Please, when you have compilation or execution errors, recompile each component without using an AUR helper before reporting an issue.

@FineWolf is right, thanks! yay -S seafile --rebuild solves the issue for me, too.

@FineWolf thanks, rebuilding the seafile package (not seafile-client) works for me.

@meromorphic Better yet, simply do a new clean build of the seafile package manually or using your favorite AUR helper.

It will compile against the new version of libwebsockets.

Just a heads-up: after yesterday's (August 15, 2025) update of libwebsockets (https://archlinux.org/packages/extra/x86_64/libwebsockets/), the seaf-applet and daemon do not start. "seaf-cli start" fails with "error while loading shared libraries: libwebsockets.so.19: cannot open shared object file: No such file or directory." Which is perfectly correct, libwebsockets.so.19 is replaced with libwebsockets.so.20. For the moment, "sudo ln -s /usr/lib/libwebsockets.so.20 /usr/lib/libwebsockets.so.19" seems to make the client function again.

@trap000d ,works now ,thank you

Thanks @trap000d for the patch.

@xhikari, Looks like changes in Qt6.9. After adding a couple of #include package seems builds OK.

See patch here:

Getting the error below during make, anyone else getting this?

When I build the client and it hits 100%, I get the following error:

I tried to build it via pamac, the software tab and building it myself and it always ends with the same error. Does anyone know how to solve this?

For quite some time I get an error when building the package. So far, I have tried to install it from the Software Tab on Manjaro, via yay, via pamac and I tried building it myself. All attempts have failed with the same error.
