如何在Qt创建者项目中使用restclient-cpp？

Question

I'm working on my first QT project. I need to access a Rest API and decided to give https://github.com/mrtazz/restclient-cpp a try.

The issue is that i'm not able to make it work. I'm getting this error when building the project:

Undefined symbols for architecture x86_64:
  "RestClient::get(std::string const&)", referenced from:
      _main in main.o
ld: symbol(s) not found for architecture x86_64

I'm not sure if this is correct. But i downloaded restclient-cpp and curl into 3rdparty/libs folder.

After that, added the following code in my .pro file:

LIBS += -L"$$_PRO_FILE_PWD_/3rdparty/libs/"
INCLUDEPATH += "$$_PRO_FILE_PWD_/3rdparty/libs/"

In main.cpp I added:

#include <restclient-cpp/include/restclient.h>

And the error happens when i add the following line to my code:

RestClient::response r = RestClient::get("http://localhost/customers");

Without this line, at least I can build the project.

What's the right way to do this?

I compiled curl and restclient. Curl was compiled with a basic ./configure && make. Restclient was compiled with:

autoreconf -vif
./configure
make

Install curl( example ):

• install libcurl. open terminal and issue the command “sudo apt-get install curl” without the qoutes.
• the do this in your terminal again:
• “sudo apt-get install libcurl4-openssl-dev”
• “sudo apt-get install libcurl4-gnutls-dev”
• “sudo apt-get install libcurl4-nss-dev”

Insall restclient-cpp:

• ./autogen.sh
• ./configure
• make install

My .pro file example:

# Add restclient-cpp
LIBS += -L/usr/local/lib/ -lrestclient-cpp

And just add:

#include "restclient.h"
