Can someone point what's the reason for this error?

/usr/include/boost/property_tree/detail/json_parser_read.hpp:257:264: error: ‘type name’ declared as function returning an array

Hi so did updating gcc work for you?

[jinuhjoo]

Update works! But there is a easier way to change your g++ version.
Instead of changing the link file of your g++ in /usr/bin/
Just change your makefile.config like this to fit your g++ version
i.e. CUSTOM_CXX := /usr/bin/g++-4.9

[MudeLin]

If you don't need to save result to json file, you could simply comment the json_parser header, and write_json.

I meet exactly the same error. I also find that blog, but I fail to update gcc using the same command as u. Errors are like below:

gph@gph-pc:~$ sudo apt-get install gcc-5

do u have any suggestion? thanks a lot!

easy workaround (sudo not required!):

in <caffe_root>/src/caffe/layers/detection_output_layer.cu and .cpp: search for write_json and comment it out

in <caffe_root>/include/caffe/layers/detection_output_layer.hpp:
//#include <boost/property_tree/json_parser.hpp>

and then
make clean
make -j8

as far as I know, write_json is only used to write results in VOC format ...
