Eclipse question

[MarkoSan]

Good morning, sehr geheerte Damen und Herren!

What does it mean Eclipse warning:

No line 0 in file "CFlagButton.cpp".

No line 0 in file "CFlagButton.cpp".

To copy to clipboard, switch view to plain text mode 

Can someone answers this?

How do you get this warning? I'm mean, what did you do? Did you just write the code and try to run/compile/debug it?

[MarkoSan]

Yep, I just wrote the code and try to debug it. And this warning is not shown every time, it seems to me it is shown randomly ....

[Keith Ross]

I have the same issue. "No line 0 in file ..." prints when using mingw-6.8 gdb with eclipse 3.4.1 (Mylyn), Qt integration 1.4.3 installed. Using gdb from a dos prompt works fine. I have sent up my gdb as in the attched pic. I have also added the text for a gdb session. A segment of this text is below. The issue seems to have no effect other than making debuging slow because of all the "No line 0..." lines being printed continuely.

I don;t know if this issue is Eclipse, or the Qt integration. I have try different eclipse versions, different code, and different mingw gdb versions. All the same.

Any suggestions?

I can comfirm that Qt integration had no affect as "No line 0 in file ..." appears with just gdb and eclipse.

[Keith Ross]

I have found a setup that works with the same code, eclipse. The gdb text is attached so you can compare with the last one. The main difference is that the Qt integration plugin has added alot of extra stuff when it created a project.
