Problem with compilation

[klukaspl]

Hi,

when compiling I reached the following issue:

Message.cpp: In member function ‘void sdbus::Message::seal()’:
Message.cpp:553:83: error: ‘sd_bus_message_seal’ was not declared in this scope
auto r = sd_bus_message_seal((sd_bus_message*)msg_, messageCookie, sealTimeout);
^
Message.cpp: In function ‘sdbus::Message sdbus::createPlainMessage()’:
Message.cpp:669:72: error: ‘sd_bus_message_new’ was not declared in this scope
r = sd_bus_message_new(bus, &sdbusMsg, _SD_BUS_MESSAGE_TYPE_INVALID);

Could you please give me a hint how to avoid those errors?

BR,

Krzysztof

Hi Krzysztof,

your systemd library is older than is needed.
You need to have at least v236: https://github.com/systemd/systemd/blob/v236/src/systemd/sd-bus.h#L232

BR,

Hi Lukas,

Thanks a lot! Indeed I am using Kubuntu 16.04 with libsystemd-dev v229, and there is no newer for it from official packages. I am a bit afraid to upgrade manually to not break something in my OS.

Thanks
Krzysztof

You are welcome. 18.04 LTS will be published very soon and it will have the version you need.
