Hello all,

I'm struggling with the OpenWRT compilation with SDK and toolchain enabled. I've done lots of fresh compilations (~3 hours on my PC) until I've found a problem - it's a SDK compilation. I can choose it in 'make menuconfig' or do 'make target/sdk/install' I still get same errors. The error is as follows:

cat /home/darius/build/openwrt/trunk/feeds.conf.default \

The problematic line is I think this:

tar cfj /home/darius/build/openwrt/trunk/bin/ar71xx/OpenWrt-SDK-ar71xx-for-Linux-x86_64-gcc-4.6-linaro_uClibc-0.9.33.2.tar.bz2 OpenWrt-SDK-ar71xx-for-Linux-x86_64-gcc-4.6-linaro_uClibc-0.9.33.2;

There is no such path as /home/darius/build/openwrt/trunk/build_dir/target-mips_r2_uClibc-0.9.33.2/OpenWrt-SDK-ar71xx-for-Linux-x86_64-gcc-4.6-linaro_uClibc-0.9.33.2 so I think thats why I get permission denied error. I just can't understand how can I fix this error and successfuly compile SDK. Please help me with some advices.
By the way, despite the error, I still get firmware images produced.

Ok, I've made some investigation and found line in Makefile of SDK which causes problems:

$(TAR) -cf - -C $(TOPDIR) \
        $(foreach exclude,$(EXCLUDE_DIRS),--exclude="$(exclude)") \
        --exclude="staging_dir/$(ARCH)" \
        staging_dir/host staging_dir/target-$(ARCH)$(ARCH_SUFFIX)_$(LIBC)-$(LIBCV)$(if $(CONFIG_arm),_eabi) \
        staging_dir/toolchain-$(ARCH)$(ARCH_SUFFIX)_gcc-$(GCCV)_$(LIBC)-$(LIBCV)$(if $(CONFIG_arm),_eabi) | \
        $(TAR) -xf - -C $(SDK_BUILD_DIR)

This line compress some contents on the fly and then decompress to different folder. And the problem is that after decompression some of the files are 0 bytes size with permissions set to none. I've done that command manually and surprisingly everytime different files are set to 0 size and permissions none.
Could anyone please do 'make target/sdk/install V=99' and post result here. Also its interesting what is tar version in your case. Mine is 1.26. Now I'm really lost, if this is caused by tar or by buildroot. I do not have any other problems when building. Only this one.

I've found the problem. It was TAR version 1.26 on my 64-bit machine which was causing the problems. Interesting thing is that there is no problems on 32-bit machine with TAR version 1.26. So my solution was to downgrade TAR to version 1.23 on 64-bit machine. Now everything is working fine.
Could anyone please report here the status on 64-bit system with TAR 1.26. Is anyone using that combination ?

Works for me.
64bit Ubuntu 12.04 in Virtualbox, tar 1.26
A 75 MB sized SDK file gets created with 'make target/sdk/install' without any complaints.

Thank you very much for information. Only difference I can see is linux kernel version:
darius@hp6715b:~$ uname -a
Linux hp6715b 3.2.0-3-amd64 #1 SMP Thu Jun 28 09:07:26 UTC 2012 x86_64 GNU/Linux

I have amd64 revision while yours is generic. Maybe this could be an issue ? It would be nice to hear from other users running amd64.

The discussion might have continued from here.
