How did you even install Firefox 32 bits? We don't have such a package in Debian. It's rebranded as iceweasel, because the mozilla foundation wanted it this way (it's complicated, so I will not go into details about why, though you can search on your favorite web search engine about it). And to reply to your question: Yes, it's reasonable to spend 4 hours of your personal time on a Debian bug. Hundreds of people are spending even more time than this on a daily basis in order to improve Debian. No, it's not reasonable to report you can't run Firefox 32 bits on a 64 bits arch Debian, when really, you'd better just do: apt-get install iceweasel and use your newly installed browser in 64 bits mode...

Alexey Eromenko al4...@gmail.com writes: User error? Huh ? No ! This is a Debian Bug ! Debian clearly says: File does not exist, while in fact it DOES EXIST. This is a 100% proof of Debian bug. That's the error message that you get when the dynamic loader for a binary doesn't exist. I think that's been the case for as long as Linux has existed. It is really confusing the first time you run into it, and indeed I had to debug a problem due to that error just the other day. But it's how some rather low-level components of the system work. One could argue that it's a wishlist bug against the kernel, where I think one would have to add a new errno value just for this error so that it can be distinguished from the general ENOENT case. But, even in that case, this would have to be something changed upstream; it's not the sort of thing that Debian can carry a local patch for. Fiddling around with the error return codes of system calls in a single distribution is not a good idea. That sort of thing tends to have unforseen compatibility issues. So the short version is that, regardless, this is not a bug that Debian is going to fix specifically in Debian. If it changes upstream, obviously we and all the other distributions will pick up that change. -- Russ Allbery (r...@debian.org) http://www.eyrie.org/~eagle/ -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of unsubscribe.

It does not. However, the file the message is referring to is not the file you think it refers to: it is missing the 32-bit dynamic linker, /lib32/ld-linux.so.2 (available in the package libc6-i386), not the firefox binary itself. The message is a bit confusing, indeed, but without a dynamic linker present, it's hard to do any better. This is a 100% proof of Debian bug. You installed a 32-bit application on a 64-bit system. That will only work if you also install the 32-bit supporting libraries, including the dynamic linker. This is not a bug in Debian. And no, installing 32-bit libraries by default would be a bad idea, for a multitude of reasons. -- |8] -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of unsubscribe.

This does not mean you can't run 32bit application under a 64bit Debian installation, it's because the support is not added into default installation as the feature isn't considered stable in the Debian way. You can search for Multi-Arch for more details on this topic. You will be able to run most of the 32bit applications by installing the required 32bit libraries, and the error of File does not exist means some/all of the required 32bit libraries do not exist. I agree it is not a user-friendly error message which can cause misunderstanding, but that message should not be fixed by Debian as Russ has given the details. -- Regards, Aron Xu -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of unsubscribe.

Bug#697270: PC 32-bit programs fails to work on amd64

This does not mean you can't run 32bit application under a 64bit Debian installation, it's because the support is not added into default installation as the feature isn't considered stable in the Debian way. [...] In squeeze one could just run: apt-get install ia32-libs-gtk and most third-party i386 binaries would work. But in wheezy one must first run: dpkg --add-architecture i386 apt-get update The installer doesn't AFAIK provide even the option to do this. (The i386/amd64 installer images might at least be usable as multiarch APT sources though.) So this is a usability regression in wheezy. Further, since the ia32-libs-* metapackages are transitional, this is due to become even more difficult in jessie. I think it's a mistake to remove well-known and useful metapackages, and they should be retained. However they should probably be moved into tasksel once the installer is multiarch-aware.

Patches are welcome to make Wheezy+1 more suitable to your needs. How about changing it from a kernel bug to tasksel feature ? I recommend: tasksel to install 32-bit libraries by default, if user chooses stock Desktop (KDE/GNOME/XFCE/...). This should solve the problem for most users. This is actually a very good idea. Automatically generate the library subset of a task, teach tasksel to add the required arch tags, and make it as easy as a checkbox or a command line option to add most of the libraries you might ever need for a secondary arch. This could go a long way to make it less painful (if a _lot_ more wasteful of inodes and disk space) to deal with 32-bit non-debian applications. That said, for now, it is best to learn how to use the ldd utility to root out missing libraries for any binary. It *really* helps. -- One disk to rule them all, One disk to find them.

I guess it is bash telling you that. That's the error message that you get when the dynamic loader for a binary doesn't exist. I think that's been the case for as long as Linux has existed. That's already reported as bug #609882. I think that's asking quite a lot of bash. Wouldn't it have to open the binary and parse the ELF headers, extracting the INTERP header, in order to verify that? Does it really make sense to encode understanding of ELF binary layout formats in bash? This was discussed on Dec 26 on #-devel, a Fedora patch (http://pkgs.fedoraproject.org/cgit/bash.git/tree/bash-2.05a-interpreter.patch) was mentioned. Yes, it parses ELF headers. -- WBR, wRAR signature.asc Description: Digital signature

LSB, x32 and ARM are completely irrelevant - the important thing is to make it easy to install whatever libraries those ISVs depend on. So there are 2 subtasks here: - for i386.deb packages (that have all their deps multiarchified) the user needs only to enable M-A on their system (but that's still non-trivial); - for other binaries the user will need to find out and install deps manually, while on an i386 system they are usually already installed and on amd64 queeze they were installed because of ia32-libs (throwing all deps into one pile helps for certain problem classes). -- WBR, wRAR signature.asc Description: Digital signature
