-
No .I dont think this..I have build succefully and run ..but some function not work because some api are obsolete..But i couldnt find obsolete api..because i have not find error of obsolete api..I cant explain exact where problm is generated
-
Hi
ok. it will most likely result in the same error as it seems to be something with /usr/include
What we are trying to tell you is that 4.8.7 IS very close to 4.8.1 so
the application should work and we are not sure what API should be obsolete as
it should not be the case. -

It's not a problem of the tar ball. Qt 4.8.7 was released almost 8 years ago so 4.8.1 is even older. Compilers have changed in between.
Hence our recommendation from the start: use the version provided by your distribution. It has been compiled with the compiler you are currently using.
If the application uses API that have been obsoleted, then these are likely API that shouldn't have been used from the start. Qt uses deprecation to warn people about APIs that should not be used anymore and usually obsoletes them in major release change so an obsolete API should not be taken lightly.

Thank you all of you for your great response..
@mrjj I have compile and run code using qt 4.8.7 .its build without single error and run also..but after run application not show name of any widget.@vaibs
Hi
Ok, that is pretty strange.
i assume normally around the green area, there would be
some buttons or similar.
I have this strange feeling it might be related to unity.
Would it be possible to try to run the exe on other linux ? -
@mrjj Thank you .. Yes I have try..but i dont get any solution for this.. any another solution for display widget on gui after run?.I cant understand why this issue is generated..

Hello,
AS I read you want to install qt 4.8.1 First you have to download qt4.8.1 and place it on desktop.
Then you have to open the terminal in your Ubuntu and enter your path of the desktop.
Then you have to install some required dependencies
sudo apt-get install build-essential check install
After that, You have to extract that qt4.8.1 file using commands
ar -xvzf qt-everywhere-opensource-src-4.8.1.tar.gz
Then go to the extracted folder using
cd qt-everywhere-opensource-src-4.8.1
And then run Via follow these- ./configure
make
sudo check install
Then you can install it via apt
sudo dpkg -i path/to/output.deb
Change path/to/output.deb to the path of the created .deb file.
Hope this will help you.
Thanks - ./configure
