Hi @firelw , I met the same problem. The same code can detect tag in one computer but detects nothing in another. I fixed the issue by change the compile option in apriltag_mit/CMakeLists.txt:
change the code from:

set(CMAKE_CXX_FLAGS "-std=c++11 -Ofast")

to

set(CMAKE_CXX_FLAGS "-std=c++11")

I hope this can be helpful to your issue.
