Reference:

For 32 bit i386 and Raspberry Pi, you must change RADIX_BITS defined in "ibmtpm974.tar.gz/./src/Implementation.h"

Raspian is 32-bit (at least its openssl is 32-bit) while the TPM crypto defaults to 64-bit. For Raspian, change Implementation.h RADIX_BITS from 64 to 32.

#ifdef TPM_POSIX
#define  RADIX_BITS                     32

This is a sample patch that works for 32 bit system:
