I had a similar problem and added

#include<unistd.h>

into include/System.h before running

./build.sh

in ORB_SLAM2/.

As System.h is probably one of the first files to be called, adding the code will apply its modifications to all the other headers called within/after it.

If you still have this problem, add the include to all the .cc files mentioned in

CMakeFiles/<filedir/filename>make:159: recipe for target '<filedir/filename.cc>`

-like lines and retry

rm -rf build && ./build.sh

until you have no more files do modify !

thank you for you help! I have already added and I found that my Pangolin version is the latest version that maybe have some bug or mistake. So i change Pangolin to the old version and succeed "build.sh" . Thank you again!

I had these similar problems , and i had added "#include" in every .cc project, i also changed the version of my Pangolin to 0.5. The attempt of these methods did not solve my problem. What should I do?

I had the same problem!
