How to use an already compiled library?

[cbun]

Hi, I'm new to Code:Blocks.
In my current C++ project I'm using a library (lib***.a) located with the header and source files in a certain folder.
I can compile and run my project but it does take ages to do so (over 2 min).
Instead of compiling just my file and using the library it does compile all of those files an shows a lot of warnings in those. It does this after each little change.
What did I miss?

Currently I'm using a newer version of the library. Before that I used an older version available in package sources of Ubuntu. But that needed an extra path as well.
Also had this Problem there. But somehow I managed it to work there (did also including restarting Code::Blocks).
Now I only get some short building time after building it once and dont change anything in code.



I did add the absolute folder path to:
- Project->Properties->C/C++ parser options
- Project->Properties->Debugger
- Project-> Build Options -> (select project name to the left) -> Search directories -> compiler
- Project-> Build Options -> (select project name to the left) -> Search directories -> linker
And did the path to the library itself:
- Project-> Build Options -> Compiler Settings -> Other resource compiler settings -> -l/pathto/libname.a
- Project-> Build Options -> Linker Settings


In console I can compile it with (in less than 5 sec):
g++ -o test ./main.cpp -L/pathtolibraryfolder/ -libname -I/pathtoheaderfolder_equalToLibfolder/

Post some build log

Thank you for response BlueHazzard.
Today somehow it took 'only' 40 sec.

I checked the build log. It included a lot of warning from my included headers (from that library).
After changing '-Weverything' to '-Wall' in build options it did only show warnings for my file.
After changing this building took only 2 sec.

with this build log is:

Yes, codeblocks has some problems with warnings, at least on windows...

It is not a windows only problem.
