Problem in Dockerfile with installation of library

[DragonOsman]

I'm trying to build a Dockerfile for the project I've been working on that uses this library. The Dockerfile build output can be seen on this Paste: https://pastebin.com/hT1Ha6Lc . Could someone please tell me what I did and what I didn't do that I should've done? If needed, I'll also post the main part the problem is at:

Step 8/12 : RUN g++ -std=c++14 -Wall -pedantic -I app/jinja2cpp/install/include -I app/json/include -I app/json/single_include -I /usr/local/include/ -I app/jinja2cpp/thirdparty/nonstd/value-ptr-lite/include currency_converter.cpp -L app/jinja2cpp/install/lib/static -ljinja2cpp -L usr/local/lib/stage/lib/ -lboost_system -lpthread -o currency_converter
 ---> Running in bfb27a00d9c8
currency_converter.cpp:29:10: fatal error: nlohmann/json.hpp: No such file or directory
 #include <nlohmann/json.hpp>
          ^~~~~~~~~~~~~~~~~~~
compilation terminated.

Any help is appreciated. Thanks in advance.

Is this the same issue as #1296?

[nlohmann]

What is the content of directory app/json/include?

[DragonOsman]

I just ran this command to see what's in there:

RUN git clone https://github.com/nlohmann/json \
    && cd json \
    && cd include \
    && ls

Waiting for it to get to the ls part.

[DragonOsman]

Okay, directory named nlohmann confirmed to be inside directory include. Now I'll check if json is inside nlohmann. If it is, what do I do to fix that compiler error?

[nlohmann]

You provided both single_include and include. One is sufficient. Please see the README for integration information.

[DragonOsman]

What about when I want to use json_fwd.hpp, though?

[nlohmann]

Then just use include

Alright, thanks. I think this is solved now.
