Look at the configure.py for PyQt5. A minimal build system would just be a
shell script that invoked sip then the C++ compiler then the linker. The
only thing you need to consider is to use the right -t flags to sip and
these can be found by introspecting current versions of PyQt.

Thanks for the pointers. I've got the example working. But now I'm
having trouble extending the example.
I've got a bunch of enums I need to make available, some of which have
overlapping names. I've been handling this by putting them in different
namespaces. But sip is complaining about that. I saw an old mailing list
question on the topic
(http://www.riverbankcomputing.com/pipermail/pyqt/2007-August/016847.html),
but no solution was posted.
My .h file is:
// Define the interface to the hello library.
#include qlabel.h
#include qwidget.h
#include qstring.h
#if defined HELLO_DLL
# define HELLO_DLLSPEC Q_DECL_EXPORT
#else
# define HELLO_DLLSPEC Q_DECL_IMPORT
#endif
namespace MyNamespace { enum MyEnum { No=0, Yes=1}; };
class HELLO_DLLSPEC Hello : public QLabel {
// This is needed by the Qt Meta-Object Compiler.
Q_OBJECT
public:
Hello(QWidget *parent = 0);
private:
// Prevent instances from being copied.
Hello(const Hello );
Hello operator=(const Hello );
};
#if !defined(Q_OS_WIN)
void setDefault(const QString def);
#endif
My .sip file is:
// Define the SIP wrapper to the hello library.
%Module hello
%Import QtGui/QtGuimod.sip
%Import QtWidgets/QtWidgetsmod.sip
%If (Qt_5_0_0 -)
namespace MyNamespace
{
%TypeHeaderCode
#include hello.h
%End
enum MyEnum { No=0, Yes=1};
};
class Hello : public QLabel {
%TypeHeaderCode
#include hello.h
%End
public:
Hello(QWidget *parent /TransferThis/ = 0);
private:
Hello(const Hello );
};
%If (!WS_WIN)
void setDefault(const QString def);
%End
%End
The compiler (linker, actually) is complaining about missing symbols:
Creating library release\hello.lib and object release\hello.exp
siphellocmodule.obj : error LNK2001: unresolved external symbol struct
_pyqt4ClassTypeDef sipTypeDef_hello_MyNamespace
(?sipTypeDef_hello_MyNamespace@@3U_pyqt4ClassTypeDef@@A)
release\hello.dll : fatal error LNK1120: 1 unresolved externals
What's the proper way to describe this to sip?
Thanks!

Hi,
Are you really compiling and linking all C++ files generated by SIP?
