# Example for armhf sudo apt install gcc-arm-linux-gnueabihf libc6-dev-armhf-cross Manually create an empty stub file:
| Cause | Explanation | |-------|-------------| | | The header wasn’t introduced yet. | | Missing headers | Incomplete installation of libc6-dev or kernel headers. | | Wrong include path | The compiler is searching in incorrect directories (e.g., stale sysroot). | | Cross-compilation misconfiguration | The sysroot lacks the necessary 32-bit time headers. | | Non-glibc environment | Alpine/musl doesn’t have this glibc-specific internal header. | How to fix it 1. Update glibc (if possible) On Debian/Ubuntu: bits timesize-32.h no such file or directory
If you still face the issue, check your compiler command for -I flags that might be overriding default include paths. Running gcc -v can show where it’s searching for headers. # Example for armhf sudo apt install gcc-arm-linux-gnueabihf
#include <time.h> #include <sys/time.h> When cross-compiling, ensure your sysroot contains full glibc headers matching the target: | | Cross-compilation misconfiguration | The sysroot lacks
sudo apt update sudo apt install libc6-dev On RHEL/CentOS/Fedora:
#include <bits/timesize-32.h> Use standard headers:
