LIBS+= behaviour on Windows

[Benne Gesserit]

This must be a very newbie question ,but I m both confused and frustrated ,I have looked around for a while (escuse me if somewhere else there is a right answer forr my question) and didnt find an explanation .
It s simple : I want to add more library paths and more libraries to my makefile .What should I put after LIBS+= ? Well ,that sounds I little bit stupid . I mean : http://doc.trolltech.com/4.4/qmake-variable-reference.html#libs
should I add full paths to libraries ? If I do that ,the makefile generated looks like this : (just the interesting part)


-L"i:\Qt\4.4.0\lib" -lmingw32 -lqtmaind I:\MinGW\lib\libaclui.a -lQt3Supportd4 -lQtGuid4 -lQtCored4

If I do LIBS+= -L" I:\MinGW\lib\" (just to add a path) :


-L"i:\Qt\4.4.0\lib" -lmingw32 -lqtmaind -LI:\MinGW\lib -lQt3Supportd4 -lQtGuid4 -lQtCored4

Is that correct? Shouldnt it add " at the begin and end of the path? Can the path have spaces?This way it seems to work ,but it s not the way the documentation says it should be ,is it?
Ok ,lets sum up : I someone can tell mee the syntax of LIBS+= in .pro on windows I would really ,really apreciate it.

Thanks in advance.

Where does it say so?


You can use the Unix -l (library) and -L (library path) flags and qmake will do the correct thing with these libraries on Windows (namely this means passing the full path of the library to the linker).

Ok ,maybe I misunderstood the documentation .
But ,then ,is it fine if in the makefile qmake puts -Lpath instead of -L"path" ? And can the path have spaces? Probably I will be testing that tomorrow ,but just to make it clear and in case anyone finds the same doubts .

[Benne Gesserit]

Ok ,I think I got my answers .I have just been working with libpaths with spaces and I think the conclusion is : when you want to add a libpath with a space ,you ve got to do it like : -L "path" .
Note the space between the 'L' and the first " .Otherwise ,I think qmake will have problems with the " (placing them somewhere else or just erasing them) or with the spaces in the path .
Hope this helps someone else and saves some time .Maybe I am the only fool who has to spend some time wondering how to do such a thing .

"-Lpath with spaces" (with -L inside the quotes) would have also worked, I think.

[Benne Gesserit]

Yes ,you are right .At least it seems to work .But....I dont like it .It s confusing ,you always see -L"path" ,then you see "-Lpath"....seems to be a mistake .Anyway ,it s good to know it can be used that way,
Thank you very much.

No, "-Lpath" is correct because quotes surround the whole argument and that's the meaning of quotes - to build a parameter containing spaces you surround it with quotes, not that you surround spaces with quotes or surround parts of the argument containing spaces with quotes.
