[Stackless] need help with ./python-host -S -m sysconfig --generate-posix-vars

[Temp Sha]

Hi All,

I am trying to port    PyArg_ParseTupleAndKeywords(args, kwds,
"|O:tasklet", kwlist, &func)
from stackless python2.7.5 to python2.7.9  for my specific project
requirement. however I get compile time error "SystemError:
Python/getargs.c:1435: bad argument to internal function"

/root/usr/lib -Xlinker -rpath-link -Xlinker /home/temp/root/lib
-Xlinker -export-dynamic -o python \
        Modules/python.o \
        libpython2.7.a -ldl  -lutil   -lm
./python-host -S -m sysconfig --generate-posix-vars ;\
if test $? -ne 0 ; then \
    echo "generate-posix-vars failed" ; \
    rm -f ./pybuilddir.txt ; \
    exit 1 ; \
fi

This seems to be a run time err but force to check at compile somehow
with " python-host sysconfig" but not sure how. can any one help me
understanding how this checking is done
at compile time ? how can i  avoid this error ?
