Including "sys/stat.h" from newer glibc will cause __u64 from linux uapi header to be included, causing compilation failure for u-boot tools USE_HOSTCC Remove typedef for __u64 in include/compiler.h to fix the issue. It should be safe because as of u-boot-2018.03, no ref to __u64 is found under u-boot tools/ directory Error message snippet follows HOSTCC tools/mkenvimage.o In file included from /usr/include/asm-generic/types.h:7, from /usr/include/asm/types.h:5, from /usr/include/linux/types.h:5, from /usr/include/linux/stat.h:5, from /usr/include/bits/statx.h:30, from /usr/include/sys/stat.h:446, from tools/mkenvimage.c:21: /usr/include/asm-generic/int-ll64.h:31:42: error: conflicting types for '__u64' 31 | __extension__ typedef unsigned long long __u64; | ^~~~~ In file included from <command-line>: ././include/compiler.h:69:18: note: previous declaration of '__u64' was here 69 | typedef uint64_t __u64; | ^~~~~ make[5]: *** [scripts/Makefile.host:116: tools/mkenvimage.o] Error 1 Ref: https://forum.openwrt.org/t/compile-error-19-07/44423 Ref: https://bugzilla.redhat.com/show_bug.cgi?id=1699194 Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
