How to solve Error 1: collect2: ld returned 1 exit status

[Qtime]

Hi,

I just downloaded QT.2009.03 for windows and tried to make a gui application.
It gives :-1: error: collect2: ld returned 1 exit status when building the program.

can somebody suggest me the solution.

ld didn't find libraries needed for your application. The possible reasons:
bug in the application code or you didn't install (improperly installed) some libraries.

Another reason might be that your source is incomplete and calls method DECLARATIONS that get called but the method IMPLEMENTATIONS are missing.

Declaration is the stuff that you usually put in a header file (method signature without body)
Implementation is the signature with body.

Usually if you look in the linker output, you can find which implementation the linker is missing.

Qtime, click the "Compile Output" view (Alt+4) to see more detailed info.

From there you should be able to determine the error yourself.

Or you can paste the complete output here in the forum as it'll be more helpful than the concise error message you provided.

I often get this error, then i forget to close my previous builded application and after small changes i try to build it again sometimes old instance of program runs in background so you can't see it, then you might need to close it by using windows task manager or in Linux kill command.
