    Hello. I am trying to build Qt-5.12.9 from source on Nvidia Jetson Nano, ubuntu 18.04.5 LTS (GNU/Linux 4.9.140-tegra aarch64). I would like to use sytem libjpeg. At the configuration time I specify -system-libjpeg with -v. After the configuration is done I get this:

    JPEG ................................. yes
      Using system libjpeg ............... yes
    PNG .................................. yes
      Using system libpng ................ yes

    And

    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

    If I continue with the configuration and build. when I run my app I receive this:

    JPEG prarameter struct mismatch: library thinks size is 584, caller expects

    In my app:

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

    In my system:

    ldconfig -p | grep libjpeg
	libjpeg.so.8 (libc6,AArch64) => /usr/lib/aarch64-linux-gnu/libjpeg.so.8
	libjpeg.so (libc6,AArch64) => /usr/lib/aarch64-linux-gnu/libjpeg.so
dpkg -l

    How do I link only with libjpeg8 so -system-libjpeg will find only this? Thank you

    Hi,

    I think the easiest would be to remove the development package of the version you do not want to use. It will avoid its detection.

    @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

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

    So everything looks correct...

    How are you loading your image in your application ?
