Hi have this error when try gmake in the Server source folder :

clang++-devel -Wall -O2 -pipe -mtune=i686 -g -I../include -c utils.c
clang++: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-Wdeprecated]

thats is the version of gcc in the virtualbox machine

gcc -v

Sorry for the post but I have already solved the problem, just go to each file cited by the compiler and delete the word register which is deprecated, once this is done the compilation is successful

Hi, just remove "register"
