INSTALLATION

Dependencies:

• AMQP-CPP 4.3.10

  • Note that it MUST be linked with -Wl,--no-as-needed -ldl. Not sure why AMQP-CPP devs didn't include it
    • Easiest way to do this is changing the line in AMQP-CPP 4.4.10/src/Makefile
    • While in AMQP-CPP 4.3.10 you can run command:
    • sed -i "5 a LD_FLAGS = -Wall -shared -Wl,--no-as-needed -ldl" ./src/Makefile
    • Then you can install AMQP-CPP using make make -j8 && sudo make install && sudo ldconfig
  • If the library is linked incorrectly you will get a linker error in amqpcpp library while compiling your worker

• Boost, tested version 1.71

• ICU, tested version 66.1

Installation using deb file [Recomended]

Creating deb file

mkdir build && \
cd build && \
cmake .. && \
cmake --build . && \
cpack

Deb file installation

dpkg -i ./wsnlp-1.1.0-Linux.deb

Installation: [From orginal nlp-cpp]

mkdir build && \
cd build && \
cmake .. && \
make -j && \
sudo make install

USAGE

To create service you have to include header:

#include "nlpworker.h"

and implement class:

class your_Worker: public NLPWorker
{
 public:
 void process(string task_path, boost::property_tree::ptree &config, string output_path);
 void static_init(boost::property_tree::ptree config);
 void init(boost::property_tree::ptree config);
 };

add this main function to your file:

int main(int argc, char* argv[])
{
    run_workers<your_Worker>(argc,argv);
}

Now you can compile your code with linked -wsnlp library.

To run worker you need to place config .ini file. Below there is a template, fill it properly and if needed add your own section.

[service]
tool = name_of_your_worker
root = /samba/requests/
rabbit_host =
rabbit_user =
rabbit_password =

[tool]
workers_number = number_of_workers
