[Solved] I cant use "auto" keyword in Qt 5.1.2 into Ubuntu

Charlie_Hdz

Hi.

Im trying to develope in Qt (IDE and GUI) but all the time im found problems and now the actual problems is the type "Auto" defined in C++ 11.

Now, i have typing the keyword auto for declare a iterator and in the time of debug the solution, Qt set me a problem:

"auto" changes the meaning in C++ 11; please dont use it.

Somebody can help me?

Hi Charlie_Hdz,

Did you add -std=c++11 or -std=gnu++11 in Qt Creator project settings?

C++11 is not activated by default in Qt Creator.

Hi Eddy.

I did it and works

I add in .pro of the project CONFIG += c++11 and works.

Thanks you :)

Eddy

Great

Could you mark the thread as [Solved] please?

Hi,

Just a little trick, when writing a post with pro file content also use the coding tags e.g.

@CONFIG += c++11@

Otherwise it's likely to get misinterpreted by the current text engine used. Your's look like CONFIG = c+11 even if it's written correctly.

Thank you very much SGaist and Eddy i solved the problem; now if dont is to much trouble for you all, you can help me in the next link:

I have Qt to Linux and Windows and the both case i have too much troubles about complier and debugger.

The next problem is about the watch of local variables in debug mode.

The debugger only show me a changed value, for example:

i declare a unsigned long long and i expect a value in the watch such:

00000001-00000002

but the debugger only show :

2
