[SOLVED] 'ostream' is not a member of 'std'

[BrightBit]

Compiling my own project results in the error message:

error C2039: 'ostream' : is not a member of 'std' C:\Programming\Install\cegui\include\cegui-0\CEGUI\Base.h 183

My problem seems to be similar to this one on the Ogre forums: CEGUI 0.8.1 bugged? except that I am already using CEGUI 0.8.2.

Any ideas on what I've done wrong?

Note: My OS is Windows 7 64bit, I am using Ogre 1.9.0 and my build system is Microsoft Visual Studio 2012 Express.

[BrightBit]

I found the reason for my problem. In my build system one of the additional include directories was: "C:\InstallDir\cegui\include\cegui-0\CEGUI". However at some point during the compilation process a <cstring> header is implicitly called, that in turn looks for a "string.h" file.
The problem is that CEGUI also implements a "String.h" file (Windows doesn't care for case-sensitivity), so the <cstring> was using CEGUI's "String.h" file and this somehow caused the error message I've reported in my first post. So removing "CEGUI" from the include directory, i.e. "C:\InstallDir\cegui\include\cegui-0" solved the problem.

Here's a similar case on stackoverflow: error C2039: 'memchr' : is not a member of '`global namespace''

I remember having troubles configuring cmake for CEGUI. I wasn't able to define the install dir without the "cegui-0" subdir. Anyway, I hope this might help others.
