Mai65 commented 5 months ago

Hi, I am currently trying to compile the project by using the following commands: 

cmake -DCMAKE_BUILD_TYPE=Release \
          -DCMAKE_INSTALL_PREFIX=/usr \
          -DKDDockWidgets_FRONTENDS='qtwidgets;qtquick' \
          -DKDDockWidgets_QT6=true \
          .
    cmake --build .

which results in the following error: 

[ 58%] Automatic RCC for ../../dockwidgets/resources_example.qrc

I checked if curl is installed: it is. This is the output of ls /usr/lib | grep curl: 

libcurl-gnutls.so

Hope someone can help me.

Hi,

Can you clone: https://github.com/iamsergio/test-minimal-qtquick.git

and see if it gives the same linker error ?

Mai65 commented 5 months ago

Hi thanks for providing the minimal example. I took the following steps: 

git clone https://github.com/iamsergio/test-minimal-qtquick.git
cd test-minimal-qtquick/
cmake .

this resulted in the following output of cmake:

This looks like a successful build to me. However, if you have a different opinion, please let me know.

Thanks for your help so far.

And cmake --build . worked as well ?

Sorry forgot to add that...

Looks fine for me as well.

Paste a verbose build of kddw, something like: VERBOSE=1 cmake --build

Sorry, I meant in KDDockWidgets

Mai65 commented 5 months ago

Oh sorry. Here it is: output.log

iamsergio commented 5 months ago

there's no error in that output, seems truncated ?

Mai65 commented 5 months ago

My fault... forgot to redirect the error stream...

output.log

iamsergio commented 5 months ago

ok good. Can you now go back to the mini-qtquick example, do a git pull and see if that one still builds ?

Mai65 commented 5 months ago

There is no new commit in https://github.com/iamsergio/test-minimal-qtquick.git

iamsergio commented 5 months ago

oops, forgot to push, try now :)

Mai65 commented 5 months ago

Seems like there is no problem. Here is the verbose log output.log

iamsergio commented 5 months ago

ok, just one more. Pull again from test-minimal

Mai65 commented 5 months ago

Still seems fine output.log

iamsergio commented 5 months ago

No idea then, that output looks OK. I still doubt it's a KDDW bug though, as we don't use libpxbackend or curl or libproxy
