Hi,
> there are a number of different 'file' programs and libtool expects
> particular output from the 'file' program that it uses.
I only have one kind of 'file' program installed, and Libtool cannot find i=
t.
Developing on Guix=E2=80=94which is a GNU project like Libtool=E2=80=94I ho=
pe to
migrate the authentication logic in Linux PAM to Guile (another GNU
project). I presently use Autotools and Libtool. [1] When running
'./configure' I get the error:
./configure: line 6750: /usr/bin/file: No such file or directory
As you can see at the bottom of this message, the issue probably
originated in Libtool, at least in part. With the help of a friend, I
found this bug.
While './configure' continues after the error, my appetite for
warnings is low due to the potential security implications of my work.
> If the 'file' encountered via PATH
> is not the same as the common one available as =E2=80=98/usr/bin/file=E2=
=80=99 on GNU
> systems, then there would be a problem.
That is a hypothetical. I have a real problem=E2=80=94for some value of
$problem. More significantly the hypothetical is my problem, and mine
alone.
If I were to use another implementation of the 'file' program,
/usr/bin/file would probably point to it. The use of the absolute path
does not ensure the program is the one Libtool expects. Moreover, it
falls outside the responsibilities of the Libtool maintainers to
curate my namespace of available executables. That is the domain of
distributions and system administrators. While the concern is valid,
it is not Libtool's problem.
As a side note, the positions here in favor of the absolute path
/usr/bin/file are only half correct. In Guix, we unequivocally believe
in absolute path names, perhaps more than most. The absolute
references allow us to have multiple versions of the same program

Hi,
> there are a number of different 'file' programs and libtool expects
> particular output from the 'file' program that it uses.
I only have one kind of 'file' program installed, and Libtool cannot find i=
t.
Developing on Guix=E2=80=94which is a GNU project like Libtool=E2=80=94I ho=
pe to
migrate the authentication logic in Linux PAM to Guile (another GNU
project). I presently use Autotools and Libtool. [1] When running
'./configure' I get the error:
./configure: line 6750: /usr/bin/file: No such file or directory
As you can see at the bottom of this message, the issue probably
originated in Libtool, at least in part. With the help of a friend, I
found this bug.
While './configure' continues after the error, my appetite for
warnings is low due to the potential security implications of my work.
> If the 'file' encountered via PATH
> is not the same as the common one available as =E2=80=98/usr/bin/file=E2=
=80=99 on GNU
> systems, then there would be a problem.
That is a hypothetical. I have a real problem=E2=80=94for some value of
$problem. More significantly the hypothetical is my problem, and mine
alone.
If I were to use another implementation of the 'file' program,
/usr/bin/file would probably point to it. The use of the absolute path
does not ensure the program is the one Libtool expects. Moreover, it
falls outside the responsibilities of the Libtool maintainers to
curate my namespace of available executables. That is the domain of
distributions and system administrators. While the concern is valid,
it is not Libtool's problem.
As a side note, the positions here in favor of the absolute path
/usr/bin/file are only half correct. In Guix, we unequivocally believe
in absolute path names, perhaps more than most. The absolute
references allow us to have multiple versions of the same program
co-installed and available at the same time. Fans of /usr/bin/file are
encouraged to explore Guix. [2] You may find happiness!
Thank you for maintaining Libtool, an old and trusted friend!

It seems to me that we are looking farther than needed; unless we have good reasons not to (which we do not seem to have), it seems reasonable to assume 'file' to be correctly working; if the user install a 'file' command on their PATH which behaves differently than the traditional 'file' utility, they can only blame themselves for problems. > A simple approach would be to use /usr/bin/file if is available, or > otherwise use the first 'file' found in the executable search path. > This avoids the need for re-testing on exotic systems and does not > substantially increase the level of risk. For the non-FHS package managers such as Guix/Nix, that are able to run on top of any GNU/Linux distribution, that would be sub-optimal as the command would be used from the host instead of from the user's PATH; e.g. if you 'guix install file', file wouldn't be used from Guix but from the host distribution instead. I hope that helps to understand the rationale for behind preferring PATH to hard coded locations. Maxim

Ludovic being the creator of GNU Guix, a functional package manager/distribution, I rather suspect that it comes from the fact that Guix does not follow the Linux Foundation's File Hierarchy Standard (for a good reason -- to be able to refer to each input unambiguously based on their corresponding hash). On those systems, the only sane way to find commands is to use the PATH. HTH, Maxim

I suspect this has something to do with merging /usr/bin and /bin coupled with some purist attempt to get rid of the compatibility symlink from one to the other. But that's just a guess.

Any arbitrary "file" a user may have on $PATH. Actually, in Fedora's packaging, we generally prefer absolute paths over plain "file names", to avoid malfunctions from arbitrary stuff people may have laying around on $PATH. > Besides, relying on file names to identify programs seems fragile: Correct. Trying to utilize "file"'s output to distinguish file types has a long history of breaking things and not being robust. Ralf

Yes, it is fragile but it is more likely to encounter a wrong program named 'file' in the path than to encounter a wrong /usr/bin/file program. > If there’s a concrete risk of confusion with a same-named program, > perhaps the most robust thing to do would be to try, say, ‘file > --version’ and search for some distinguishing pattern in the output. What would we do if 'file' did not respond appropriately to a --version argument? A simple approach would be to use /usr/bin/file if is available, or otherwise use the first 'file' found in the executable search path. This avoids the need for re-testing on exotic systems and does not substantially increase the level of risk.

Were you able to re-test on all of the impacted platforms? The reason for the hard-coded path is because there are a number of different 'file' programs and libtool expects particular output from the 'file' program that it uses. If the 'file' encountered via PATH is not the same as the common one available as ‘/usr/bin/file’ on GNU systems, then there would be a problem.

Hello,
The patch below changes occurrences of =E2=80=98/usr/bin/file=E2=80=99 to j=
ust =E2=80=98file=E2=80=99.
The impetus is that on systems using GNU Guix, NixOS, GoboLinux, and
others, the =E2=80=98file=E2=80=99 command is not available as /usr/bin/fil=
e, so it must
instead be taken from $PATH.
(I conservatively left =E2=80=98/usr/bin/file=E2=80=99 for more centralized=
systems such
as BSD, IRIX, etc. where it=E2=80=99s more likely to be a valid command.)
WDYT?
Ludo=E2=80=99.
