In Dev-C, click on the Tools menu and select the Environment Options menu option. Click on the tab labeled Files & Directories. Click on the small “folder selector” icon next to User’s Default Directory field. This will open a file dialog box that will let you navigate to and select your code directory.
@jianmingli1 the libraries you want (iostream, fstream etc.) come from the standard C library. There is no reason to add them, they are linked automatically. Just make sure you're creating a C project. If in doubt create a new C project from scratch and try.
Copy libgmp-10.dll shared library into Dev-Cpp MinGW64 bin; Edit properties of your project, add -lgmp flag into Linker (look for Parameters tab) Compile & Run; If you want other version or C interface, then you need to find existing build or try to compile it under MinGW environment.
I havn't used mingw before but from the looks of the download page, a lot of it is borrowed from cygwin anyway. I suggest if you want to learn about linux which is written in C/C download cygwin, if you just want an IDE that compiles with a click of the button use DEVCPP.
Select the 'Directories' tab, then the 'C Includes' tab. At the bottom-right of the panel, is an icon to click in order to browse to the directory where the Eigen files are located. In my case it was F: temp, click add and ok then try to compile your program. It should now be able to find the files and build / run your program.
How to install the C Boost Libraries on Windows. By Andres Jaimes. September 27, 2012. Boost is a set of high-quality libraries that speed up C development. They are included in most linux distributions and some of them are already part of the C Standard Library.

In Dev C,open the package manager: Tools-Package Manager. Here,you can see the pre-installed packages that came with your distribution of dev-cpp. To Install the glut package,click on Package-Install Package. Browse to the location where you’ve downloaded the glut devpak. Once you done with adding,it will appear in the package manager list.

Boost is a set of high-quality libraries that speed up C++ development. They are included in most linux distributions and some of them are already part of the C++ Standard Library. In the Windows environment, you have to install them in order to take advantage of them.

If you are using Microsoft Visual Studio, you can avoid the following steps by downloading a binary version from http://www.boostpro.com/download/ and skip to the Testing section in this document.

Before we start, you may want to read my previous article on installing a C++ compiler on Windows.

Installation

Download and unzip the boost source code from http://www.boost.org/. I will unzip it to C:optc-libs, but you can use the one you prefer. After you unzip, open a command line and go to your selected folder:

Start bootstrap.bat and specify your toolset. Toolsets supported by this script are: borland, como, gcc, gcc-nocygwin, intel-win32, metrowerks, mingw, msvc, vc7, vc8, vc9, vc10, vc11. In my case I will use the mingw toolset:

All required files for compilation should be ready. Now you have to define a installation directory and specify a toolset. Toolsets here are a little bit different from the ones we used before:

acc: Hewlett Packard, Only very recent versions are known to work well with Boost
borland: borland
como: Comeau Computing, Using this toolset may require configuring another toolset to act as its backend
darwin: Apple, Apple’s version of the GCC toolchain with support for Darwin and MacOS X features such as frameworks.
gcc: The Gnu Project, including Cygwin and MinGW
hp_cxx: Hewlett Packard, Targeted at the Tru64 operating system.
intel: Intel****
msvc: Microsoft
sun: Sun, Only very recent versions are known to work well with Boost.
vacpp: IBM, The VisualAge C++ compiler.

Since I’m using MinGW I will use gcc.

At this time you can go get a cup of coffee. Or maybe two.

When compilation ends, go to your selected installation path (watch out!, this is not the folder where you originally unzipped the source code). You will find two folders: include and lib. Both folders should contain files. That means you are done and ready for the testing phase.

If any of the afore mentioned folders is empty then we have problems. Common problems arise due to selecting the wrong toolset for compiling, so if your lib folder is empty try choosing a different toolset. If error persist, take a look at the compilation output. Errors must be shown there, specially at the last lines of the output.

Testing

From your IDE create a file named main.cpp and copy the following text onto it:

It’s time to compile (and link)

In order to let your compiler know where to look for the headers and libraries, you have to follow the next steps. You can usually accomplish them by right clicking on your project and selecting Properties or Options.

Add the following path to your includes list:

Add the following path to your additional library directories list

Important: if you are using Netbeans, you should only type /installation/path/lib (you have to omit the C:). For a very strange reason, Netbeans adds a forward slash at the beggining of the parameter /L used to compile (only when it begins with C:) resulting in an unknown path. This might be fixed in later versions.

If you are using a gnu compiler (that is Cygwin or MinGW), you must also add the specific library to the linker. If you are using Microsoft Visual Studio you can skip this step because it includes the so called auto-linking support. But, in my case, I have to add the following library to my libraries list so the linker performs without complaints:

This file name is composed by:

The standard lib prefix. DLL’s do not use it.
The library name boost_regex.
The toolset used to compile it, in my case mgw47, that is MinGW version 4.7.
The threading tag mt, which indicates if the library accepts multithreading.
The ABI tag, that can be: d for debugging, s for static linkage or g, y, p which are not covered in this text.
The version tag.
The extension, which can be .lib or .a.

You are ready. Build the program. mac dre full album download

Time to execute it

The program you just compiled (and linked) can parse a text file looking for a line starting with the text “Subject:” in it. So to test it, copy and paste the following text into an empty text file and name it test.txt (save it in the folder where your .exe file resides):

Now, from a command prompt type:

If everything goes right you should see the following text:

Conclusion

At this point, boost should be ready on your Windows computer. I suggest you read about this tremendous library since it can help you make your life a lot easier.
