How to compile using Ubuntu 18 repo libraries only

[ocgltd]

I have installed Qt Creator on Ubuntu 18, and compiled my app against Qt 5.9.8 which I installed with Qt Creator.

I copied my executable to another Ubuntu 18 box, and added the Qt5* libraries from the default repo. And I confirmed the libraries are version 5.9.8

However, when I run my program I get error:

relocation error: ./myapp: symbol _ZdlPvm version Qt_5 not defined in file libQt5Core.so.5 with link time reference

From what I read online there is some kind of mismatch in the libraries. So, I built another Ubuntu 18 VM where I would like to recompile my app. This time I won't install Qt Creator, I just want to add the Qt5 libraries from the "Default" repo. But I can't figure out what to add.

Which Ubuntu libraries/tools do I need to install to compile my app?

build-essential and qtbase5-dev should get you started.

Hi,

Which modules are you using ?

You can start with qtbase5-dev and add all the modules you use with corresponding packages.

According to ldd my app needs:

       linux-vdso.so.1 (0x00007ffd3fbf7000)
       libQt5Network.so.5 => /opt/Qt/5.9.9/gcc_64/lib/libQt5Network.so.5 (0x00007fed62674000)
       libQt5Sql.so.5 => /opt/Qt/5.9.9/gcc_64/lib/libQt5Sql.so.5 (0x00007fed6242d000)
       libQt5Core.so.5 => /opt/Qt/5.9.9/gcc_64/lib/libQt5Core.so.5 (0x00007fed61ce6000)
       libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fed61ac7000)
       libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007fed6173e000)
       libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007fed61526000)
       libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fed61135000)
       libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fed60f18000)
       libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fed60b7a000)
       libicui18n.so.56 => /opt/Qt/5.9.9/gcc_64/lib/libicui18n.so.56 (0x00007fed606e1000)
       libicuuc.so.56 => /opt/Qt/5.9.9/gcc_64/lib/libicuuc.so.56 (0x00007fed60329000)
       libicudata.so.56 => /opt/Qt/5.9.9/gcc_64/lib/libicudata.so.56 (0x00007fed5e946000)
       libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fed5e742000)
       libgthread-2.0.so.0 => /usr/lib/x86_64-linux-gnu/libgthread-2.0.so.0 (0x00007fed5e540000)
       libglib-2.0.so.0 => /usr/lib/x86_64-linux-gnu/libglib-2.0.so.0 (0x00007fed5e229000)
       /lib64/ld-linux-x86-64.so.2 (0x00007fed62a06000)
       libpcre.so.3 => /lib/x86_64-linux-gnu/libpcre.so.3 (0x00007fed5dfb7000)

I grabbed the above from a different system, but hopefully that answers question. Under centOS I found instructions for adding all compiler tools in one step, and Qt packages. But can't find anything similar for Ubuntu

@SGaist said in How to compile using Ubuntu 18 repo libraries only:
I added the above packages plus qt5-default and I was able to compile. I also moved my old Qt (installed from Qt Creator) from /opt/Qt to /tmp/Qt so there would be no conflict.
