Hi,

Where did you the QtWebKit sources from ?

Hi,
I did a git clone from

[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = https://github.com/qt/qtwebkit.git
fetch = +refs/heads/:refs/remotes/origin/
[branch "5.212"]
remote = origin
merge = refs/heads/5.212

Your issue is caused by mismatch between ICU headers and libraries. How do you build QtWebKit?

msauer75

Hi,
I downloaded the sources with git and create a build directory. Inside the build dir I called

ccmake -DCMAKE_PREFIX_PATH=/opt/Qt/5.12.0/gcc_64 ../.

I want upload the cmakecache.txt file, but I can't

Please use -DQt5_DIR instead of -DCMAKE_PREFIX_PATH to specify Qt path, as described in wiki. Use fresh build

Hi,
thank you for your help. This works.
I'm newbie to compiling this one, so what is the different between the two invocations?

CMAKE_PREFIX_PATH causes cmake to pick ICU libraries from Qt SDK while using system ICU headers (which have different version)

Hi,

from git I get the version 5.212.0. After the compilation I will get a incorrect version error from cmake in digikam. I should use the exact version 5.12.x.
Is ther an error in the git sources or did I a mistake?

@msauer75 You have to rebuild digikam with new Qt and QtWebKit libs that you are using
