Bug#408341: mac-fdisk: fails to build on x86

Did you successfully read a Mac-generated partition table, or generate on that's properly recognized by a Mac? Last I looked, the partition table entries would have to be converted to host endianness before manipulating them in-core, and back-converted before writing a changed table out to disk. If you're interested in testing this, I can send you a copy of a partition table in raw format which you can dump to a blank disk (or a loopback device). My use was on a Tivo2 series PVR with a usb-storage (to ide) adapter. I was inspecting the drive for backup/restore options. This all started when I used file(1) to see it uses a mac partition table. I have etch installed on a dual booting iBook to. mac-fdisk appears to print the same partition information regardless of what machine I ran it from (x86,ppc). Tigers' disk utility sees these partitiions to (but not Linux, even with apple partition support - odd). I used the offsets provided by mac-fdisk with losetup -o offset to mount some of the ext2 file systems. Cool, tivo runs Linux. How cool is that?. Anyway, AFAIT the reading is just fine. If you want to torture test anything, you don't need a real disk if you're just comparing how the x86 compiled binary does it, and the ppc one does. Just use a few MB file to play with (it's just blocks after all...). Thanks, Scott. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Building mac-fdisk from unmodified source on any architecture save powerpc and m68k is not supposed to work, hence your FTBFS bug is not really a bug. I downgrade it to wishlist for that reason. Your guess that includes may be missing is quite right - the original code may have built on mklinux without warnings, but it's always been giving warnings on Linux. The code worked so I didn't bother. Now, the fact that the package builds (except for the pmac-fdisk-cross failure at the end, which is a consequence of ARCH being neither m68k now powerpc) and the binaries actually run is not too surprising. I would be amazed, however, if mac-fdisk does read and write correct Apple partition tables on x86 (or any other little endian architecture, for that matter).

Perhaps it's best to not have this built anymore. Michael -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Bug#408341: mac-fdisk: fails to build on x86
Package: mac-fdisk Version: mac-fdisk Severity: important Justification: fails to build from source Per #202019 it's suggested I (end user) build this from source if I want to use it on another arch. It seems to build ok, and the binaries in the package seem to work (from what I see). Lots of warnings (My hunch there is no explicit include of required #include for bzero etc etc.). See included build typescript for more details.
