Comment (by frederichan):
Thank you for the report and the suggestion.
I could reproduce the error with sage 7.1.beta6. So I have tried the
following setup.py:
{{{
#!/usr/bin/env python
from sage.env import SAGE_LOCAL,SAGE_SRC
import os
from distutils.core import setup
from distutils.extension import Extension
from Cython.Build import cythonize
conf = {'CXXFLAGS' : [], 'LDFLAGS' : []}
libraries=['giac']
library_dirs=[SAGE_LOCAL+'/lib']
# in sage 6.7 cimport Integer needs ccobject.h but it was moved to
SAGE_SRC/sage/ext
# But in sage 6.8>= the function sage_include_directories was introduced
to gives the includes.
try:
# Sage >= 6.8
from sage.env import sage_include_directories
except ImportError:
# Sage < 6.8
def sage_include_directories():
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"),
]
# (on sage 6.7 without csage gives undefined symbols _signals)
libraries.append('csage')
###
include_dirs=sage_include_directories()
ext_modules=[]
ext_modules+=cythonize([Extension(
"giacpy", # name of extension
["giacpy.pyx"], # our Cython source
libraries=libraries,
library_dirs=library_dirs,
include_dirs=include_dirs,
extra_compile_args=conf["CXXFLAGS"],
extra_link_args=conf["LDFLAGS"],
language="c++")])
#cmdclass={'build_ext': build_ext}
setup(
name='giacpy',
version='0.5.2',
description='A Cython frontend to the c++ library giac. (Computer
Algebra System)',
author='Frederic Han',
author_email="[email protected]",
url='http://webusers.imj-prg.fr/~frederic.han/xcas/giacpy/',
long_description=open('README.txt').read(),
license='GPLv2 or above',
ext_modules=ext_modules
)
}}}
I can build giacpy on sage 7.1.beta6, but now older version of sage can't
because:
{{{
File "/usr/local/sage-6.9-x86_64-Linux/local/lib/python2.7/site-
packages/Cython-0.23.1-py2.7-linux-x86_64.egg/Cython/Compiler/Errors.py",
line 177, in error
raise InternalError(message)
Cython.Compiler.Errors.InternalError: Internal compiler error:
'sage/ext/interrupt.pxi' not found
}}}
