[xmlsec] Building xmlsec for iOs

[84.le0n]

Hi aleksey,
I'm trying again to compile for iOS but I need a check about a symbol I've found.
I'm trying to concentrate and resolve the problem on _xmlSecOpenSSLAppInit that is undefined in apps/crypto.c (as many other in this file) but I've found that this symbol is defined in another header.

In fact I've noticed that _xmlSecOpenSSLAppInit is undefined inside 
src/openssl/libxmlsec1_openssl_la-crypto.o 
and is undefined in 
apps/crypto.o (that stops building) 
but is defined inside 
src/openssl/libxmlsec1_openssl_la-apps.o !

Can you check if this is the normal state of symbols definition in your correct builds ?

Maybe makefile rules doesn't have the needed -l ? Could it depend on configure switch?

Thank you!
