Eigen3從Linux Mint的17.3回購，稀疏矩陣未命名

我想在我的項目中使用Eigen3，當我嘗試使用CMake的構建，使Eigen3從Linux Mint的17.3回購，稀疏矩陣未命名

/usr/include/eigen3/unsupported/Eigen/src/KroneckerProduct/KroneckerTensorProduct.h:246:11: error: ‘SparseMatrix’ does not name a type 
     typedef SparseMatrix<Scalar, 0, StorageIndex> ReturnType;

我使用Linux Mint的17.3我得到這個錯誤。我有eigen2和eigen3庫，我很確定CMake正在挑選eigen3（尤其是考慮到我在上面發佈的錯誤消息）。我使用命令 sudo apt-get install libeigen3-dev安裝了eigen3。當我運行apt-cache show libeigen3-dev我得到

Description-en: lightweight C++ template library for linear algebra 
Eigen 3 is a lightweight C++ template library for vector and matrix math, 
a.k.a. linear algebra. 
. 
Unlike most other linear algebra libraries, Eigen 3 focuses on the simple 
mathematical needs of applications: games and other OpenGL apps, spreadsheets 
and other office apps, etc. Eigen 3 is dedicated to providing optimal speed 
with GCC. A lot of improvements since 2-nd version of Eigen.

這裏有一個最小的代碼片段：

#include <unsupported/Eigen/KroneckerProduct> 
int main() { 
    return 0; 
}

與g++ -std=c++11 -I /usr/local/include/eigen3 hello.cpp -o hello 編譯：

In file included from /usr/local/include/eigen3/unsupported/Eigen/KroneckerProduct:30:0, 
       from hello.cpp:4: 
/usr/local/include/eigen3/unsupported/Eigen/src/KroneckerProduct/KroneckerTensorProduct.h:246:11: error: ‘SparseMatrix’ does not name a type 
    typedef SparseMatrix<Scalar, 0, StorageIndex> ReturnType;

官方版本怎麼樣？ – kangshiyin

我測試了mercurial repo的官方版本，並且得到了同樣的錯誤。 – BlazePascal

舊版本如3.2.9如何？無論如何，它是'不支持的' – kangshiyin

您的問題可以用正確的inlcude s內解決。第一個定義了SparseMatrix，它糾正了你的第一個錯誤信息。第二個使用正確的路徑來糾正你的第二個錯誤信息。

#include <Eigen/Sparse> 
#include <unsupported/Eigen/KroneckerProduct> 
int main() { 
    return 0; 
}

這仍然給出了我最初列出的錯誤。 'SparseMatrix不會命名一個類型......' – BlazePascal

你如何配置你的代碼？什麼是編譯選項？ – kangshiyin

'g ++ -std = C++ 11 -I/usr/local/include/eigen3 hello.cpp -o hello' – BlazePascal
