[Dev-C++] add to lib

[Wobien <wo...@pl...>]

Hello,
I made some functions and classes I want to reuse in other projects.

I can add the directory with the header files to the include directories and
that works fine.
I also have some .cpp files. It works if I add their object files to the new
project, but then I have to add all the object files one by one to each new
project.

It does not work if I add the directory with the object files to the library
directories.
Probably I need to make files with extention .a or .lib, but how do I do
that?

How can I make a real new library directory?

You need the archiver (ar.exe) tool. Read the attachments carefully! (or 
your gcc documentation :)

But I think dev-cpp can 'compile' things into libraries, you just need 
to set the project to "library".

Libraries are better than .o (object) files, because when you link from 
a library, only those functions are put into the exe, which are needed. 
If you link an object file to an exe, the whole stuff will be linked 
into it, even if you don't use all the functions from the object file.

I think it would be best for you to create a Library project with those 
files, and use the compiled library in your programs.

I hope that helps.

  Dev has the option for make a library, if you have the beta 5.
If not the process is this:
1- gcc -c for each source file.
2- ar -cru libname.a object files.
3- ar -s libname.a

You can have them in one directory and after the second step copy the 
library to the lib directory of dev, or any directory for libs of your 
own and then make the ar -s on its new location
