make in Ubuntu error,I went to 99 percent but failed about g2opy

[koide3]

I encountered the same problem on Ubuntu 20.04. In my case, I could build the library by changing:

        .def("x", (double (Eigen::Quaterniond::*) () const) &Eigen::Quaterniond::x)
        .def("y", (double (Eigen::Quaterniond::*) () const) &Eigen::Quaterniond::y)
        .def("z", (double (Eigen::Quaterniond::*) () const) &Eigen::Quaterniond::z)
        .def("w", (double (Eigen::Quaterniond::*) () const) &Eigen::Quaterniond::w)

in g2opy/python/core/eigen_types.h to:

        .def("x", [](const Eigen::Quaterniond& q) { return q.x(); })
        .def("y", [](const Eigen::Quaterniond& q) { return q.y(); })
        .def("z", [](const Eigen::Quaterniond& q) { return q.z(); })
        .def("w", [](const Eigen::Quaterniond& q) { return q.w(); })

Same here

Same here

I successly install g2opy in ubuntu 18.0 and python 3.8,you can replace your eigen3 by legacy version(eigen 3.4.4)，good luck for you

@1761865308 , Thank you so much! I will try it right away!

[ValeriiaIZH]

I still have the same error.
ubuntu 18.04, python 3.8, eigen 3.3.4-4.

I have the same issue.

@1761865308 , Thank you so much! I will try it right away!

I have same issue. Did you find solution ?

[Ali007788]

I still have the same problem!
ubuntu 20.4, python 3.8.10 and eigen 3.3.7
Has anyone an idea how to solve it?

@Ali007788

Try the koide3's solution - it has just worked for me.

[Ali007788]

@Twenkid
I already tried it, but the building went to 99% then I got this #58!
any tips?

[Twenkid]

Maybe out of memory error?
Try: make -j3 -B
Or -j1 (number of threads, -B -rebuild, -d debug;)
Watch the RAM usage with htop.

BTW, that combination "make -j8" is often given by default, but sometimes it is too much - for virtual machines etc. and there are no notes about that in the building instructions.

Follow koide3's solution and downgrade my python from 3.11 to 3.9 works for me
