i have download mailcore for iphone from https://bitbucket.org/mronge/mailcore/downloads .i have try to build it shows error as
No architectures to compi
From the Getting Started documentation on the project:
IPHONE USE
MailCore has an included iPhone target, but it requires some additional compiled binaries (OpenSSL and CyrusSSL). I am unable to currently provide these, however the company Remail is offering the binaries and a compiled copy of MailCore for the iPhone. Contact Remail for more information:
mailcore@remail.com
It seems like you'd need to get those before building against the iPhone target.
