I am using Eclipse CDT on windows 7 64 bit and trying to work on Image Class using Image Magick but I am getting the below error-

I have added includes file to compiler and Library files in the linker in Eclipse. The library file in Image magick installed folder look strange to me, as they are not '.dll' files. Please let me know if I am right and how do i rectify this.

I am trying to compile this github repository on a Raspberry Pi 4 running Ubuntu 18.04. The code is written on c++.
https://github.com/unicorn-bi/Unicorn-Suite-Hybrid-Black/tree/master/Unicorn%20Raspberry%20Pi%20Zero%20W%20C%20API/UnicornCAPIAcquisitionExample
When I run the following line as in the example:
g++ main.cpp -I ../Lib -L ../Lib -lunicorn -o UnicornAcquisitionExample
I get the following error:
/usr/bin/ld: skipping incompatible ../Lib/libunicorn.so when searching for -lunicorn
/usr/bin/ld: cannot find -lunicorn
collect2: error: ld returned 1 exit status
It seems the shared library file is not compatible. This is weird since it should run also on the Raspberry Pi 4. I have tried to replicate the shared library file and I have tried to compile it also without it. I get always the following error:
/tmp/ccrr59RO.o: In function 'main':

main.cpp:(.text+0x6fc): undefined reference to 'UNICORN_CloseDevice'
collect2: error: ld returned 1 exit status
I am not sure if I should try to replicate the shared library file or doing without it but in either case I get always the following error. How can I compile the example in the github on the Raspberry Pi 4?
I am fairly new to Fortran and this may sound like a silly question. I encounter an error when compiling the Fortran code that is posted as an example in the NLOPT Wiki.
I compile in Ubuntu 18.04 LTS using the following command:
gfortran example-nlopt.f90 -o example-nlopt -I/usr/local/include/
The following error is produced in the terminal:

Based on what I saw in nlopt's documentation (https://nlopt.readthedocs.io/en/latest/NLopt_Installation/#changing-the-installation-directory) it looks like you just need to specify the library to link against. Maybe try this:
gfortran -I/usr/local/include/ -L/usr/local/lib example-nlopt.f90 -o example-nlopt -lnlopt -lm
This assumes you have the libnlopt.so in /usr/local/lib, if not then point to its location with the -L option.
Overview
I am attempting to convert a C++ project from a Visual Studio solution to a makefile project (using g++), as a first step to supporting multiple platforms with ease. This project requires the Simple DirectMedia Layer 2 (SDL2) and SDL_image libraries. The project previously compiled without errors, and I have since corrected any errors halting the g++ compiler. I am still using Windows x64 and MinGW x64 at this point.
Problem
When linking, g++ throws errors as though there is something wrong with the SDL2 library, claiming that all functions of SDL2 can't be found. However, I know it is finding the libraries, because when I provide an incorrect name or path, I get an explicit error.
Here is my new makefile, apologies if it isn't up to standard:
# Source files
SRC_ENTITIES = Entity_Block.cpp Entity_Controller.cpp Entity_Cursor.cpp Entity_GreenEye.cpp Entity_Harry.cpp

Troubleshooting
I have tried a number of things from supplying exact paths to libraries to updating SDL from 2.0.3 to 2.0.4. The behavior is the same. There are two include/lib folders in the MinGW devel folder for each architecture, and changing which one I include does not make a difference.
There seems to be a lot of commotion about the order of which arguments are supplied to g++, given the three posts below:
SDL2 Undefined references to functions
Try to change the sequence of the input params:
I've stumbled over this before (on Linux)
https://askubuntu.com/questions/68922/cant-compile-program-that-uses-sdl-after-upgrade-to-11-10-undefined-reference
Ok, solved. Apparently, for some mysterious reason, the order of the gcc options now matters.
http://smf.cataclysmdda.com/index.php?topic=11028.0
It looks like the SDL2_image library is included, but the main SDL2 library is not (the references could be out of order).
Unfortunately, regardless of how I have reordered the arguments, I can't seem to change this result. Unlike with most issues, I haven't even been able to make it any worse! Any and all help is greatly appreciated.
I don't believe this has anything to do with my code, considering a compile without linking -c completes fine, but if it assists with the solution I would be more than happy to post some of it (it is a LOT of code).
Edits
Per request, here is a dump of the full compile with the -v and -Wall options. It is too large for this question so I threw it in a pastebin.

Thanks to suggestions from #J.JHakala and #user657267 I have reached the conclusion that my installation of MinGW is actually 32 bit! Given that I was using the 64 bit libraries, they would read in like any other library, but the functions within them were not recognized.
For anyone else having this problem, you can download the 64 bit version of MinGW or alternatively just switch which libraries you are importing.

I tried to use libgraph library on ubuntu to use "graphics.h" for a sample program .
But while compiling i get these errors :

Do I need to add any more linker flags ? This program works on windows so I think the program itself is right .
I managed to get it run but the window crashes giving :
process_responses: Assertion `(((long) (dpy->last_request_read) - (long) (dpy->request)) <= 0)' failed.
also can I resize the window to full screen ?? thankx!
The installation instructions for libgraph seem a bit... casual. Chances are the library should just be explicitly linked in:
g++ graph.cpp -o graph /path/to/libgraph.a
or wherever it was installed.
Another possibility to investigate what library g++ uses:
g++ -print-file-name=graph
though on my system, it just echoes graph.
I have a simple openGL D program that compiles, but I can't get it to link with libglut.a. I've tried a few different command lines:

Is there a problem with my command lines, or is it something else?
Those look like mangled symbols from D code. You mentioned on your previous question that you were using some kind of compatibility layer – did you make sure to include the files or libraries from that in your build?
