Problems installing on Chrome OS

[spaceface777]

I have tried installing Linuxbrew on Chrome OS (https://goo.gl/gUFvzc) multiple times already, but it doesn't work. The installation fails at line "brew install hello && brew test hello && brew remove hello". When I run the command it gives me the error message "/bin/bash: symbol lookup error: /bin/bash: undefined symbol: rl_signal_event_hook". I have also tried running "brew update" but running any brew command gives me the same error. Chromebrew works with no problem, though. If it helps, my Chromebook info is the following: Version 52.0.2715.0 canary (64-bit) Platform 8240.0.0 (Official Build) canary-channel falco Firmware Google_Falco.4389.92.0

I don't have a Chromebook on which to test. I'd suggest contacting the author of the wiki article. @jbaum98

Please report the following:

unset LD_LIBRARY_PATH
brew config
brew doctor

Thank you. Unsetting the library path (sort of) worked. The brew command works, but the install fails. This is the terminal log:

I think that the error is here:

configure: error: in `/usr/local/linuxbrew/tmp/patchelf20160427-16900-11jaycb/patchelf-0.9':

I'm trying to replicate this probelm but I'm having some trouble. I got a similar error with an unset LD_LIBRARY_PATH but setting it to /usr/local/lib temporarily like it says in the guide made installing hello work.

[sjackman]

This error is quite odd:

==> Pouring patchelf-0.9.x86_64_linux.bottle.tar.gz
Error: No such file or directory - /usr/local/linuxbrew/Cellar/patchelf/0.9/COPYING

Please report brew gist-logs hello and also

ls -ld /usr/local/linuxbrew /usr/local/linuxbrew/Cellar

You may consider installing instead in /home/linuxbrew/.linuxbrew to make better use of bottles, which are compiled for this prefix. /usr/local/linuxbrew can also work, but can't make use of non-relocatable bottles.

[jbaum98]

Try doing brew install hello --build-from-source to stop it from using a bottle. That worked for me.

[sjackman]

What error do you get with a bottle? Please report brew remove hello && brew install hello && brew gist-logs hello

[jbaum98]

For both hello and other programs, it always gets stuck on pouring the bottle. With verbose output, it shows a bunch of patchelf commands and then it gets stuck.

The output of brew gist-logs hello was https://gist.github.com/anonymous/772a6290855ac7289db30d2f40d0e60d

[sjackman]

It just hangs after pouring the bottle? I think @DoomHammer has seen this behaviour as well. We haven't yet figured it out.

[DoomHammer]

I'll try once again with post-split repo, but the thing was simply weird. BTW: should we migrate this to linuxbrew/brew?

[sjackman]

Yep, if you're actively looking into it.

[DoomHammer]

Looks similar to Debian issue (missing /usr/bin/file) and it is something that I'd love to fix ;)

[sjackman]

@jbaum98 Could you please report the output of which -a file?

[minektur]

While the never-ending 'pouring bottle' is sitting there aparently doing nothing, the log files in ~/.cache/Homebrew/Logs/hello/ show that a ./configure was run and seemingly existed OK. If you poke around with ps and look at the process trees you can see that configure is being run multiple times. I dont know what I did, but at some point poking around, I made 'brew install hello' get un-hung and it finished. I tried to repeat it but had no success.

Forcing the build from source seems to avoid the hang. And in the chromebook default OS build there is NO file command:

$ which -a file
which: no file in (.......list of path....)

Is there a brew package that supplies a file command I could build from source and use? If not, I can probably track down the source code for 'file' and build one

Yes, there is. It's called homebrew/dupes/file-formula.

[minektur]

to answer my own question - the libmagic recipie ALMOST builds the file command, but deletes it and just keeps library :) Let me see if I can get myself a working 'file' and then retry

[minektur]

Oh - I see - building now

[minektur]

Can confirm that having a working 'file' command does not help:

chronos@localhost /usr/local/linuxbrew/Library/Formula $ which file
/usr/local/linuxbrew/bin/file
chronos@localhost /usr/local/linuxbrew/Library/Formula $ brew install hello

Already downloaded: /home/chronos/user/.cache/Homebrew/hello-2.10.x86_64_linux.bottle.tar.gz
==> Pouring hello-2.10.x86_64_linux.bottle.tar.gz

hangs "forever" - or at least a very long time. I let it set for an hour last night. Since this is installing from bottle, it shouldn't be running configure right?

chronos@localhost ~ $ ps ax | grep configure
 3302 pts/1    SN+    0:00 /bin/bash ./configure --disable-debug --disable-dependency-tracking --disable-silent-rules --prefix=/usr/local/linuxbrew/Cellar/hello/2.10

also I can confirm that building from source doesn't seem to have this problem:

chronos@localhost /usr/local/linuxbrew/Library/Formula $ time brew install --build-from-source hello
==> Downloading http://ftpmirror.gnu.org/hello/hello-2.10.tar.gz

[sjackman]

Until we fix it, I believe the file command has to live precisely at /usr/bin/file. Try

sudo ln -s `brew --prefix`/bin/file /usr/bin/

[sjackman]

@minektur Please enclose copy-and-pastes in triple back ticks. See https://help.github.com/articles/basic-writing-and-formatting-syntax/#quoting-code

[minektur]

will do, on the backticks... as for linking the file command, it is somewhat problematic on the chromebook. There are several layers of protections on the chromebook. One is to go into dev mode (then you can get shell, get root, read anything and have read-write on ~ and /usr/local - but all the OS is still read-only.

You can make /usr/bin and /bin rw but it requires remvoing another layer of protection, and disables automatic OS upgrades and a few other nice-to-have things.

In short, I can't easily make the symlink... Can you tell me which scripts are sensitive to the path of the file command so that I can potentially one-liner-sed-edit them automatically?

[minektur]

Is there an environment variable, or config file where I can force --build-from-source on ALL packages? for every install, including dependencies?

[minektur]

Also, I've done a search... can't find an open issue complaining about debian and missing /usr/bin/file - where can I go read?

[sjackman]

This issue will hopefully be fixed in the next few days. In the mean time, try change the following line: https://github.com/Linuxbrew/brew/blob/master/Library/Homebrew/keg_relocate.rb#L203

      if Utils.popen_read("/usr/bin/file", "--brief", pn).include?("text") ||

from /usr/bin/file to simply file.

[minektur]

This successfully makes installing (at least the one ) bottle pacakge(s) work for me. Thanks much.

[sjackman]

Glad to hear it! I'll commit this fix right now.
