I mean which file in "hurd-19980812/exec/*.c". As long as I can read, if GZIP is defined, exec seems to be able to gunzip. So, I'd like to know which code is wrong. > That's great news!

Although I'm considering that I should rewrite it by using libbz2, I'm wondering if BSD-style license is good or not. > Note that the gzip support in exec was a quick hack for making boot > floppies, and I did it before zlib was available to provide a clean way to > reuse the gunzip code. I think your code is enough for Hurd. Although I don't want open the imcomplete patch, I put this patch to: http://www-mbi3.kuicr.kyoto-u.ac.jp/~okuji/hurd-19980812-unzip.patch.gz How to use this patch: $ tar zxf hurd-19980812.tar.gz $ gzip -cd hurd-19980812-unzip.patch.gz | patch -p0 This patch enables: * libstore can bunzip2 with `-Tbunzip2:device' option (I've not tested) * exec can bunzip2 automatically (it cannot do yet) * serverboot can gunzip and bunzip2 automatically (OK!) But, hurd-19980812 cannot be compiled, so if you want to build it really, you can use my dirty patch (VERY DIRTY!). It's available from: http://www-mbi3.kuicr.kyoto-u.ac.jp/~okuji/trash/hurd/hurd-19980812-fixed.patch.gz ---------------------------------------------------------------------- .~~.
