Answer 1

This project appears to pre-date iOS 4, so you need to open up the .xcodeproj file for the Core Plot library itself, too. It probably also has a broken reference to an old iOS Base SDK and may need the architectures updated.

Answer 2

Try this:

Project Build Settings:

• Architectures: Standard (armv6 armv7)
• Base SDK: Latest iOS Build Active
• Architectures Only: Checked Valid
• Architectures: armv6 armv7

Delete any sub settings in the Architecture build setting.

Target Build Settings:

• Same at project settings.

Frameworks Add the SystemConfiguration.framework to your project. - Not sure why this had any impact.

Clean all targets. Build for the simulator.

Answer 3

For me it was that I had to add i386 to the VALID_ARCHS list. Odd, but it fixed my problem for simulator builds.
