error: redefinition of new

[greeniekin]

I am using codeblocks on windows.

i added "#include <SFML/Audio.hpp>" to a file now when I compile I get

I tried including System instead and same errors the errors do not make sense to me. Soon as I remove the include everything is fine.

Edit:
here is the tools.h file http://websvn.tuxfamily.org/filedetails.php?repname=tesseract%2Fmain&path=%2Fsrc%2Fshared%2Ftools.h

Which SFML file/package did you download?

[greeniekin]

I downloaded SFML2.2 from the all source code on the download page and built it my self.

Though it seems unrelated from linking as I removed the link to sfml and I still get the same error.


It seems to be this section of code in tools.h that is being a hassle

inline void *operator new(size_t, void *p) { return p; }
inline void *operator new[](size_t, void *p) { return p; }
inline void operator delete(void *, void *) {}
inline void operator delete[](void *, void *) {}

While it might seem obvious this is the problem it is not as when I remove the SFML include it all builds fine.
Deleting this section of code is not really an option either as then the rest of the code will not build.


Edit:
Never mind I worked it out.
The code snipet above was implementing a "placement new".

There is also an include for placement new which can be included by "#include <new> "

presumably SFML calls this somewhere and that is why it is redeclared.
I just deleted the above snipet and put a "#include <new>" there instead

Never had this issue with any compiler incl. the TDM 4.7.1. Thus I'm certain the error occures due to something else.
