How to install libasound2-dev 32 bit without using apt-get?

I'm working on a module with microprocessor arm A7 (32 bit) that use a Debian based distro and I'm trying to use pyaudio library. Launching the script I get the following error:

libportaudio.so.2: cannot open shared object file: No such file or directory

"sudo apt-get portaudio19" don't find the package for several reasons , so I downloaded the source code by the official web page and compiled it on hand.

Running:

./configure

I obtain at the end:

Target....................armv7l-unknown-linux-gnueabihf
C++ bindings..............no
Debug output..............no

ALSA......................no

etc. libasound2 is installed but not libasound2-dev and, again,

sudo apt-get install libasound2-dev

don't find the package. So, I'm searching for the source code but I found only 64bit version or not suitable version for my microprocessor.

Anyone know where can I find the source code of the package for a generic version 32bit?

Thanks!
