Hi,
i'm not sure if this is the correct mailing list as this is more a
question of "developing with" than "developing of" pypy.
I made some tests with cppyy and it looks promising but I have some
questions/comments.
preface: Tested with trunk and the reflex-support branch.
building with:
python translate.py -O jit --gcrootfinder=shadowstack \
targetpypystandalone.py --withmod-cppyy
64-bit linux , gcc 4.6.1
1) During build/translation there were several errors
like "undefined reference to `Reflex::Member::~Member()".
This was caused by not linking against libReflex.
With some modifications (some insertions of
(lib,"Reflex") e.g. ) in pypy/translator/tool/cbuild.py
i got a working (but see later) module. But what's the correct
way of doing the build. The "cppyy use case question" thread
mentions the problem but i didn't see the solution.
2) On importing some wrapped "c++ libs" the displayed error is very
generic. The following patch gave me some hints what's wrong .

try:
cdll = capi.c_load_dictionary(name)
except rdynload.DLOpenError, e:
- raise OperationError(space.w_RuntimeError, space.wrap(str(e)))
+ raise OperationError(space.w_RuntimeError,space.wrap(str(e.msg)))
3) playing with operators.h in pypy/module/cppyy/test/:
(m_int made public before test)
the following lines results with the expected output "10"
import cppyy
cppyy.load_reflection_info('operatorsDict.so')
number = cppyy.gbl.number
n=number(10)
print n.m_int
but if i add "virtual" to "operator==" like
virtual bool operator==(const number& n) const {return m_int ==
n.m_int; }
the output is not deterministic anymore.
This needs to be confirmed as my setup is probably not correct
(see point 1).
4) During one test i got the following error:
TypeError: none of the 1 overloaded methods succeeded. Full details :
A* B::C::methodName() =>
AttributeError: '<type '::'>' has no attribute ''
(A and C are types (classes), B is a namespace)
Generally speaking: What's the best way for debugging this problem.
Regards,
Uwe
