error with boost

[nelkabosal]

In the final make, I'm getting a lot (probably a couple dozen) of undefined reference toboost::program_options::...` flags and the recipe for target 'offline_reconstruction' failed.

I thought perhaps it was an issue with boost, but when looking in the cmake ../src output, I do see

-- Boost version: 1.58.0
-- Found the following Boost libraries:
--   program_options
--   filesystem
--   system

Is there a minimum version for Boost? Or do I need to check elsewhere for the source of the errors?

I do have exactly the same version installed on my machine, this should not be an issue. What is your OS?

[nelkabosal]

My OS is Ubuntu 16.04

Also, I'm not sure if it makes a difference, but I am using gcc version 4.9.4

If it helps, here is my link.txt in CMakeFiles/offline_reconstruction.dir. If you see anything out of place, please let me know. I'm kind of stuck

I just re-read the whole thread. offline_reconstruction is not strictly necessary if you just want to play around with the GUI, you could deactivate the target in CMakeLists.txt

That being said, I have no idea why it compiles on my machine (which is also Ubuntu 16.04) and not on yours :(

[nelkabosal]

What does offline_reconstruction specifically do?

[reini1305]

Sorry, I missed that last post. 'offline_reconstruction' allows you to run the algorithm without a user interface to do automatic testing and evaluation.
