Dear GiNaC team, I have the following problem with cln library: When i try to run cln example or use it in my code, I run into the following errors: No member named 'memcpy' in namespace 'std'; did you mean 'wmemcpy'? Implicit instantiation of undefined template 'std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >' I have spent some time trying to find out what causes the problem, but did not succeed. I am using Mac os 10.14.6 and xcode 11.3.1. I tried using cln from brew distribution, as well as, compiling it from source (cln webpage). P.S. The errors arise at the moment I try to include cln path in the Xcode's "Header Search Path". Sincerely and thanks for your help, ---------------------------------------------------------------------------------------------------------------------- Oleg Popov Postdoctoral Research Associate <https://www.kaist.ac.kr/html/en/> <https://www.kaist.ac.kr/html/en/>Department of Physics, Korea Advanced Institute of Science and Technology (KAIST) 291 Daehak-ro, Yuseong-gu, Daejeon, 34141, Korea ----------------------------------------------------------------------------------------------------------------------
