Hi all,
First off, let me say how happy I am with Cython. It enables me to
design (parts of) numpy-based algoritms that run at lightning speed! I
keep being amazed at how easy it is to create code with Cython. Keep
up the good work!
However, I just updated to version 1.4 and got a bug.
I compile my code by invoking the compiler from within Python (code
added below). I use the include_dirs option to include the Numpy
header files, and get this error message:
error: Command "gcc -mno-cygwin -O2 -Wall -Wstrict-prototypes -I.
-I"C:\Program Files
(x86)\python26\lib\site-packages\numpy\core\include" -I"C:\Program
Files (x86)\python26\include" -I"C:\Program Files (x86)\python26\PC"
-c convolution1D_.c -o build\temp.win32-2.6\Release\convolution1d_.o
-O" failed with exit status 1
Clearly, there should be a space between the "-I" and the "C:\Pro...".
Thanks,
Almar
