174 errors on "make" (Linux Jamulus client 3.4.4)

[Gronaz]

Please what can trigger these ?
Even the binary is built and seems to work, is it a serious problem?
Thanks

[Volker Fischer]

These should be warnings. They should be gone in Jamulus version 3.4.5.

[Gronaz]

No problem? Can I run as is?

[Volker Fischer]

Yes, you can. I also got these warnings.

[Gronaz]

Thank you Volker
So it is the same for errors on building server I guess (qmake "CONFIG+=nosound" "CONFIG+=noupcasename" Jamulus.pro) ? There are more (about twice) but it builds and runs.
