[xmlsec] Building xmlsec for iOs

[84.le0n]

Actually I'm not compiling for iOs but for simulator (i386 architecture) that runs on a pc, cross-compile for iOs (arm architecture) will be the next topic ;)

The only thing I want to do now is compile xmlsec using libs from sources, I don't know if all that options may conflict...have you never used all that options I use?

I don't know if I've to use the --with-lib..-src option during compiling, I've created all that libraries but I've executed "make install" too, so I don't know which option is more useful for me.

I don't understand about function name mangling...is there a separation like "underscore means private functions, otherwise are public functions" ? 
Inside source code I've not found any function starting with underscore, why the linker searches that symbols if they are not present nor called inside code? Is something related to your code or to the compilation process?

You're not familiar with compiling for iOS, but you can help me about your code ;)

Thank you for your help, and sorry for this long email ;)
