问题


I try to compile a project in qt and after i link the necessary libs i ghet the fallowing linking error :

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)

If i go in the matrix.h from eigen i see the next problems : In the fallowing lines of code :

回答1:


I don't use qt, so take this with a grain of salt. You have two possible issues that I see:

  1. In the
    HEADERS += \ .... Dependencies/build_dir/include/eigen3/Eigen/src/Core/Matrix.h \
    I think you shoud be using Dependencies/build_dir/include/eigen3/Eigen/Core instead.
  2. The lines:
    INCLUDEPATH += $$PWD/Dependencies/eigen-eigen DEPENDPATH += $$PWD/Dependencies/eigen-eigen
    seem to have a different path than the included path in item '1' above. This may not be an issue if the two directories are identical, but if not, you'll have version mismatch issues.
