[issue16129] No good way to set 'PYTHONIOENCODING' when embedding python.

2013-09-16 Thread Brecht Van Lommel 

Brecht Van Lommel added the comment:

With the language summit passed some time ago, is there now a more clear 
picture of how this would fit in the initialisation process?

Any idea of what a proper implementation would look like, or is the message 
still to wait?

I tested the patch on Windows and can confirm it solves the problem for Blender.

[issue20221] #define hypot _hypot conflicts with existing definition

2014-01-23 Thread Brecht Van Lommel 

Brecht Van Lommel added the comment:

We have a similar issue in Blender (where Python is embedded), but it's 
actually causing a crash instead of only a compiler warning: 
https://developer.blender.org/T38256

The code in the Visual Studio 2013 math.h looks like this:

__inline double __CRTDECL hypot(_In_ double _X, _In_ double _Y)
{
return _hypot(_X, _Y);
}

With the #define hypot _hypot that becomes:

__inline double __CRTDECL _hypot(_In_ double _X, _In_ double _Y)
{
return _hypot(_X, _Y);
}

So you get infinite recursive calls when using hypot and the application 
crashes. The patch fix20221.patch that was attach here solves the issue.

[issue20221] #define hypot _hypot conflicts with existing definition

2014-01-28 Thread Brecht Van Lommel 

Brecht Van Lommel added the comment:

For Visual Studio 2013, here's how to redo the problem. Take this simple 
program:

#include 

int main(int argc, char **argv)
{
return (int)hypot(rand(), rand());
}

And compile it:

cl.exe test.c -I include/python3.3 lib/python33.lib /W4

c:\program files (x86)\microsoft visual studio 12.0\vc\include\math.h(566) : 
warning C4717: '_hypot' : recursive on all control paths, function will cause 
runtime stack overflow

I don't know about the conditions to get a warning in VS 2010, never tried that 
version.
