how do you instill a library?

[orion-]

i downloaded a math library from www.swox.com/gmp and i am not quite sure how to install it so i can use it in my applications. could someone tell me please? the compiler i am using is bloodshed dev-c++ (version 4.9.9.2). thank you.

well, its not so much an install process. Do you have the .lib file? that is all you need.
You drop it into your project folder.. or if you want it in multiple projects you could set dev c++ to use that file as a standard library or something.
But simplest way is to drop it in your project folder, then include it in your project, and in a header file of ur main file put this code

#pragma comment ( lib, "libraryname.lib" )

Thats all, then you can use the functions of the library in any page includeing the header file the pragma is in.

Have you read the manual? It is explained there how to install and use it.

#pragma comment ( lib, "libraryname.lib" )

I don't think it works in Dev-C++.
In project options, put "-llibraryname" to the linker parameters box.

btw. dev-c++ is not a compiler. dev-c++ is an IDE (it's just a graphical window where you can enter your code and process it and stuff like that). the compiler that comes with dev-c++ is gcc (I don't know the version of it).

You will need to compile GMP. If you are impatient, this can be done with the dance:

./configure
make
make check
make install

You will need MSYS, and might well just install MinGW too. The MinGW port of GCC is the default compiler in Dev-C++ 4.9.9.2.
