We (WR) had code that would produce a zip format, but that stopped working a few releases ago when the archive chaining was reworked.. We've not yet resurrected the code for the .zip generation but probably will in the next few months. > __ __ > > 2) However, when I use 7ZIP to extract it on my Windows host (which is > recommended for XY files), I get several fatal issues.____ > > __ __ > > (a) I get more than a hundred errors “Can not create symbolic link: > Access > is denied”. ____ This is odd. In the past 7ZIP (when not the admin) would create either copies or 'shortcuts' instead of actual symbolic links. It sounds like something has changed in 7zip. > __ __ > > While I do not care about the ones for the bin tools in the sysroot, I do > care that most of the cross toolchain EXE files are thusly broken, plus > many > of the libraries and header files in the sysroot.____ > > __ __ > > Am I missing a step?____ > > __ __ > > If I in fact extract this file on my Linux host, I can directly see that > it > is full of symlinks! Why are there symlinks in a Windows-specific > tarball?____ Often I've extracted it on a linux machine, and then uses zip to recompress it. (You still need to use 7zip to extract because of the long pathnames that blow up winzip.) > __ __ > > (b) If I attempt to build a simple C file from the shell in the SDK > environment, I either get a silent failure (for the 32-bit toolchain) or a > blatant error as per:____ What version of windows are you using? The last time I tested this (Rocko) it was working properly still, but I tested with Win 7. So it's possible that something more recent has broken it. I'm not sure if I'll have time today to retry this with Rocko, but I'll see if I can. --Mark -- _______________________________________________ yocto mailing list firstname.lastname@example.org https://lists.yoctoproject.org/listinfo/yocto
