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. 11281 6 richard.purdie 2010-12-22 06:55:31 +0000 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. 11282 7 richard.purdie 2010-12-22 07:56:44 +0000 We need this fix from opkg: http://code.google.com/p/opkg/source/detail?spec=svn588&r=544 11284 8 richard.purdie 2010-12-22 10:35:22 +0000 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. 11331 9 yi.zhao 2010-12-27 18:49:22 +0000 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.
