generating code

[Daniel]

Hi I'm trying to generate some code with the pythonqt_generator (I've got everything compiled)
and well when I have a pretty barebones typesystem file

<?xml version="1.0"?>
<typesystem package="org.clementine-player.generator">
</typesystem>

after it prints out the file name of the last header file then it segfaults

when i try to include this

<load-typesystem 
        name=":../../../../PythonQt2.0.1/generator/typesystem_core.xml"
        generate="no"/>

I get the message

Fatal error: line=6, column=16, message=Failed to parse: ':../../../../PythonQt2.0.1/generator/typesystem_core.xml'

A minimal example that I did was:

pythonqt_generator -include-paths="some include paths to find dependend files" -output-directory=. yourincludes.h  typesystem_test.txt

(include paths are useful if you include things from somewhere else)

where the typesystem looks like this:

<typesystem package="de.pythonqt.test" default-superclass="com.trolltech.qt.QtJambiObject">
    <load-typesystem name=":/trolltech/generator/typesystem_core.txt" generate="no" />
    <load-typesystem name=":/trolltech/generator/typesystem_gui.txt" generate="no" />
    <load-typesystem name=":/trolltech/generator/typesystem_sql.txt" generate="no" />
    <load-typesystem name=":/trolltech/generator/typesystem_opengl.txt" generate="no" />
    <load-typesystem name=":/trolltech/generator/typesystem_svg.txt" generate="no" />
    <load-typesystem name=":/trolltech/generator/typesystem_network.txt" generate="no" />
    <load-typesystem name=":/trolltech/generator/typesystem_xml.txt" generate="no" />
    <load-typesystem name=":/trolltech/generator/typesystem_xmlpatterns.txt" generate="no" />
    <load-typesystem name=":/trolltech/generator/typesystem_webkit.txt" generate="no" />
    <load-typesystem name=":/trolltech/generator/typesystem_phonon.txt" generate="no" />

<object-type name="SomeObject" />

</typesystem>

The important part is the generate=no for the included typesystems.
Note that the typesystems are embedded with qrc, so adressing them with : is inside the ressource system, not
the filesystem, which is why :../../sometypesystem.txt can not work.

For morre details, lookup the QtJambi example in the QtJambi Git repository, there is a generator_example which should work more or less with the pythonqt generator.

Thank's I'll try that

[Daniel]

It still just segfaults after it's parsed the header files I've tried including several different includes but can't seem to get it to work

[Florian Link]

Did you try a minimal version?

Just define some class in your header and try to wrap that for a start.

[Florian Link]

Ah and segfault means you could have a look using gdb, 8-)

[Daniel]

gdb output without debuging symbols

Program received signal SIGSEGV, Segmentation fault.
0x08065315 in Binder::visitFunctionDefinition(FunctionDefinitionAST*) ()

OK ran it on one header file seems to work but It's not generating any thing perhaps I had to many headers in it at once
thanks for you help

The parser is not really perfect, it was mainly crafted for Qt wrapping, so it might stumble on some constructs.
One thing where it failed on me was a

#define SOMEFILE "somefile.h"

#include SOMEFILE

where I had to expand the macro.

I did not modify the parser at all, it is original QtJambi code…
