Function argument cannot have C name specification

[ptao]

Hi,

I'm having trouble with the following function:

namespace TWSComManagerLib
{
class TWSComManager
{
public:
static std::string GetConfigParam(std::string sKey);
}
}


Here's my pxd:

cdef extern from "string" namespace "std":
cdef cppclass string:
char *c_str()
int length()

# Hack for static member functions
cdef extern from "libtwscom/TwsComManager.h" namespace
"TWSComManagerLib::TWSComManager":
string GetConfigParam(string sKey)

This gets the following error:

Error converting Pyrex file to C:
------------------------------------------------------------
...

# Hack for static member functions
cdef extern from "libtwscom/TwsComManager.h" namespace
"TWSComManagerLib::TWSComManager":
int TWSCount
TWSComManager *Instance()
string GetConfigParam(string sKey)
^
------------------------------------------------------------

.../libtwscom/cTwsCom.pxd:137:25: Function argument cannot have C name
specification

I have non-static functions which take string arguments which work
just fine. The only problem I'm having is with this function.

This is a serious blocker on a project I'm working on, so any help is
greatly appreciated.

Thanks.

I don't think it has been fixed :(
I still have the same problem. I couldn't understand the code of Cython enough to fix it myself, so I had no other choice to wrap my namespace function with a simple function. Something like:

int    myFunc__myNamespace(int a, int b)
{
   return myNamespace::myFunc(a, b);
}

And wrap this with Cython.

No. For the moment most efforts are focused on getting 0.13 out the
door (a.k.a. sorting out the issues with some heisenbug in Sage). The
new C++ support is really cool, but still quite unfinished.

That should work well.
