How to integrate cregres in your code

With CMAKE

cd to the root directory and run cmake . && make

Without CMAKE

CREGRES code consists of several C source files and their corresponding headers. You can directly use these files in your code by including "cregres.h" header in your code.

gcc -Wall -c *.c 

will work with GNU gcc compiler. It will build object files of all the files in the /src folder and you can link your project against these object files. This is more straightforward if you are using one of the modern IDEs as you can just plug all the 54 files in your code and just link "cregres.h" to your project files. The IDE will do the rest. If you are an expert programmer then you may want to skip the rest of this section.

Building Shared and Static Libraries on Linux

A Simple Static Library

If you are using GNU GCC compiler then something like

gcc -c *.c

will build the object files in the src folder. You can then package the object files in a cregres.a static library package using

ar rcs libcregres.a *.o

A Simple Shared Library

    gcc -fPIC -c *.c
    gcc -shared -Wl,-soname,libcregres.so.1 -o libcregres.so.1.0   *.o

You may want to move libcregres.so.1.0 to a separate folder before creating symlinks.

ln -sf libcregres.so.1.0 libcregres.so
ln -sf libcregres.so.1.0 libcregres.so.1

If your folder is not on the path then you will have to export the path before executing your program.

export LD_LIBRARY_PATH=/cregresFOLDERLOCATION/

Building Shared and Static Libraries on Windows

Use IDE to build the libraries

I am mentioning this approach as most Windows programmers use one or more IDEs for their programming. All modern IDEs can create static and DLLs from source codes. eg., In Visual Studio you start out by creating an empty project, then adding all the source ad header files followed by "Build Solution".

It is equally straightforward to create libraries in Eclipse , Codeblocks and other IDEs.

Working with Cygwin

A Static library (.a) build is identical to that with linux.

A Simple Static Library

If you are using GNU GCC compiler then something like

gcc -c *.c

will build the object files in the src folder. You can then package the object files in a libcregres.a static library package using

ar rcs libcregres.a *.o

A Simple DLL in Cygwin

This will build a simple standalone DLL.

gcc -c -fPIC *.c
gcc -shared -o libcregres.dll *.o

Check this link for more options, specially if you want to build the DLL as an export library.

The File cregres.h from the header folder should be used with the library that you just build
