I am trying to build TheiaSfM.
I build it with this command
cmake -DBUILD_DOCUMENTATION=ON -DEIGEN_INCLUDE_DIR=$EIGEN_INCLUDE_DIR ..
where I set EIGEN_INCLUDE_DIR=/usr/local/Cellar/eigen/3.2.9/include/
. This is the path to Eigen
in my computer.
But I got this error:
CMake Error at cmake/FindEigen.cmake:77 (message):
Failed to find Eigen - Could not find file:
/usr/local/Cellar/eigen/3.2.9/include/Eigen/src/Core/util/Macros.h
containing version information in Eigen install located at:
/usr/local/Cellar/eigen/3.2.9/include.
Call Stack (most recent call first):
cmake/FindEigen.cmake:123 (eigen_report_not_found)
CMakeLists.txt:108 (find_package)
I guess this is trivial, but I already tried to search but cannot really understand the problem. I am really new to this, so, any help would be really appreciated.
According to your error message, your program cannot find where the dir "Eigen" is. I guess it is in
/usr/local/Cellar/eigen/3.2.9/
Have you looked if there really is a sub-dir "include" in the above path? Official source code does not have this sub-dir.
So now you find that the dir Eigen
is in
/usr/local/Cellar/eigen/3.2.9/include/eigen3
As for the version issue, you could go to Eigen's website and download the desired version.
