Not on bitshares, on a testnet. I am trying to learn about the functionality.

I can not find the right parameters :-( I will try to lookup the web

The boost version is 61
#define BOOST_VERSION 106100
#define BOOST_LIB_VERSION "1_61"

I had to upgrade my debian machine to "stretch" to be able to install libboost (at sufficient level). (kernel: 4.6.4-1)
The compilation stops at :
libraries/fc/src/thread/thread.cpp:5:
libraries/fc/src/thread/context.hpp:215:9: error: ‘fcontext_t’ in namespace ‘bc’ does not name a type
     bc::fcontext_t               my_context;
         ^~~~~~~~~~

is this a know problem ? Do I need to change some libraries to compile the code ?

I did something else. I found on a different thread the resync command line option:

./programs/witness_node/witness_node –replay-blockchain --resync-blockchain

Now the node dose something

This is what I did

1. create a full node based on this: http://docs.bitshares.eu/integration/apps/node.html
2. modified almost nothing in config.ini (rpc-endpoint = 127.0.0.1:8090 ; logger.p2p: level=info)

I get this from the node:

I get this in the wallet:

Is this correct ?

after that it does nothing. Do I need to specify something else ? Adding a wittness ID does not change anything. I have no private key so I can not add it.
