ERROR: ldd outputLine: "libicui18n.so.56 => not found"

Question

I want to use linuxdeployqt tool, but this command: ./linuxdeployqt-continuous-x86_64.AppImage /home/user/QtProjects/build-VPSTest-Desktop_Qt_5_6_0_GCC_64bit-Release/VPSTest

Outputs this:

Not using FHS-like mode
app-binary: "/home/user/QtProjects/build-VPSTest-Desktop_Qt_5_6_0_GCC_64bit-Release/VPSTest"
appDirPath: "/home/user/QtProjects/build-VPSTest-Desktop_Qt_5_6_0_GCC_64bit-Release"
relativeBinPath: "VPSTest"
ERROR: ldd outputLine: "libicui18n.so.56 => not found"
ERROR: for binary: "/home/user/QtProjects/build-VPSTest-Desktop_Qt_5_6_0_GCC_64bit-Release/lib//libQt5Core.so.5"
ERROR: Please ensure that all libraries can be found by ldd. Aborting.

Next I did this: ldd libQt5Core.so.5

This command outputs:

libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007ff552c43000)

libpcre.so.3 => /lib/x86_64-linux-gnu/libpcre.so.3 (0x00007ff55122f000)

Next I opened /home/user/Qt/5.6/gcc_64/lib/, this is location of the libQt5Core.so.5, and of course I found libicui18n.so.56, libicuuc.so.56 and libicudata.so.56.

So, how can I fix this issue and create deployment bundle using linuxdeployqt tool?

Maybe adding /home/user/Qt/5.6/gcc_64/lib/ to the LD_LIBRARY_PATH will help? – Rhombohedron

You can usually have multiple versions of libicu : Install "libicu56" . But you will of course have to edit your question to include OS name, version, arch ... if you want a link to libicu56. – Stuffy

I used this solution:

PATH=/home/user/Qt/5.6/gcc_64/bin:$PATH
export PATH
