Install Qt3 from source on Ubuntu 12.10



  • Hi there,

    I am running some software that needs Qt3 to run so I am attempting to install it from source. I downloaded the following source file from the Qt website qt-x11-free-3.3.8.tar.gz. I unpacked it, copied everything into a new directory call qt and did ./configure. That all went fine as far as I could tell. I run into trouble when I run make though. I will copy and paste the output here but its a lot. Any help/advice is appreciated.

    make output:
    mcbridej@schlock:~/qt$ make

    Hi and welcome to devnet,

    What about using qt3-dev-tools from ubuntu ?

    You should also consider porting that software to Qt5/4



  • They are apparently not available in 12.10 and I don't have su access. I did not develop this software so it has to be run using qt3.


  • Lifetime Qt Champion

    Since you have the code, you can port it (and you really should).

    Or just use a virtual machine containing an older version of Ubuntu still providing Qt 3. At least 12.04 still does.



  • The system admin for our computers will only run a Virtual Machine for a limited time on that computer. Also the program runs out of memory and harddrive space really quickly because of this program.

    I can try porting. Again its not my software, and on their website they say to use Qt3 http://www.astro.uni-bonn.de/theli/gui/installation.html

    And the port is not trivial…

    In that case, just add

    @#include <stddef.h>@

    In the files where there's a complaint about ptrdiff_t
