minute: Sign up Error: Cannot use typeid with -fno-rtti up vote 6 down vote favorite I´m getting this "Cannot use typeid with -fno-rtti" when I´m trying to compile my project, I´m using an opencv framework. I googled the problem but, it seems the errors I found in internet does not have relation with my problem. I don´t know if the problem is cmake enable rtti related with the includes, the code or the compiler. Xcode is giving me the error a lot of times, but the first error is here: virtual const std::type_info& type() { return typeid(T); } c++ objective-c xcode gcc compilation share|improve this question asked Jan 4 '12 at 8:00 Gustavo 393422 for Android NDK: cppFlags += "-frtti" –Anton Savenok Aug 25 '15 at 3:50 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted It's telling you the error right in the message: if you use the no-rtti flag on the compiler, then typeid is not going to be available. Just enable RTTI; it's part of C++ after all. share|improve this answer answered Jan 4 '12 at 8:04 GManNickG 231k29346470 1 I solved this checking "GCC_ENABLE_CPP_RTTI = YES", thank you!!! –Gustavo Jan 4 '12 at 8:18 add a comment| up vote 2 down vote RTTI stands for Run Time Type Information, and typeid is an RTTI-feature. So turning off RTTI (-fno-rtti) also disables features like typeid. See http://en.wikipedia.org/wiki/RTTI for more information about RTTI in C++. share|improve this answer

However, I am facing some issues when it comes to building one of the vtk examples. I know this problem has been covered here for an objective c issue but I guess it is different for me.
