Install the opensc on UClinux

Hi Anri,

opensc and libtool rely on the autoconf 'configure' scripts;
as long as 
the 'configure' script detects that dynamic linking is not
supported on 
uclinux you should be fine.
however, what do you intend to do with engine-pkcs11 without
dynamic lib 
support? engine-pkcs11 is primarily intended to be loaded as
a shared 
library inside an openssl session...

HTH,

JJK

Hi Anri,

your only "way out" that I see is to link
**everything** statically, 
including a rebuild of openssl with the engine-pkcs11
library in place. 
Especially this last part will be particularly tricky. I've
built 
engine-pkcs11.so with a statically linked opensc-pkcs11.so
without any 
problems - IIRC it was just a matter of
- building opensc-pkcs11
- removing the opensc-pkcs11.so file (so that only the .a
remains)
- linking engine-pkcs11.so against opensc-pkcs11

HTH,

Hi Anri,

this is getting more complicated with each post... sounds
like you want 
to port all of pcscd + opensc to uclinux... I'd start out
with pcscd 
first, and I am pretty sure you'll run into plenty of
trouble. Yes , 
pcscd uses dlopen to load external libraries and no, I don't
know of any 
other card readers for Linux.

cheers,

JJK

Maybe openct can work for you.

Jan is right, if openssl should be able to use the card you
have a
lot of work to do, to include all of opensc into openssl.

I suggest you investigate the openssl mailing list, first
search the
archives then explain your situation and see if they have
any
suggestions or experience with openssl on uclibc.

Not always. openct has native drivers for several cards, but
it can
also be made to use pcscd.

No, openct also supports several serial readers.

Please have a look at http://www.open
sc-project.org/openct/
