Problem compiling c++ win7 MinGW "_unwind_resume"

[rolfarj]

Hi. I just reinstalled codeblocks because of some problems. Now, i cant compile my C++ projects (have not tried any other languages).

The message i get is "undefined reference to '_unwind_resume' ".

-I am running windows 7
-I downloaded the latest codeblocks with mingw included.
-I have included C:\Program Files\CodeBlocks\MinGW\bin to the system path
-I tried installing codeblocks withoud mingw and downloading mingw seperately. same result
-I also tried TDM-GCC with the same result
-Everything worked fine before i reinstalled

I have included an image of the error in the link below:

Any idea? Ive spent 6 hours trying to solve this, so i appreciate any suggestions. I am pretty desperate by now

Try to rebuild (clean and build) your projects.

Thank you so much Jens! I have no idea why that worked, but it did Saved me a lot of frustration. I owe you a beer.

(If anyone would like to explain why i needed to clean and build, that would be great. All installation paths are the same as before the re-install)

Most likely, because your former and your actual compiler use different (incompatible) methods of error handling.
