Flycheck fails to install

[jamiees2]

Installing flycheck seems to fail on OSX Yosemite. Emacs is installed under Homebrew.

Emacs version: 24.4.1 Makeinfo version: 4.8

Error:

flycheck.texi:6: warning: unrecognized encoding name `UTF-8'.
flycheck.texi:86: @pxref expected braces.
flycheck.texi:86: ` {Installation}
and @ref{Quickstart} res...' is too long for expansion; not expanded.
flycheck.texi:86: First argument to cross-reference may not be empty.
/Users/james/.emacs.d/el-get/flycheck/doc//flycheck.texi:75: Next reference to nonexistent node `Introduction' (perhaps incorrect sectioning?).

makeinfo: Removing output file `/Users/james/.emacs.d/el-get/flycheck/doc/flycheck.info' due to errors; use --force to preserve.

The error seemed to be related to #47, but this is the latest version of el-get.

How about brew link texinfo --force and try again?

[jamiees2]

Great! That works!

Thanks for all your hard work.

You are welcome. Check https://github.com/xiaohanyu/oh-my-emacs/blob/c664894e2f1c1cb0f95a9f2da88d41b00f190856/core/ome-basic.org#homebrew and https://github.com/xiaohanyu/oh-my-emacs/issues/85 for technical details, if you're interested.

I did as you said but still failed. The error info is the same with jamiees2

I did as you said but still failed. The error info is the same with jamiees2

What's the output of which texinfo and texinfo --version?

EDIT: @marksix there is no xecutable texinfo, run which makeinfo and makeinfo --version instead.

[zhangfand]

I'm running on OS X 10.10 I have installed texinfo from homebrew and link them to my path. However I don't have texinfo in my path, but I have info, makeinfo, etc. info --version return 5.2.

[jamiees2]

Same here by the way :smile:

[zhangfand]

Hi jamiees, your installation is successful now?

[jamiees2]

Yes, it is. Been running fine for 5 days.

[jamiees2]

@marksix did you take a look at #47 that I linked? Might be something there aswell.

[jamiees2]

Also, what Emacs version are you using? The default OSX one isn't compatible. What is the output of emacs -version ?

[zhangfand]

I installed emacs from homebrew and built with imagmagick, gnutls. emacs -version returned 25.0.50.1

[jamiees2]

Hmm, then I don't know :tongue:

[zhangfand]

I run emacs in gui application and installation failed. Now I run it within terminal and it succeeded. I don't understand how it happens but it's working now. Thank for your kindly help, friends.

[xiaohanyu]

This is really weird, I also run Emacs on Mac OS X 10.10 and I met no problems. I'll keep an eye on this problem.

[jamiees2]

Could it be that you forgot to run brew linkapps? The GUI version might still running the default OSX version, while emacs is the brew version.

[xiaohanyu]

Things on Mac OS X is a little complicated due to:

1. Mac has different package managers, macports/homebrew
2. Even homebrew has two ways to install emacs, one way is to install emacs by brew install emacs, and another way is to install emacs by brew cask install emacs
3. The GUI apps on Mac OS X has different $PATH with terminal(bash/zsh)

So it's not easy to track all these kind of problems in a simple way. The best way I can figure out is to provide binary distribution of oh-my-emacs, however, I still didn't get enough time to implement this.

[jamiees2]

I think that might be a little drastic. I would simply post a setup FAQ in the wiki on how to get emacs + oh-my-emacs running properly with OSX and homebrew.

[jamiees2]

I didn't know about the brew cask setup, but it might be better, as I had some issues with the Homebrew setup. I'll probably reinstall Emacs later using cask instead.

[xiaohanyu]

I do have written a section about Mac OS X installation: https://github.com/xiaohanyu/oh-my-emacs/blob/master/core/ome-basic.org#mac-os-x-compatibilities .

However, trying to build an .emacs.d from source(instead of binary, I mean, download and extract) may have some unexpected problems during installation. For instance, one man install oh-my-emacs successfully today but it may failed to install oh-my-emacs again. Oh-my-emacs depends on el-get, and el-get will download lots of things from internet, different packages have different dependencies, different package versions and may have incompatibility problems between Emacs 24.3 and 24.4 and 25.0.

So I think a better way to workaround this problem is https://github.com/xiaohanyu/oh-my-emacs/issues/99 . But I didn't got enough time to implement this for now, forgive me.

makeinfo 5.2 is working version for overwhelming the flycheck issue.(for osx Ver. 10.9.5-mavericks; emacs Version 24.5 (9.0))

To get it work:

update your texinfo package with brew update && brew install texinfo after installation complete you need to check which version of makeinfo is used.At my situataion it was still 4.8 version.(which makeinfo && makeinfo --version)

for standart homebrew installation all packeges are put under /usr/local/Cellar after brew install ...

so before moving the orginal makeinfo file go to /usr/local/Cellar and check if there is texinfo/5.2 folder or not.if it isnt there it is probably at the homebrew's user defined custom package folder.

sudo mv /usr/bin/makeinfo /usr/bin/mknfo.bkp sudo ln -s /usr/local/Cellar/texinfo/5.2/bin/make /usr/bin/makeinfo

after this, run emacs and wait it finishes it job.(oh-my-emacs installation stuck at flycheck after the changes itll continue)

meanwhile if you get any kind of "let-alist" error, install it from elpa repos: https://elpa.gnu.org/packages/let-alist.html (M-x install-package RET let-alist RET) this would solve the problem.
