Fatal error : pyconfig.h.

[Styvane S]

Hi,

How to fix fatal error fatal error: pyconfig.h: No such file or directory.
 #include "pyconfig.h" while compiling 'c' generated  file using
cython <filename.pyx>
Cython version 0.20.1
gcc-4.8

Thanks

Did you get a second error telling you that "Python.h" could not be found?
In that case, you need to install the Python development package (as that
error message would have told you).

This might have become a little less obvious in Cython 0.20 because it
looks for pyconfig.h before Python.h ...

Hmm, actually, no - it still #includes all header files and only then
checks for the Python version, so nothing really changed here, except that
the first header file it prints as an error is a different one. The final
error message should still be just as clear as before.

I get the same error, even though python2.7-dev is installed.

$ cython --version
Cython version 0.19

$ cython sieve3.pyx
$ ls -aFl sieve3.c

-rw-r--r-- 1 ron ron 133085 Jun 30 10:34 sieve3.c

$ gcc sieve3.c
sieve3.c:8:22: fatal error: pyconfig.h: No such file or directory
 #include "pyconfig.h"
                      ^
compilation terminated.

You're missing lots of compilation options for your gcc call:

You're missing lots of compilation options for your gcc call:

you probably want to use distutils (setup.py) to compile -- trust me on this!
