Deploying Qt Application under Linux

[addu]

Hi

i referred the ldd and ld.so commands

In Qt unstalled systems i ran the following command.

ldd ./my application

it gave me

libQtCore.so.4 not fond
libQtGui.so.4 not found

But i have plaed both libs in my application folder.

Now i ran ./configure -static -prefix /qt instaliton path

then i have used make command

Then i went ot lib of Qt .. there i have the command make install..

still i didn't replace old libs , once i replaced and update here


Thanks

As stated above, unless the application directory is contained in LD_LIBRARY_PATH, then its not going to find the libraries in the application dir. You shouldn't be messing with LD_LIBRARY_PATH either, but instead package your application so the installer will automatically install Qt if its not there already. Why include 10MB of libraries if you don't have to?

Thanks for your reply

I used libs path in my application. I got solved issues regarding qt libs

Now new issues has been raised

It is showing Glibc _2.4 not found


Then i installed glibc_2.7 ,but i am getting same error.. is i have
install same version ?

Thanks

Same erro here.

I'm using Kubuntu 10.04 to develop and a fresh install of Kubuntu 8.04 to execute but it falls.

if I use Qt static libraries:

./bcFinal
./bcFinal: /lib/tls/i686/cmov/libc.so.6: version `GLIBC_2.9' not found (required by ./bcFinal)
./bcFinal: /lib/tls/i686/cmov/libc.so.6: version `GLIBC_2.11' not found (required by ./bcFinal)

if I use Qt shared libraries:

Segmentation fault.

What I can do to solve this ?

Linux, like all operating systems, does NOT guarantee backward compatibility. If you developed under Kubuntu 10.04, your app is NOT going to run under Kubuntu 8.04 or any other version earlier than 10.04. Your application fails because the C runtime version it was built against doesn't exist on your test machine.

Thanks for the answer.

What Qt in static mode can I install in kubuntu 8.04 to compile and excute my app ? Qt 3 or Qt 4 ? Where can I download ?

[Thà nh Viên Mới]

which libs gcc download ?, can you help me
