[SOLVED]Integrating Poppler in QT4

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.

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.

dreamerindia

now trying to solve this error.

dreamerindia

finally managed to compile successfully.

but its showing error in runtime as

@

/home/pdf_viewer # ./pdfviewer -qws
./pdfviewer: error while loading shared libraries: libpoppler-qt4.so.4: cannot open shared object file: No such file or directory

@

what is the problem ? :-)

dreamerindia

Yea finally it came. copied .so files to target lib folder.SUCCESS!!!!

Thank you very much for your suggestions :-)

Dear SGaist..... why its slow when loading files greater than 1 MB....
