Look like it can not find the cross tool 'as', and use the host's 'as' instead.

'ar' should be linked to /opt/poky/0.9+snapshot-20101219/sysroots/x86_64-pokysdk-linux/usr/bin/armv5te-poky-linux-gnueabi/arm-poky-linux-gnueabi-ar

When I modified the symbolic link manually, it can build successfully.

This also happened on ppc toolchain(test env just like discription of yi zhao).
Error met when  run "${CC} test.c -o test":

Comment 5 Liang Wang 2010-12-21 20:35:51 UTC 
This issue also occurs on mips-toolchain. The symbolic links are wrong under path /opt/poky/0.9+snapshot-20101219/sysroots/x86_64-pokysdk-linux/usr/libexec/mips-poky-linux/gcc/mips-poky-linux/4.5.1.
Comment 6 Richard Purdie 2010-12-22 06:55:31 UTC 
The pathnames are truncated at exactly 100 characters which is a limitation of tar under certain circumstances.

Inspecting the .ipk files, they're correct there but when extracted by opkg during the rootfs creation process, they are truncated. This is probably an issue with the deb_extract() which calls extract_archive() in libbb in opkg.

libbb in opkg is a very old version of libbb from busybox. There is no equivalent function in modern busybox that I can immediately see. Somehow, posix style tar files need to become supported by opkg to fix this bug.
Comment 7 Richard Purdie 2010-12-22 07:56:44 UTC 
We need this fix from opkg:
http://code.google.com/p/opkg/source/detail?spec=svn588&r=544
Comment 8 Richard Purdie 2010-12-22 10:35:22 UTC 
This should be fixed in http://git.pokylinux.org/cgit.cgi/poky/commit/?id=b1a2255b2d7f72ec2a9a196bfe5fc922e684446b. Wasn't a simple problem and a straight update of opkg didn't solve the problem, see the commit for more info.
Comment 9 Yi Zhao 2010-12-27 18:49:22 UTC 
With the arm sdk toolchain from autobuilder,
http://autobuilder.pokylinux.org/nightly/20101225-1/toolchain/x86_64/poky-eglibc-x86_64-arm-toolchain-sdk-0.9+snapshot-20101227.tar.bz2, there is no this issue.

But g77 and gfortran are empty sysmbolic links, since there are not arm-poky-linux-gnueabi-g77 and arm-poky-linux-gnueabi-gfortran. Do we need to remove these?
