Adding new class messes up project build

[mendelts]

Hey there,

I started to try code::blocks yesterday, therefore I cannot exclude user-error, but the following seems like a bug to me (It's perfectly reproducible).
Code::Blocks version 13.12, 64bit. (From the ubuntu-repos as of yesterday), OS is 64-Bit Ubuntu 14.04.

1) Create Console Application, C++, named TP (for "TestProject"), everything else as given.
* Build and run of the Hello-World Template works fine.
2) Add new class via File->new->class, named tc (for "testclass"), everything else as given, add to project, add to debug and release target.
* At this point build&run as well as rebuild are giving errors. "undefined reference to 'main'"
I thought this would be an error on my side, but the following fixes it:
3) Make any change under Project->Build Options, e.g. tick -pg flag and immediatly untick it, hit OK.
* Rebuild and build&run now work perfectly again. Without making any real changes, besides that the build options may have gotten flagged as "updated"?
Update on 3): I don't actually have to hit anything - opening Project->Build Options and hitting OK is enough to fix everything.

So all in all this means, that after creating a new class I have to do something in the build options (even if it has no effect, like checking and immedietly unchecking a box) to be able and build my project again.

I' be happy if anyone could give me some input on this one.

I've seen this bug.

When it happens, you must close the project and re-open it, or else build does not work. Even restart C::B.

Might be fixed in one of the nightly builds. I always use that.

Thanks for your reply - now I know that I'm not alone on this.

Opening the build options seems like a quicker fix to me than restarting CB or reloading the project

Strange thing is, on my desktop with a very similar setup, this bug doesn't occur.

Unable to reproduce...

On your machine where it does not work, have you tried a nightly?
