Sophus cant build

[PsouthRobotics1182]

If i checkout Sophus commit a621ff, and try to build with make i get this error

`usr/bin/cmake -H/home/drew/svo/workspace/Sophus -B/home/drew/svo/workspace/Sophus/build --check-build-system CMakeFiles/Makefile.cmake 0

and if I use a later version of sophus which doesnt have this problem i get this error when using 'catkin make' at the end to build rpg-svo

it cant find the header because it doesnt exist in the latest version, but in older versions it has errors. What todo?

[ahmadyan]

It is a known issue with that commit. Try replacing that line with

unit_complex_ = std::complex<double>(1,0);

unit_complex_ = std::complex<double>(1,0);

That's fix my problem!

Thank you!
