`brew install weechat` fails

[zmanji]

This is the output of brew doctor:

Warning: Setting DYLD_LIBRARY_PATH can break dynamic linking.
You should probably unset it.
Warning: /Library/Frameworks/Mono.framework detected
This can be picked up by CMake's build system and likely cause the build to
fail. You may need to move this file out of the way to compile CMake.

This is the output of brew install weechat -v can be seen at this gist.

What ruby do you have installed?

[2bits]

Thanks for adjusting your issue by making that gist. I just re-read that wiki page, and didn't realize it said all those things about mocking you. Don't take that too seriously. I figured out the real problem down below.

[sindresorhus]

I'm also having this problem. gist with required info (-v, config, doctor).

[2bits]

Thanks for the info. There were/are two issues:

1. Broken formula crafts the args incorrectly.
2. Homebrew python, not system python, contains a variable LINKFORSHARED that has an incomplete path:

$ python -c "from distutils.sysconfig import *; print(get_config_var('LINKFORSHARED'))"
-u _PyMac_Error Python.framework/Versions/2.7/Python

That command should have returned the full path into the cellar.

[2bits]

I have fixed the formula for weechat, and I will submit a pull request for it tomorrow. @sindresorhus You should probably fix those things that brew doctor mentioned. They aren't breaking weechat, but it's better if the doctor says you're raring to brew.

[adamv]

Is this only an issue against Framework Python?

[zmanji]

Since the problem I was having was related to the ruby module here is the other information requested. My $DYLD_LIBRARY_PATH has mysql set in it, I don't think it should effect how the ruby module is compiled.

Zameers-MacBook-Air:~ zmanji$ echo $DYLD_LIBRARY_PATH
/usr/local/mysql/lib:

My brew --config is located at this gist

Is there any other information that can help diagnose the problem?

[2bits]

@adamv The python issue only occurs when python is built as a framework. @zmanji We might have to adjust the formula to handle non-system Ruby if the admins say we support that. From what I've read in previous issues, Homebrew only runs correctly with the system Ruby, but let's let Adam explain that.

[2bits]

@zmanji will you please try out the formula that is linked above this post. You can do that a few different ways, but the easiest is probably

brew install -vd https://raw.github.com/2bits/homebrew/fixWeechat/Library/Formula/weechat.rb

but you could also visit the pull request 11859 and click Diff, View File, and Raw, then save that into /usr/local/Library/Formula/weechat.rb

[zmanji]

@2bits Without passing any arguments to the formula weechat compiles just fine. Enabling ruby support by using the --enable-ruby flag still fails.

[2bits]

@zmanji Thanks. Would you please run this and gist the output, thanks.

brew rm -f weechat
export VERBOSE=1
brew install -vd --enable-ruby https://raw.github.com/2bits/homebrew/fixWeechat/Library/Formula/weechat.rb

[zmanji]

The output is here.

[2bits]

@adamv Does the user have to move the system ruby into place when building software that links to Ruby? Or are they allowed to brew with Homebrew's Ruby and link to Homebrew's Ruby?

@zmanji Thanks. Can you gist this also if it exists:

/Users/zmanji/Library/Logs/Homebrew/CMakeChache.txt

There are a couple of variables in there that specify where it thinks Ruby is located.

[zmanji]

The file is here.

[jacknagel]

We allow the same flexibility with Ruby that we do with Python; the restriction that Homebrew itself uses the system Ruby is unrelated.

[2bits]

@jacknagel This looks strange doesn't it?

//Path to a program.
RUBY_EXECUTABLE:FILEPATH=/Users/zmanji/.rbenv/shims/ruby

//Path to a file.
RUBY_INCLUDE_PATH:PATH=/Library/Frameworks/MacRuby.framework/Headers

//Path to a library.
RUBY_LIBRARY:FILEPATH=/System/Library/Frameworks/ruby.framework

I'll have to figure out how to query Ruby for its environment. Any ideas?

[zmanji]

@2bits If you can't figure out the Ruby issue, could you at least submit the updated formula that actually disables plugin building by default?

[2bits]

That's exactly what my pull request 11859 does. You even said,

@2bits Without passing any arguments to the formula weechat compiles just fine.

So I'm confused.

[2bits]

@zmanji would you please try the new version of the formula I have committed. What I'm trying now is to update weechat's build scripts using the latest FindRuby.cmake from cmake-2.8.8 rather than their older module. You can do that with these commands:

brew rm -f weechat
export VERBOSE=1
brew install -v --enable-ruby https://raw.github.com/2bits/homebrew/fixWeechat/Library/Formula/weechat.rb

If that doesn't work, please gist this, which should have changed:

/Users/zmanji/Library/Logs/Homebrew/CMakeChache.txt

Thanks.

[2bits]

@sindresorhus Do you have Ruby-1.9x of some flavor installed? If so, would you please also try the commands I listed directly above this? Thanks.

[zmanji]

@2bits: Sorry about my earlier comment, I was not aware that you already submitted a pull request. That was my bad.

I have tried out your new version and again the build failed with the same error messages as before. Here I have gisted the CMakeCache here.

[2bits]

@zmanji Thanks for the new gist. On the rbenv github page, I've opened up a new issue, sstephenson/rbenv#220 , asking them to verify which of the values in your gist are accurate. Once I hear back, I'll know better how to patch weechat and how to report this bug to their developers.

I fixed the Python issue by patching weechat's FindPython.cmake so that it compiles against framework Python. I'll be adjusting my pull request, 11859, in a few minutes so at least that's done.

[zmanji]

Thanks a lot for your hard work @2bits.

[sindresorhus]

@2bits I don't think I have Ruby 1.9 installed, at least ruby -v say: ruby 1.8.7 (2010-01-10 patchlevel 249) [universal-darwin11.0]

I tried it anyway, and it installed successfully, but when I try to run weechat it doesn't exist.

-- Installing: /usr/local/Cellar/weechat/0.3.7/bin/weechat-curses

Apparently they are calling it weechat-curses. You should be able to pick it up by typing wee and hitting TAB. It seems to work, but if you could test it a bit and let us know how it goes that would help. All I did was run it and type /quit which caused it crash :-) So yea for me.

[sindresorhus]

@2bits Oh, right, that's logical... But it seems to work now ;)

Will let you now if I experience any problems.

[2bits]

We're getting no help from the rbenv people. @zmanji would you run these commands and tell me what you get:

find /System/Library/Frameworks -name libruby.dylib
find /Library/Frameworks -name libruby.dylib
find /Users/zmanji -name libruby.dylib

Thanks.

[zmanji]

Only the first command returns a result: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/libruby.dylib The other two commands do not return anything.

[2bits]

Thanks I'll work on it tomorrow.

[2bits]

Hmm, that's odd... Compare what CMake found with what you posted

RUBY_LIBRARY:FILEPATH=/System/Library/Frameworks/ruby.framework
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/libruby.dylib

CMake has a lower case ruby. I wonder if that's the problem.
