Difficulty running Code::Blocks due to Standard C++ library mismatches

[Chocoboko]

Hi all,

I'm running Slackware Linux 10.2.  I am having difficulty getting Code::Blocks to run.  First, I downloaded one of those precompiled binaries (the RPM one) and got an error for saying my C++ standard library shared objects didn't match the ones Code::Blocks used.  So perhaps since I wasn't using an RPM-based Linux, that might've been the issue.  So I tried compiling Code::Blocks myself from the source from the SVN.  Lo and behold, I can't compile it for the same reason--errors in compatibility with the version of the C++ standard library used:

make[4]: *** [nativeparser.lo] Error 1

Is there a specific version of GCC I need installed?  Or is there any place I can find the needed libraries for Code::Blocks?  Anything else you'd recommend that I do.

Thank you very much for your time in reading this.

This error happens with some gcc versions, can't tell which exactly though.
Anyway search the forum (from the boards index, *not* from here) for this error. I think I saw a patch about it yesterday but I was in a hurry...

[heromyth]

It seems the patch works. However, I'm wondering what's the reason with using the code 'itsearch == 0'. I think many compiler can't support it. Maybe it's thinking of the search_scope could be NULL. If it is not that, I think my modification is still working:

Did you see it applied? No.
I plan to fix it "correctly"...

[Game_Ender]

Slightly off topic, but I didn't know you could check to see if iterators equaled NULL or 0.  Is that even standards compliant?  The standard iterators are objects with the semantics partially (or fully) matching a pointer.  I just checked and none of the standard iterators support comparison to NULL or 0, at least officially.  Of course this could all be moot if that's a custom iterator and not just a typedef of a standard one.
