Hi Jan,

could you provide some more info of what you are trying to do and when this error happens? Please also provide your exact Linux distribution version.

Best,

Ubuntu Studio 23.04 (KDE)

Just try to build my project I can run in CLion and QtCreator without problems.

It happens in linking stage:

[build] /usr/bin/ld: /home/czarek/Felgo/Felgo/gcc_64/lib/libFelgo.a(unzip.o): undefined reference to symbol ‘inflateEnd’
[build] /usr/bin/ld: /lib/x86_64-linux-gnu/libz.so.1: error adding symbols: DSO missing from command line
[build] clang: error: linker command failed with exit code 1 (use -v to see invocation)
[build] ninja: build stopped: subcommand failed.

And funny – I have not direct reference to libz library

target_link_libraries(${PROJECT_NAME} PRIVATE
Felgo
Qt6::Charts
Qt6::Svg
Qt6::WebView
crypto
ssl
)

Hi Jan,

2 things to try:

First make sure that the basic build dependencies are installed: https://felgo.com/doc/felgo-installation/#install-felgo-on-debian-ubuntu-derivatives

If that is the case and it still does not work, please try to add

target_link_libraries(appMyProjectName -lz)

with your own project name to your CMakeLists.txt of your project.

Best,
Alex
