【中文标题】使用 qt creator 和 eigen 库编译程序时出现 lnk2019 错误【英文标题】：getting lnk2019 error when compile a program using qt creator and eigen library 【发布时间】：2018-10-10 06:26:03 【问题描述】：

我尝试在 qt 中编译一个项目，在我链接必要的库之后，我得到了休闲链接错误：

labelbox.obj:-1: error: LNK2019: unresolved external symbol "public: void __thiscall LabelImage::setAxis(class Eigen::Matrix<double,4,4,0,4,4>)" (?setAxis@LabelImage@@QAEXV?$Matrix@N$03$03$0A@$03$03@Eigen@@@Z) referenced in function "public: void __thiscall ImageView::setRotMat(class Eigen::Matrix<double,4,4,0,4,4> &)" (?setRotMat@ImageView@@QAEXAAV?$Matrix@N$03$03$0A@$03$03@Eigen@@@Z)

如果我从 eigen 进入 matrix.h，我会看到下一个问题： 在下面的代码行中：

 template<typename _Scalar, int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>
class Matrix
  : public PlainObjectBase<Matrix<_Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols> >

  * \c MatrixSizeType where \c Size can be \c 2,\c 3,\c 4 for fixed size square matrices or \c X for dynamic size,

  *
  * For example, \c Matrix3d is a fixed-size 3x3 matrix type of doubles, and \c MatrixXf is a dynamic-size matrix of floats.

  * There are also \c VectorSizeType and \c RowVectorSizeType which are self-explanatory. For example, \c Vector4cf is

【参考方案1】：

我不使用 qt，因此请谨慎对待。我看到您有两个可能的问题：

    在HEADERS += \ .... Dependencies/build_dir/include/eigen3/Eigen/src/Core/Matrix.h \ 我认为你应该改用Dependencies/build_dir/include/eigen3/Eigen/Core。 线路：INCLUDEPATH += $$PWD/Dependencies/eigen-eigen DEPENDPATH += $$PWD/Dependencies/eigen-eigen 似乎具有与上述“1”项中包含的路径不同的路径。如果两个目录相同，这可能不是问题，但如果不是，则会出现版本不匹配问题。
