Hi, Your first problem is that, for some reason (probably my fault) Foundation.h does not include NSRegularExpression.h. You can fix this by adding this to your program as a temporary work-around:
#import <Foundation/NSRegularExpression.h> If ICU is detected by the configure script, it will be used automatically. If not, then you may need to specify it exactly. Note that for NSRegularExpression to work exactly as documented by Apple, it MUST be compiled with blocks support. Make sure that you are using libobjc2 and have -fobjc-nonfragile-abi in your OBJCFLAGS.
