1. gtsam install: git checkout tags/4.0.2 ;

Error： /Open3DGen/src/texture_projector.cpp:403:10: error: ‘atomic_int’ is not a member of ‘std’ 403 | std::atomic_int success_count = 0; Fix：texture_projector.cpp，加入#include <std::atomic_int>

Error： /usr/local/include/gtsam/base/Vector.h:76:30: error: static assertion failed: Error: GTSAM was built against a different version of Eigen 76 | GTSAM_EIGEN_VERSION_MAJOR==EIGEN_MAJOR_VERSION, Fix： Firstly cmake -DGTSAM_USE_SYSTEM_EIGEN=ON -DGTSAM_WITH_TBB=OFF .. ; but still get the error. So I decide to comment the code below in base/Vector.h

//static_assert( // GTSAM_EIGEN_VERSION_WORLD==EIGEN_WORLD_VERSION && // GTSAM_EIGEN_VERSION_MAJOR==EIGEN_MAJOR_VERSION, // "Error: GTSAM was built against a different version of Eigen");

2. open3D install Error： Open3DGen/src/math_modules.h:2:10: fatal error: Open3D/Open3D.h: No such file or directory 2 | #include <Open3D/Open3D.h> Fix： Because the version of open3D which install by libopen3d-dev on ubuntu 22.04 is 0.14.0. The structure has changed alot. So checkout to 0.9.0 and install with source code. git checkout tags/v0.9.0

Error： Open3D/3rdparty/pybind11/include/pybind11/pybind11.h:2036:30: error: invalid use of incomplete type ‘PyFrameObject’ {aka ‘struct _frame’} 2036 | frame->f_locals, PyTuple_GET_ITEM(frame->f_code->co_varnames, 0)); Fix： cmake .. -DBUILD_PYBIND11=OFF -DBUILD_CPP_EXAMPLES=OFF ，Because the version of python on ubuntu is not compatible with the pybind11.
