The SIP specification snippet:
typedef unsigned char GLubyte; /* 1-byte unsigned */
const GLubyte * gl_error();
produces the following C++ code:
static PyObject *func_gl_error(PyObject *,PyObject *sipArgs)
{
int sipArgsParsed = 0;
{
if (sipParseArgs(&sipArgsParsed,sipArgs,""))
{
const unsigned char *sipRes;
sipRes = gl_error();
if (PyErr_Occurred())
return 0;
if (sipRes == NULL)
{
Py_INCREF(Py_None);
return Py_None;
}
return PyString_FromString(sipRes);
}
}
/* Raise an exception if the arguments couldn't be parsed. */
sipNoFunction(sipArgsParsed,sipNm__Qwt3D_gl_error);
return NULL;
}
which fails to compile with:
g++ -c -pipe -fPIC -O2 -fomit-frame-pointer -pipe -march=i586 -mcpu=pentiumpro
-Wall -W -D_REENTRANT -DHAS_NUMARRAY -DHAS_NUMERIC -DGL2PS_HAVE_ZLIB
-DQT_NO_DEBUG -DQT_THREAD_SUPPORT -I. -I/usr/include/python2.3

sip_Qwt3Dcmodule.cpp
sip_Qwt3Dcmodule.cpp: In function `PyObject* func_gl_error(PyObject*,
PyObject*)':
sip_Qwt3Dcmodule.cpp:3751: error: invalid conversion from `const unsigned
char*' to `const char*'
This pertains to the conversion in "return PyString_FromString(sipRes);"
Python-2.3.3 (don't think it matters)
