[SOLVED]Integrating Poppler in QT4

[dreamerindia]

Dear All,

I'm trying to integrate the pdf viewer in my Qt application.I found poppler is widely used pdf library and tried to build the example program((http://doc.qt.digia.com/qq/qq27-poppler.zip)) from "http://doc.qt.digia.com/qq/qq27-poppler.html".But its showing the build error.
@g++ -o pdfviewer documentwidget.o main.o window.o moc_documentwidget.o moc_window.o moc_poppler-optcontent.o -L/usr/lib -L/usr/lib -lpoppler-qt4 -lQtGui -lQtCore -lpthread
/usr/bin/ld: cannot find -lpoppler-qt4
collect2: ld returned 1 exit status@
I installed the poppler as mentioned in "http://www.linuxfromscratch.org/blfs/view/svn/general/poppler.html"

Can anybody help me in this issue?

Hi,

Are you sure your poppler library is called poppler-qt4 (as in libpoppler-qt4.so) ?

If you are using a distribution: what is it and did you try to install the dev package for poppler using the distribution package manager ?

[dreamerindia]

Hi,Thanks.

I have the following files
@/usr/lib/libpoppler-qt4.so.3
/usr/lib/libpoppler-qt4.so.3.2.0@

I installed(./confure && make && make install) poppler-0.22.3 which i got from http://poppler.freedesktop.org/

"dev package for poppler using the distribution package manager "- No i not did this
what is it and how to do that?

[SGaist]

Short version: you are missing a symbolic link call libpoppler-qt4.so.

@ln -s /usr/lib/libpoppler-qt4.so.3 /usr/lib/libpoppler-qt4.so@

As for the package stuff: are you using a linux distribution ?

[dreamerindia]

hi,

Thank you. your right i'm missing symbolic link.

after

@ ln -s /usr/lib/libpoppler-qt4.so.3 /usr/lib/libpoppler-qt4.so @

it works fine.

thank you very much.

Hi,
It is working fine in x86 compiler.
But how to get the libpoppler-qt4.so for ARM compiler.
or How to cross compile poppler for ARM.

Configuring with "./configure --host=arm-linux-gcc" will work right?

[dreamerindia]

Hi,

I am trying to configure with cross compile with no success

i used

@./configure --host=/usr/local/DigiEL-5.6/x-tools/arm-cortex_a8-linux-gnueabi/bin/arm-linux-g++ --prefix=/usr/local/DigiEL-5.6/x-tools/arm-cortex_a8-linux-gnueabi/arm-cortex_a8-linux-gnueabi/sys-root/usr/lib/ @

its generating the

libpoppler.so,libpoppler-cpp.so 's but not the libpoppler-qt4.so or its derivatives.

[SGaist]

Did you cross-compile or already have all dependencies for poppler ? If you don't have Qt for ARM, it won't build it

[dreamerindia]

yea i'm using the QT for ARM integrated in Eclipse C++ IDE.when i compile it with arm-linux-gcc its not creating the libpoppler-qt4.so or its derivatives but creates the libpoppler-cpp.so in ARM compile.

[dreamerindia]

I tried with libraries from
@https://launchpad.net/~ubuntu-security/+archive/ppa/+build/4407291@
But its showing undefined references....
@./lib/libpoppler-qt4.so: undefined reference to PDFDoc::isLinearized()' ./lib/libpoppler-qt4.so: undefined reference to FormWidgetText::noSpellCheck() const'

Are you sure that the build system finds your arm Qt ?

If you download pre-built package, you also have to download their dependencies

[dreamerindia]

can you pls tell me where i can find the source package for arm linux(armel).i tried different sources compilation.

[dreamerindia]

yea i installed binaries for arm and its dependencies.finally its throwing only one error..

@
/lib/libpoppler.so: undefined reference to `__longjmp_chk@GLIBC_2.11'
@

[SGaist]

It means a package has been linked to a pretty old version of glibc. Are you sure you downloaded the latest version of the armel libraries ?

[dreamerindia]

which one is older version libpoppler.so? or libpoppler-qt4?

[SGaist]

They should be same since they are built at the same time

[dreamerindia]

hi one library need libssl.s0.1.0.0 and another needs libssl.s0.1.0.1
how to deal with this. if i create soft link for one of it another is not working.pls help

[SGaist]

Seems there's something wrong in your dependencies. Check that you download all packages from the same distribution

[dreamerindia]

Actually i downloaded dependencies www.openmamba.org
how to ensure it as from same distribution?

[SGaist]

Don't know this one, generally if I need to download precompiled package I go for the debian armel architecture.
