I tried to run cython from my notebook by typing these few lines
adapted from from (http://docs.cython.org/src/quickstart/build.html)
<pre>
%cython
cdef extern from "math.h":
double sin(double)
cdef double f(double x) except *:
return sin(x**2)
def integgratex(double a, double b, int N):
cdef int i
cdef double dx, s = 0
dx = (b-a)/N
for i in range (N):
s += f(a+i*dx)
return s*dx
</pre>
On two different Linux computers I get the following error message:
<pre>
/usr/bin/ld: cannot find -lstdc++
collect2: ld returned 1 exit status
error: command 'gcc' failed with exit status 1
__home_mat...16_code_sage4_spyx.c __home_mat...code_sage4_spyx.html
</pre>
When I google this error I gel only very few. Maybe someone is around
who knows this erroro message or can provide a working example.
