Hi Jay,
Thanks for your reply.
Our requirement is as follows
1. only using openssl for authenticaion and a key wrap algorithm. No encryption is needed.
2. For MAC alogorithm, we need to use M_SHA1 / M_SHA256
For key wrap algo, we need to use AES 128 or AES 256 algo.
Following are the steps we followed
1. As we have eCOS platform, we just integrated the openssl files (1.0.1g) and added to them to our makefile to build them (only .c and .h files)
2 In our applicatoin we call the openssl functions to above two functions from the openssl.
key wrap algorithm to decrupt the session key which is received from the master. AES_set_decrypt_key, AES_unwrap_key
MAC algo to generate a mac value for a message (HMAC(), EVP_sha1(), EVP_sha256())
3. But during the linking stage we are getting the errors as ""undefined reference to a function "
Example":
openssl/openssl101g/crypto/engine/tb_rand.o(.text.ENGINE_get_default_RAND+0x8): In function `ENGINE_get_default_RAND': undefined reference to `engine_table_select'
4. Not able to figure out if there is any common setting file (to configure openssl ) so that we can enable /disable some features and services.
We tried doing the method as your had suggested. But it seems that there is not much effect for the declaration of eCos
Request to please let us know what mistake we are making, or we have missed out any configuration.
Regards,
SSK

Subject: Re: Using Openssl for eCOS platform
I have used the following snippet (along with some others) in the e_os.h header file:
# if defined(__ECOS)
# define __INITIAL_POINTER_SIZE 0
# define GETPID_IS_MEANINGLESS
# define NO_CHMOD
# define NO_SYSLOG
# define HAVE_LONG_LONG 1
# define HAVE_LONG_DOUBLE 1
# define OPENSSL_THREADS
# undef DEVRANDOM_EGD
# endif
The GETPID_IS_MEANINGLESS might work for you.

Hi,
Best way to do is to modify e_os.h header file.
This file has to do with OS specific changes.
Something like
#ifdef ECOS
#define getpid ecos_task_id_fn
#endif
ecos_task_id_fn is a placed holder, find out actual function name to get process ID.
GetThreadID is the function in NETWARE.

Hi, I am using openssl on a n eCOS platform. I need only the secure authentication (no encryption needed). I integrated the openssl source code with my application. When I trying to build, I am getting some linking errors. :undefined reference to 'getpid' :undefined reference to 'RANDpoll' I am trying to find how to enable or disable the macros (switches to enable or disable a feature/service). But it seems that openssl.conf is generated from some utitlity program and from a file opensslconf.h.in<http://opensslconf.h.in> Pl. anyone suggest how to configure. Regards, SSK
