[Numpy-discussion] Numpy compilation error

[Pradeep Jha]

Hi,

I changed it. I am not getting that error anymore, but I get the following
error:
*running build
running build_py
running build_ext
building 'Cantera._cantera' extension
g++ -fno-strict-aliasing -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2
-fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i386
-mtune=generic -fasynchronous-unwind-tables -D_GNU_SOURCE -fPIC -O3 -Wall
-fPIC -fPIC -I../../build/include -Isrc -I../clib/src
-I/nfs/carv/d1/people/pradeep/src/numpy-1.3.0//include/python
-I/usr/include/python2.4 -c src/pycantera.cpp -o
build/temp.linux-i686-2.4/src/pycantera.o
src/pycantera.cpp:25:31: error: numpy/arrayobject.h: No such file or
directory
src/ctphase_methods.cpp: In function ‘PyObject* phase_getarray(PyObject*,
PyObject*)’:
src/ctphase_methods.cpp:126: error: ‘PyArrayObject’ was not declared in this
scope
src/ctphase_methods.cpp:126: error: ‘x’ was not declared in this scope
src/ctphase_methods.cpp:132: error: ‘npy_intp’ was not declared in this
scope
**************************
**************************
**************************
**************************

*The pycantera.cpp file is at*
/nfs/carv/d1/people/pradeep/cantera/Cantera/python/src*

In the file pycantera.cpp, line number 30-31-32 say:*
#ifdef HAS_NUMPY
#include "numpy/arrayobject.h"
#else*

So the error is still with NUMPY somewhere. My sys.path in Python now shows:
*
['', '/nfs/carv/d1/people/pradeep/cantera/Cantera/python/src',
'/nfs/carv/d1/people/pradeep/cantera/bin',
'/nfs/carv/d1/people/pradeep/cantera/build/bin/i686-pc-linux-gnu',
'/nfs/carv/d1/people/pradeep/cantera/Cantera/python',
'/nfs/carv/d1/people/pradeep/cantera/Cantera/python/build/lib.linux-i686-2.4/Cantera',
'/nfs/carv/d1/people/pradeep/cantera/Cantera/python/Cantera',
'/usr/lib/python24.zip', '/usr/lib/python2.4',
'/usr/lib/python2.4/plat-linux2', '/usr/lib/python2.4/lib-tk',
'/usr/lib/python2.4/lib-dynload', '/usr/lib/python2.4/site-packages',
'/usr/lib/python2.4/site-packages/Numeric',
'/usr/lib/python2.4/site-packages/gtk-2.0']

*In my bashrc file, the PATH variables are declared as follows:
*export CANTERA_ROOT=$HOME/cantera
export
PATH=$JAVA_HOME/bin/:$HOME/src/$PATH:$CANTERA_ROOT/build/bin/i686-pc-linux-gnu/:$HOME/src/pdfjam/scripts
export
PYTHONPATH=$PYTHONPATH:$CANTERA_ROOT/bin:$CANTERA_ROOT/build/bin/i686-pc-linux-gnu:$CANTERA_ROOT/Cantera/python:$CANTERA_ROOT/Cantera/python/build/lib.linux-i686-2.4/Cantera:$CANTERA_ROOT/Cantera/python/Cantera:
export Cantera_Path=$CANTERA_ROOT
*
I am not sure whats going wrong.*
*Thanks for your help.
