Hi,
When I try to compile U-Boot on my Arch Linux system I get the following error:
LDFLAGS="" python ./lib/libfdt/setup.py \ "-Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -include ./include/libfdt_env.h -idirafterinclude -idirafter./arch/arm/include -I./lib/libfdt -I./tools -DUSE_HOSTCC -D__KERNEL_STRICT_NAMES -D_GNU_SOURCE " lib/libfdt/fdt.c lib/libfdt/fdt_ro.c lib/libfdt/fdt_rw.c lib/libfdt/fdt_strerror.c lib/libfdt/fdt_wip.c lib/libfdt/fdt_region.c lib/libfdt/fdt_sw.c tools/libfdt_wrap.c mv _libfdt.so tools/_libfdt.so mv: cannot stat '_libfdt.so': No such file or directory make[1]: *** [tools/Makefile:124: tools/_libfdt.so] Error 1 make: *** [Makefile:1229: tools] Error 2
As far as I can tell the issue is that python defaults on my system to python 3: $ python --version Python 3.6.0
I can fix the issue by explicitly ask for python2, not sure if that is the proper way to fix this though:
diff --git a/tools/Makefile b/tools/Makefile index 1c840d7ae2..c5e422edf9 100644 --- a/tools/Makefile +++ b/tools/Makefile @@ -120,7 +120,7 @@ _libfdt.so-sharedobjs += $(LIBFDT_OBJS) libfdt:

It works, but with warnings: LDFLAGS="" python2 ./lib/libfdt/setup.py \ "-Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -include ./include/libfdt_env.h -idirafterinclude -idirafter./arch/arm/include -I./lib/libfdt -I./tools -DUSE_HOSTCC -D__KERNEL_STRICT_NAMES -D_GNU_SOURCE " lib/libfdt/fdt.c lib/libfdt/fdt_ro.c lib/libfdt/fdt_rw.c lib/libfdt/fdt_strerror.c lib/libfdt/fdt_wip.c lib/libfdt/fdt_region.c lib/libfdt/fdt_sw.c tools/libfdt_wrap.c In file included from /usr/include/python2.7/Python.h:8:0, from tools/libfdt_wrap.c:149: /usr/include/python2.7/pyconfig.h:1190:0: warning: "_POSIX_C_SOURCE" redefined #define _POSIX_C_SOURCE 200112L
