[OpenWrt-Devel] OpenWRT built on OpenSuSE (x86_64) fails

[Luiz Angelo Daros de Luca]

Hello,

I'm trying to compile OpenWRT on an OpenSuSE 13.1 x86_64 targeting x86
generic (default config). However, I'm getting a strange behavior. In thunk
and BB, some packages that compiles for host machine are having problems
with pointer size:

openwrt/trunk/build_dir/host/grub-2.02~beta2 $ arch
x86_64
openwrt/trunk/build_dir/host/grub-2.02~beta2 $ grep SIZEOF_VOID_P config*h
config.h:#define BUILD_SIZEOF_VOID_P 8
*config-util.h:#define SIZEOF_VOID_P 4*

SIZEOF_VOID_P in host should be 8 if compiled for x86_64. And I get x86_64
binaries:

$ file build_dir/host/grub-2.02~beta2/grub-install
build_dir/host/grub-2.02~beta2/grub-install: *ELF 64-bit* LSB executable,
x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for
GNU/Linux 2.6.32, BuildID[sha1]=5082730f329f77b19783a7d9f6128bc6f3a45b10,
not stripped

I also get related warnings:

./include/grub/crypto.h:286:9: warning: cast from pointer to integer of
different size [-Wpointer-to-int-cast]
     || ((grub_addr_t) outptr & (sizeof (grub_uint64_t) - 1))))

As it compiles x86_64 program considering a pointer size from 32-bit,
programs did not work.

If I run the configure manually (with same args and PATH), the problem is
not present:

trunk/build_dir/host/grub-2.02~beta2.new $ grep SIZEOF_VOID_P config*h
config.h:#define BUILD_SIZEOF_VOID_P 8
*config-util.h:#define SIZEOF_VOID_P 8*

I isolated the problem to be the usage of
CONFIG_SITE=/home/REDETRESC/luizluca/prog-local/openwrt/trunk/include/site/i486-openwrt-linux-uclibc

Is the usage of i486-openwrt-linux-uclibc expected? Should it be
x86_64-openwrt-linux-uclibc for host compile?

In Ubuntu, I get no problem.

In AA, I had no problem. The configure args from grub in AA and grub2 from
BB/trunk have some differences. In AA, I have a single
--target=x86_64-suse-linux but grub binaries are 32bit (but other
host/compile packages are 64-bit).

In BB/trunk I have duplicated --target= arg in configure. The first is
--target=x86_64-suse-linux but the second one is
--target=i486-openwrt-linux-uclibc. This might trigger cross compiling.

This is host configure in BB/trunk:

(cd
/home/REDETRESC/luizluca/prog-local/openwrt/trunk/build_dir/host/grub-2.02~beta2/;
if [ -x configure ]; then cp -fpR
/home/REDETRESC/luizluca/prog-local/openwrt/trunk/scripts/config.{guess,sub}

In Makefile, I have:

package/boot/grub2/Makefile:
 54 HOST_CONFIGURE_ARGS += \
 55     --target=$(REAL_GNU_TARGET_NAME) \

If I remove target, it does not change.

Do you guys have any clue?
