      @SGaist Thanks for replying. Actually I tried to remove, however it seems that libjpeg-turbo8-dev install the rest as dependencies. So when removing it warns about the depencencies and if I remove then install again it will install all.

        Something is not clear what exactly depends on libjpeg-turbo-dev ?

            Sorry, it just realized I misread your issue.

            You built Qt successfully but have a problem with your application.

            Are you loading a specific file that triggers this error or does it happen for all jpeg files ?

              @SGaist Just camera and opencv however the same code runs well without problems on a Raspberry Pi with Qt 5.11.3

                @SGaist I believe this libjpeg mismatch:

                ldd myapp
                .....
                libjpeg.so.8 => /usr/lib/aarch64-linux-gnu/libjpeg.so.8 (0x0000007fa6283000)
                .....
                

                and qt configure with -system-libjpeg

                Checking for libjpeg... 
                Trying source 0 (type inline) of library libjpeg ...
                  => source failed condition 'config.msvc'.
                Trying source 1 (type inline) of library libjpeg ...
                + cd /home/ath/Documents/SourceCode/qtBuild/config.tests/libjpeg && /home/ath/Documents/SourceCode/qtBuild/qtbase/bin/qmake "CONFIG -= qt debug_and_release app_bundle lib_bundle" "CONFIG += shared use_gold_linker warn_off console single_arch" 'QMAKE_USE += libjpeg' 'QMAKE_LIBS_LIBJPEG = /usr/lib/aarch64-linux-gnu/libjpeg.so' /home/ath/Documents/SourceCode/qtBuild/config.tests/libjpeg
                + cd /home/ath/Documents/SourceCode/qtBuild/config.tests/libjpeg && MAKEFLAGS= /usr/bin/make
                > g++ -c -pipe -O2 -w -fPIC  -I. -I/home/ath/Documents/SourceCode/qt12Source/qtbase/mkspecs/linux-g++ -o main.o main.cpp
                > g++ -Wl,-O1 -fuse-ld=gold -o libjpeg main.o   /usr/lib/aarch64-linux-gnu/libjpeg.so   
                 => source accepted.
                test config.qtbase_gui.libraries.libjpeg succeeded

                  libjpeg.so is likely a symbolic link to libjpeg.so.8

                        So everything looks correct...

                        How are you loading your image in your application ?
