My guess is that khronos and glog might have conflicting gflags versions. What's the output of `ldd /lib/libkhronos.so|grep glog` and `ldd /lib/libkhronos.so|grep gflag` for you?

Sorry, to clarify, I am suspecting that you might have duplicated glog installs on your system, hence was curious to see your ldd output and exactly what is being used....

Hi @LimHyungTae technically it should be automatically downloaded! Please see here. Though it is indeed a problem that it fails silently sometimes. https://github.com/MIT-SPARK/Kimera-Multi-LCD/blob/main/cmake/vocab_download.cmake

Has this issue been resolved? I would double check if the rosbags were downloaded and decompressed correctly.
