Mark `bc` as a package dependency #2974

Tuetuopay · 2016-04-25T15:46:08Z

On some systems, the bc utility is not present in the default install, making the math command unusable. This has been tested on CentOS 7 Minimal and Debian 7, where fish was installed through the package manager, as explained here.

Reproduction Steps:

Install fish using the steps given here
Do any kind of math, e.g. math 2+2

Expected behavior:

We should get the expected math output, as stated in the docs.

tuetuopay@server ~> math 2+2
4

Observed behavior:

The math command fails saying the bc is unknown.

tuetuopay@server ~> math 2+2
env: bc: No such file or directory

(the error message might be a little off, as I translated it from French)

Additional information:

Clean CentOS 7 Minimal install. The problem was fixed by installing the bc package with yum.

Fish version: 2.2.0

Operating system: CentOS 7 Minimal and Debian 7, and fish was installed from the repositories from OpenSUSE following this guide (linked from fish's homepage).

Terminal or terminal emulator: Cygwin

The text was updated successfully, but these errors were encountered:

isn't it bc not gc?

Tuetuopay · 2016-04-25T22:08:56Z

Ooops yeah, editing

I can't reproduce the error that you describe. I think the problem is in your OS.

First, fish.rpm depends on 'bc':

$ rpm -q --qf "%{DISTRIBUTION}" --nosignature -R -p fish-2.2.0-3.2.x86_64.rpm 
shells:fish:release:2 / CentOS_7/bin/sh
/bin/sh
/usr/bin/env
/usr/bin/pkg-config
bc
config(fish) = 2.2.0-3.2
libc.so.6()(64bit)
...

How did you install the package without dependencies? Yum must install them.

Second. I installed CentOS-7-x86_64-Minimal-1511.iso, download a repo-file with:

[root@localhost ~]# cd /etc/yum.repos.d
[root@localhost ~]# wget http://download.opensuse.org/repositories/shell:fish:release:2/CentOS_7/shells:fish:release:2.repo

Then install fish-shell:

[root@localhost yum.repos.d]# yum install fish

On CentOS, I did the same as you (wget in /etc/yum.repos.d then yum install fish), but bc is not a dependency.

On debian, there indeed is a problem with my system, as bc is a dependency (according to apt-cache showpkg fish) but it didn't get installed o_O

Tuetuopay · 2016-04-26T10:40:09Z

I just found the root cause on centos : yum installed the package from the epel repository, and not from suse repo.

So I guess the culprits are the epel maintainers and not the fish maintainers :/

isudak · 2016-04-26T10:46:20Z

@Tuetuopay Good for you! Is it time to close the issue?

Tuetuopay · 2016-04-26T10:48:22Z

I guess so, unless the package in the epel repo is maintained by the fish maintainers

isudak · 2016-04-26T11:03:03Z

Hmm.. According to the changelog (https://dl.fedoraproject.org/pub/epel/7/SRPMS/f/fish-2.2.0-7.el7.src.rpm):

%changelog

Sat Jan 02 2016 Oliver Haessler oliver@redhat.com - 2.2.0-7

included patch directly into the spec file

added new patch for using python3.4 on EPEL 7

excluded ppc64le as the fish_tests fail for this arch

the maintainer is from RedHat...

Tuetuopay · 2016-04-26T11:04:12Z

Yup, filing an issue in their bugzilla atm, the issue can be closed.

zanchey · 2016-04-26T13:18:04Z

Yep - please take this up with downstream.

andrew-schulman · 2016-10-31T15:54:31Z

In Cygwin I added REQUIRES="bc" to the Cygport build script, to enforce the dependency on bc.

See fish-shell/fish-shell#2974 This will only fail at runtime in some autocomplete commands, if the dependency is not installed.
