实现头文件:

最佳答案
请将您的 VS2017 平台工具集更改为 v140 而不是 v141。然后编译,一定可以。
