I was following previous one to make it. and I am stuck at this stage.

I found related article poring numpy on android here. but hard to reproduce.

and another approach could be using bento build script. but not tried.

I ackowledged that numpy on dir-825 is imposibble because of fpu and floating point calculation. So switched to x86 architecture and compiled well but don't know if its working.

succeed on building and packaging. but don't know if its working.

turns out, its not working. segmentation fault.

why don't you choose python-full rather than python-mini?

I was able to get this working with your Makefile; however I had to add two patches, one of which works in a non-standard way. I needed to edit site.cfg in the numpy sources to point to the correct python libraries. If anyone is interested, I can post this stuff and see if there is a way to get the linker to work without this work-around. At that point, I'd be happy to submit it.

PS. I changed "python-mini" to "python".

Hello, could you please post the Makefile and patch you used to compile numpy?
Thanks
Andrea

The discussion might have continued from here.
