[Moved] Define a macro on Qt for Embedded Linux
-
I try to define a macro for Embedded Linux project. this is what i write:
@
#ifdef Q_WS_WIN // Windows
const QString BASE_DIRECTORY = "C:/path/on/windows";
#elif defined(Q_WS_QWS) || defined(Q_WS_QPA) // Embedded linux
const QString BASE_DIRECTORY = "/path/on/board";
#else // Linux
const QString BASE_DIRECTORY = "/home/path/on/linux-ubuntu";
#endif // OS type
@on the board that is Embedded Linux *lighthouse * version the BASE_DIRECTORY is equal to
"/home/path/on/linux-ubuntu" .how can i figure out the OS version, and fix it?
tnx

[quote author="Anticross" date="1325160416"]I think this not right branch of forum to ask such questions. Post in Mobile and Embedded.[/quote]
This might not be the best place to post for everything, but reposting the same thing in different forums is not a good solution either. Someone of the moderators will eventually move the topic.

What do you mean with figuring out the OS?
Typically the information you are using in your example would be part of some defines you are using. -
i need to define a path that will be avalible only on the embedded system and i can't find the right define to achieve that.
In the example you can see that I try
@#elif defined(Q_WS_QWS) || defined(Q_WS_QPA) // Embedded linux
@
but it does not work and i entered into the default:
@#else // Linux
const QString BASE_DIRECTORY = "/home/path/on/linux-ubuntu";
#endif // OS type

I guess you have compiled Qt for cross-compilation to use with your embedded platform.
Duirng configuration there is typically a sequence like "-xplatform qws/linux-arm-g++" for example. All default macro definitions can be found in "mkspecs/qws/linux-arm-g++" in your cross compiled installation (respective any compilation). Probably you have to follow different include files until you find the master. However, there you find all definitions for compilation.
