Integrate custom lib

Sikarjan

Hi,

I am working on an app for Sailfish OS. I need to prevent the system from going into sleep. Otherwise my timer will not work properly and with it my app.

Unfortunately I am not allowed to use the build in libkeepalive library. I need to "build in" this library in my app but I have no idea on how to do that. Currently I am in desperate need of these things:

Which files should I get from this repository?
Where should I put the files in my project (need I to compile something first or can I use them directly)?
How do I make the component KeepAlive available in my app?

my current source code can be found on github, in case that helps to answer my questions.

I would be grateful for any hints in the right direction!

Hi,

Out of curiosity, why can't you use that library ?

Why not build that library yourself and then link to it in your project ?

Hi,

the harbour rules only allow a couple of libs, the others are not "stable" enough, yet and libkeepalive is not on their list. So my app got turned down by QA.

I have not build the library my self because I have not done such a thing before. I have been trying to read up on it but the examples I read were not for Sailfish OS.
To build it my self I only need to open the .pro file from the lib folder and run build? On the machine I tried it on that failed because libiphb development package not found but I do not have the Sailfish SDK installed on this one.
I guess I need to configure the project for arm. Anything else I need to keep in mind?

Hi again

So I compiled the pro file from the plugin folder against arm7 and got an libkeepaliveplugin.so file. That is the one I need, right?
I copied the file in my project under plugins/. To include it I added these lines to my pro file

INCLUDEPATH += plugins/
LIBS += -L plugins/ -lkeepaliveplugin

and in my QML file I tried

#import Nemo.KeepAlive 1.1

but the IDE tells me that it could not find that and when I try to compile I get the error:

/opt/cross/bin/armv7hl-meego-linux-gnueabi-ld: cannot find -lkeepaliveplugin

What am I doing wrong here?

You usually don't link against a plugin, you use it at run time.

In any case, you should contact the SailfishOS folks about that matter.
