Error installing a .pro file, with Eigen, libigl dependencies on Debian
问题
我正在尝试在Debian-9上使用'make'安装一个.pro文件。依赖项包括Qt5、GSL、libigl、Eigen和Boost，它们的最新版本已安装。
我使用了以下命令：
# cd build
# qmake -qt=qt5 ../qt/myfile.pro
# make
以下是我遇到的错误：
../libigl/include/igl/copyleft/boolean/../cgal/order_facets_around_edge.cpp:203:36: error: ‘Eigen::PlainObjectBase<Derived>::PlainObjectBase() [with Derived = Eigen::Matrix<int, -1, 1>]’ is protected within this context

请问是否有人可以帮助我解决这个问题？

Could someone please kindly help me solving the issue here?

这一行：
Eigen::PlainObjectBase<DerivedI> positive_order, negative_order;
无法编译通过。它可能曾经可以编译通过旧版本的Eigen，但这不是Eigen-Base类型的正确用法，因此它很可能从未按照预期工作过（这也是为什么在Eigen中将Base构造函数设为受保护的原因）。
然而，在最新的 order_facets_around_edge.cpp 中不存在这行代码，所以您似乎正在使用一个过时的libigl版本。
英文:
This line
Eigen::PlainObjectBase<DerivedI> positive_order, negative_order;
won't compile. It may have once compiled for older Eigen versions -- but this is not how Eigen-Base types are supposed to be used, so it likely was never working as intended (that is also the reason why Base-constructors where made protected in Eigen).
However, that line does not exist in the most recent order_facets_around_edge.cpp, so you appear to be using an outdated libigl version.
