Re: [Matplotlib-users] Compiling source and installation woes!

[Karthikesh R. <ka...@ja...>]

Hi John,

Thankx for your reply. Well, i have tried the following:

step 1: done
step 2: done
step 3: i have added '/home/karthik/usr' to the basedir which is now

basedir = {
	  'win32' : bla bla
	  'linux2':
['/usr','/home/karthik/usr','/home/karthik/usr/include']

}

Now when i try installing matplotlib, i just get :
gcc -DNDEBUG -O2 -g -pipe -march=i386 -mcpu=i686 -D_GNU_SOURCE -fPIC -fPIC
-I/usr/include -I/home/karthik/usr/include
-I/home/karthik/usr/include/python/numarray/include -Isrc -Iagg2/include
-I/usr/include/python2.2 -c src/_image.cpp -o
build/temp.linux-i686-2.2/_image.o -DNUMARRAY
src/_image.cpp:8:35: numarray/arrayobject.h: No such file or directory
src/_image.cpp: In function `PyObject* _image_fromarray(PyObject*,
PyObject*)':
src/_image.cpp:555: `PyArrayObject' undeclared (first use this function)
src/_image.cpp:555: (Each undeclared identifier is reported only once for
each
   function it appears in.)
src/_image.cpp:555: `A' undeclared (first use this function)
src/_image.cpp:561: parse error before `)' token
src/_image.cpp: In function `void init_image()':
src/_image.cpp:671: `import_array' undeclared (first use this function)
error: command 'gcc' failed with exit status 1


Ofcourse, numarray/arrayobject.h is at
/home/karthik/usr/include/python/numarray

What should i do next ?

With warm regards

karthik

PS: the array image was numeric
