Adding Eigen library to Dev-C. Click add and ok then try to compile your program. It should now be able to find the files and build / run your program. An object library compiles source files but does not archive or link their object files into a library. Instead other targets created by addlibrary or addexecutable may reference the objects using an expression of the form $ as a source, where objlib is the object library name. If you have latest version of Dev-C, that ships with MinGW-w64 (as its native environment), then you may download pre-builded package of GMP from here. After that all you have to do is: Create simple C console project. Here is some basic main.cpp file. 1) downloading gsl-1.8-src.exe 2) Open Dev C and create a new project 3) Click Project-Project Options menu 4) Goto Directories tab 5) Goto 'Include Directories' sub-tab 6) Enter C: Program Files GnuWin32 include and press Add button 7) Goto Parameters tab 8) Click on button 'Add library or object' 9) Navigate and select C: Program Files. Without further ado, here is the step-by-step process for adding an external C library to your project using the CodeLite IDE. Note that this process will be different if you are using another IDE for C, but the two basic steps are the same: Add the path for the header files; Add the path for the actual code (i.e. The library).
in general even if there are no results for your specific case, you first need to know if the library works with your compiler, and if the library is NOT a headers only library, you also may need to compile the library for your specific compiler using a build system like Cmake or ninja or makefile or one of the many other build systems the library may offer. If you are very lucky you could have prebuilt binaries for the a very specific compiler version, but C++ isn't nearly as easily to link to a prebuilt binary as a prebuilt C library (if it is a C library congrats, it is very easy to link to a premade binary! usually), and being able to compile libraries from source will prepare you for writing cross platform code in the future, easily change compilers at need, and will give you a better understanding of how the C++ compiler works, which can help if you ever get into a real tricky build problem in the future.
In general for linking a project in a GCC comand line format (and probably similarish to how VS does it I imagine, but don't take my word for it) there are 3 parts:
1: include directories.
-I in the compile step, after the -O, usually libraries will just have a folder called 'include' (not always), it contains header files, this is all you need for header only libraries. This allows you to use libraries with #include <library.h> , but note there is no difference between ' and <> other than common use of signifying if a header is a library or not.2: linker directories.
-L when you call the linking step, in the command line this step requires you to compile a project using more than 1 raw command which is the last step called linking, this folder is usually called 'lib' or 'lib/x64|x86', (also note that there are no rules, sometimes small libraries put the linker files and the binary DLL into the same folder which is called 'win64/32', 'obj', 'bin' or something), this doesn't do anything without the 3rd and last step for specifically linker flags, similar how include directories don't do anything unless you #include the header. 3: linker flags (or if you want to skip part 2, you can manually link directly to the linker file, but should be avoided when possible). These are flags with a
-l in the linker step. These flags are connected to the names of .a for GCC or .lib for VS/clang, but the file extension is cut off, so 'freetype.a' would be '-lfreetype'.something to note is that this system makes dynamic libraries (DLL's) and static libraries (no DLL's) transparent, and it just depends on how the library was compiled on whether you need a DLL or not.
there is also an extra way of using libraries, which is the naive way (I wouldn't call it a library I would just call it a piece of code). which is to just include the headers and cpp files directly into your project that you are using.
You also aren't gonna get any help from us with such little effort put in your question.
If you still have problems give us every single thread of information you can, and give us your compile commands, your compiler version, open your project in CMD and tell us what the 'tree' command tells us, where the library is located, where you downloaded the library, write a demo that only uses 2 files which pretty much does hello world, and try to reproduce the problem and if it worked, then start adding things into it piece by piece until it stops working. You should try to solve the problem yourself before you get to us.
I would also argue that my experience with mingw wasn't without suffering, I had fun with the difficulty, but if you want something easier to work with, Visual Studios just looks easier, because in many cases where you are dealt with 'your only option is Cmake and something else you never heard of', you could search github and you will find someone who generated the solution files for VS and the specific version for you (and of course, pre-built binaries), but for mingw you aren't that lucky, or plain out 'this code is cross platform, buuuuuuuuut for windows we use VS and nothing else, because mingw is not an industry standard and its extra maintenance'. But I don't blame them since it is true that mingw has trivial flaws like with debugging core dumps, and the lack of the windows C runtime debug library (AKA memleaks and undefined behavior on windows), which are deal breakers.
Jun 14, 2011 2) under 'Linker', where it says: 'Add Library or Object', click that button, 3) scan across the list until you find the library you want to link, (.if libcurl.a is not in the default /lib/ folder, then select the correct folder), Double click on it, that will place libcurl.a in the linker list, repeat process.
C++ Syntax
Let's break up the following code to understand it better:
Example
using namespace std;
int main() {
cout << 'Hello World!';
return 0;
}

Run example »Example explained
Line 1:#include <iostream> is a header file library that lets us work with input and output objects, such as cout (used in line 5). Header files add functionality to C++ programs.
Line 2:using namespace std means that we can use names for objects and variables from the standard library.
Don't worry if you don't understand how #include <iostream> and using namespace std works. Just think of it as something that (almost) always appears in your program.
Line 3: A blank line. C++ ignores white space.
Line 4: Another thing that always appear in a C++ program, is int main(). This is called a function. Any code inside its curly brackets {} will be executed.
Line 5:cout (pronounced 'see-out') is an object used together with the insertion operator (<<) to output/print text. In our example it will output 'Hello World'.
Note: Every C++ statement ends with a semicolon ;.
Note: The body of int main() could also been written as:int main () { cout << 'Hello World! '; return 0; }

Remember: The compiler ignores white spaces. However, multiple lines makes the code more readable.
Line 6:return 0 ends the main function.
Line 7: Do not forget to add the closing curly bracket } to actually end the main function.
Omitting Namespace
You might see some C++ programs that runs without the standard namespace library. The using namespace std line can be omitted and replaced with the std keyword, followed by the :: operator for some objects:
Example
int main() {
std::cout << 'Hello World!';
return 0;
}

It is up to you if you want to include the standard namespace library or not.
