If you look at Tesseract "compiling" page, you will find that the step-by-step instructions are started from Linux and are written primarily for this OS:

Thanks! Do I get a library if I compile the project? Or do I get a binary if I compile the project?

Sergey Alexandrovich Kryukov 5-Nov-13 14:18pm

I think you will. I haven't try to use Tesseract for a while, but when you compile a project, you will certainly get something "binary", a static library (a kind of object file) or shared library (a kind of executable file, basically, same thing as "DLL"). Usually, this is a choice you can make. But everything is "binary".
All right, will you accept the answer formally (green "Accept" button)?

Thanks! I did it, I compiled it, but i got a binary in /usr/local/bin. But I need it as a single-library only. I will open a new question.

Did you see *.so file(s) anywhere? It would be a shared library you could use.

There is a *.a - File containing all information, looks like a big library.

Sergey Alexandrovich Kryukov 14-Nov-13 12:37pm

This is a static library, *.a. It goes to the input of the linker. In contrast to that, *.so is a shared library, a sort of executable file, used in the same was as Windows DLL.
And *.a is object code, collection ("archive", hence "a") of executable code.

Do you know the basic C++ development cycle? Source code —> compiler —> object code —> +other object files +static (object) libraries —> linker —> executable code (including *.so shared libraries) —> loader —> application process. That would be the major part of the answer to your new question you plan to ask; you can reference my comment and ask what's not yet clear...
