Hi - I am wondering if it is possible to build openSSL (or actually a very small portion of it) for use in an embedded ROM on an ARM11-based system. For my purpose I only need to be able to perform RSA public key decryption within the ROM. Being a ROM, I have no OS support whatsoever.
I have compiled openssl using my cross compiler. The steps I used to accomplish that: a) ./Configure linux-elf --prefix=/db/nsel/db/avalanche/progs/mv2/v6_le_uclibc --openssldir=/db/nsel/db/aval anche/progs/mv2/v6_le_uclibc/openssl no-asm no-shared b) make CC=arm_v6_le_uclibc-gcc "AR=arm_v6_le_uclibc-ar r" RANLIB=arm_v6_le_uclibc-ranlib Just for testing purposes, I put a dummy call to RSA_public_decrypt() in my ROM code, and linked with libcrypto.a. What results is a number of undefined symbols relating to OS-type calls (getpid, socket, etc...): Linking ... Error: L6218E: Undefined symbol stderr (referred from cryptlib.o). Error: L6218E: Undefined symbol getpid (referred from rand_unix.o). Error: L6218E: Undefined symbol open (referred from rand_unix.o). Error: L6218E: Undefined symbol fstat (referred from rand_unix.o). Error: L6218E: Undefined symbol close (referred from rand_unix.o). Error: L6218E: Undefined symbol getuid (referred from rand_unix.o). Error: L6218E: Undefined symbol poll (referred from rand_unix.o). Error: L6218E: Undefined symbol __errno_location (referred from rand_unix.o). Error: L6218E: Undefined symbol read (referred from rand_unix.o). Error: L6218E: Undefined symbol socket (referred from rand_egd.o). Error: L6218E: Undefined symbol connect (referred from rand_egd.o). Error: L6218E: Undefined symbol write (referred from rand_egd.o). Error: L6218E: Undefined symbol __ctype_b (referred from obj_dat.o). Error: L6218E: Undefined symbol fopen64 (referred from bss_file.o). Has anyone accomplished a similar task to what I am trying to do? I'm hoping that perhaps I made a mistake using the Configure script, and a different set of parameters will solve this problem. Thanks and regards, Greg Guyotte
