2 years ago Sorry, I cannot reproduce this on my machine (and travis is not longer functional for me to test it on other machines...) Some recommendations:
- I'm working on a v2.0 of dmpbbo, where the C++ code has been simplified greatly: https://github.com/stulp/dmpbbo/tree/v2 If you are starting with dmpbbo "from scratch", I highly recommend working with this version instead. It will be the new release in a few weeks.
- If you really need the old API, I recommend trying https://github.com/stulp/dmpbbo/tree/v1.0.0, where json was not used yet. This may avoid the compilation error above (which is related to json I/O)
Hey bro! Something went wrong when I compiled the code. The compilation process is as follows：
