Comment (by frederichan):
Sorry for the delay but I still have problems with trac12375. I have
tried to isolate the problem:
(can you reproduce it?)
setup.py:
{{{
#!/usr/bin/env sage -python
from sage.env import *
import os
###
try:
# Sage >= 6.8
from sage.env import sage_include_directories
except ImportError:
# Sage < 6.8
def sage_include_directories(source=True):
return [
os.path.join(SAGE_LOCAL, "include"),
os.path.join(SAGE_LOCAL, "include", "csage"),
os.path.join(SAGE_SRC),
os.path.join(SAGE_SRC, "sage", "ext"),
]
###
from distutils.core import setup
from distutils.extension import Extension
cmdclass = { }
ext_modules = [ ]
include_dirs=sage_include_directories(True)
from Cython.Distutils import build_ext
ext_modules+=[Extension(
"giacpy", # name of extension
["giacpy.pyx"], # our Cython source
include_dirs=include_dirs,
language="c++")]
cmdclass={'build_ext': build_ext}
setup(
ext_modules=ext_modules,
cmdclass=cmdclass
)
}}}
and giacpy.pyx
{{{
from sage.rings.integer cimport Integer
from sage.env import * ##without this line it builts
include 'sage/ext/interrupt.pxi'
include 'sage/ext/stdsage.pxi'
}}}
gives:
{{{
giacpy.cpp: In function ‘int __pyx_import_star_set(PyObject*, PyObject*,
char*)’:
giacpy.cpp:3635:55: error: ‘__pyx_convert__from_py_sage_signals_t’ was not
declared in this scope
_signals = __pyx_convert__from_py_sage_signals_t(o); if
(PyErr_Occurred()) {__pyx_filename = __pyx_f[3]; __pyx_lineno = 45;
__pyx_clineno = __LINE__; goto __pyx_L2_error;};
}}}
