[poppler] Linking Poppler to Code::Blocks

2013-04-21 Thread Christopher Icely

Good Day All,

Firstly, I do apologize if this is the incorrect forum in which to ask my
questions however, I'm really at my wit's end with this problem and I was
hoping one of you could perhaps help me.

Basically I wish to write code that will allow me to extract annotations
from PDFs. However, I'm yet to write any code as I've spent an inordinate
amount of time in just getting Poppler built. These are the steps I've
followed so far:

{System specs: Windows 7, MinGW, CodeBlocks}

1) I have a folder structure like so:
C:\Users\Chris\Documents\Poppler\build\
-poppler-0.22.2
-poppler-0.22.2_Build

The file poppler-0.22.2 is the unzipped source files while the
poppler-0.22.2_Build file was made by the Cmake GUI with Cairo, JPEG, QT4
and TIFF included. Furthermore, Cmake was instructed to generate a
CodeBlocks - MinGW Makefiles.

2) After the CodeBlocks project was generated by Cmake, the project was
built in CodeBlocks and I was left with the following:

C:\Users\Chris\Documents\Poppler\build\poppler-0.22.2_Build\
--CMakeFiles
--cpp
--poppler
--qt4
--test
--utils
--cmake_install.cmake
--CMakeCache
--config.h
--CTestfile.cmake
--libpoppler.dll
--libpoppler.dll.a
--Makefile
--poppler.cbp
--poppler.layout

3) Now i need to link the poppler library to my project. Therefore in
CodeBlocks I did the following:

a)Settings-Compiler-Linker settings: Link libraries
and I set the path to:
C:\Users\Chris\Documents\Poppler\build\poppler-0.22.2_Build\libpoppler.dll.a

b)Then in  Settings-Compiler-Search directories-Linker
I set the path to:
C:\Users\Chris\Documents\Poppler\build\poppler-0.22.2_Build\

c)Then I set up the linking for my project:
Project-Build Options-Linker settings
and set the path to
C:\Users\Chris\Documents\Poppler\build\poppler-0.22.2_Build\libpoppler.dll.a

d)And finally:
Project-Build Options-Search directories-Linker
and add the path:
C:\Users\Chris\Documents\Poppler\build\poppler-0.22.2_Build\

4) I have now written the following code in my main.cpp just to see if
everything works:

1 : #include iostream
2 : #include
C:\Users\Chris\Documents\Poppler\build\poppler-0.22.2\cpp\poppler-global.h
3 : #include
C:\Users\Chris\Documents\Poppler\build\poppler-0.22.2\cpp\poppler-document.h
4 :
5 : using namespace std;
6 :
7 : int main()
8 : {
9 :
10:
11:   const string dir =
C:\\Users\\Chris\\Documents\\WorkForDad\\2013\\Pdf Automation\\Anotation
Extraction\\Remuneration Report.pdf;
12:
13:poppler::document *doc = poppler::document::load_from_file(dir);
14:
15:return 0;
16: }

However, I get the following error in myBuild messages when I build the
code:


C:\Users\Chris\Documents\WorkForDad\2013\Pdf
Automation\Test\Clean\main.cpp||In function 'int main()':|
C:\Users\Chris\Documents\WorkForDad\2013\Pdf

||=== Build finished: 1 errors, 1 warnings (0 minutes, 1 seconds) ===|

And in the Build log I get the following:

So as you can see, the problem would seem to be a linking error of some
sort due to the
