I can not find ‘sys/types.h’ header files, which is usually in directory ‘/usr/include’ of a Linux system.
Where is the ‘sys’ directory with the header files (types.h., …) I need in GCC ?
The OS is Ubuntu Linux: 14.04.2 LTS. I am compiling directly on the board (no cross-compile).
The GCC compiler is the pre-installed one (GCC Ubuntu/Linaro 4.8.2-19ubuntu)
Some larger complex apps have their own copy, UE4 for example. You can install locate, then run sudo updatedb, then try locate sys/types.h to see where it exists on your system.
