Display PDF file in Qt app

Massi

Dear Qt forum,

Is it possible to display pdf file within my Qt GUI? I have tried with poppler according to link text but I never succeed to build it. I got many errors like: LNK1104: cannot open file ‘..\Debug\poppler.lib’

I would appreciate your help!

Cheers,

Massi

Hi,

Where's you poppler lib located ?

Hi Massi

wihtout poppler lib you can´t link to poppler. On windows it´s an exhausting task to get all dependencies to compile poppler. I have a set of working release and debug builds for poppler-qt5 created with msvc2013. You can get them if this setup suits you.

@SGaist Thank you for your reply! I started by building poppler link text using CMake with vs2008 + Qt4 under win7 64x with linking all the dependencies (freetype, zlib, openjpeg, cairo). After building the solution in vs2008, I got the following errors (There is no poppler-qt4.lib at all in my folders):

@sneubert First I really appreciate your help!! Actually I'm using vs2008 + Qt4 under win7 x64. I really don't know how to get the poppler lib. It seems more difficult to build than using it!!

The first error explains the problem. You are doing a 32bit build but you have a 64bit Qt version. You need to build poppler with a 64bit compiler or get a 32bit Qt install. I don't think VS2008 will do 64 bit.
