Build Error - "No rule to make target . . . "

[Callahan-Henry]

When I attempt to run the build.sh script, I get the following error: "***No rule to make target ‘NR_SLAM/third_party/g2o/lib/libg2o_core.so’ needed by ‘lib/libNR-SLAM_d.so’. Stop.”. I can't seem to figure out how to resolve this issue. Any help would be greatly appreciated, thanks!

I am also struggling with that. My code doesn't compile properly, and I don't know how to fix it.

I got it！
‘NR_SLAM/third_party/g2o/lib/libg2o_core.so’ is generated when CMAKE_BUILD_TYPE is RELEASE.
As known in ‘g2o/CMakeLists.txt’:

But in 'NR-SLAM/CMakeLists.txt', CMAKE_BUILD_TYPE is set to DEBUG so that we can change it to RELEASE

Is there Docker Image about this ?
