Install Flycheck on spacemacs - emacs

Following this guide to configure Spacemacs as a C++ IDE, I am facing an issue when installing Flycheck.
I have followed the instructions explained here but after adding the syntax-checking instruction under dotspacemacs-configuration-layers, I have the following error when lauching spacemacs :
Error (use-package): flycheck/:init: Symbol’s function definition is void: global-flycheck-mode
I am totally new to spacemacs and emacs in general so I might have missed something obvious.
Emacs version : 27.0.50
Spacemacs version : 0.200.13
Thanks for your help,

I add additions package in this function
dotspacemacs-additional-packages '(org-trello ereader plantuml-mode elmine org-alert org-super-agenda easy-hugo ponylang-mode flycheck-pony flycheck-plantuml)
and in the (custom-set-variables add the packege to '(package-selected-packages
After restart spacemacs, all works for me, hope it will be helpful to you too.

file-error "https://melpa.org/packages/archive-contents" "Bad Request" during emacs 25.2 startup with Prelude initialization

New job, new emacs setup. I've used emacs for years but never did much customization. Running CentOS Linux 7.7 and emacs 25.2. I wanted to try the Prelude "starter kit" so I installed it. On emacs starup the Prelude init.el file (~/.emacs.d/init.el) runs and I see: error: Package ‘ag-’ is unavailable.
When I start emacs with debug enabled I see the following back trace:
Debugger entered--Lisp error: (file-error "https://melpa.org/packages/archive-contents" "Bad Request")
signal(file-error ("https://melpa.org/packages/archive-contents" "Bad Request"))
package--download-one-archive(("melpa" . "https://melpa.org/packages/") "archive-contents" nil)
package--download-and-read-archives(nil)
package-refresh-contents()
prelude-install-packages()
require(prelude-packages)
.
.
I'd appreciate any suggestions on how to resolve this.
I just ran into similar issues on a new Debian install, it looks like there are some setup issues in the default init.el.
Check your init.el against the [https://melpa.org/#/getting-started][1], it currently gives the default melpa link as: "https://melpa.org/packages/" - in my case it was http rather than https.
Then check that M-x package-list-packages works, go through the M-x package-refresh-contents , update cycle. For some reason this took a couple of attempts to work for me.

org-mode defvar-alias error when trying to use org-clock-in

I have installed org-mode Org-mode version 7.9.2+ (7.9.2+-GNU-Emacs-24-3 # /Users/jmankoff/.emacs.d/elpa/org-20131118/) using ELPA and emaics version GNU Emacs 24.3.50.1 (i386-apple-darwin11.4.2, NS apple-appkit-1138.51) of 2012-11-21 on jcmankoff.hcii.cs.cmu.edu.home
When I load org-mode and try to clock-in (using org-clock-in) I get the error byte-code: Symbol's function definition is void: org-defvaralias
I have googled around and found various suggestions (ensure that org-mode is installed in an emacs with no org-related stuff loaded; try load-library org-compat; and so on). The only thing that made a difference is that if I load-library org-compat the error changes to say that org-refresh-properties is void.
I would appreciate any suggestions on how to fix this error. Thanks.

emacs24 semantic completion

I'm trying to get semantic completions working with emacs 24 and the version of cedet that comes with it. Completions work for classes I defined in my own source file, but completion isn't working for the standard library or STL stuff Here is my emacs config:
(require 'cedet)
(require 'semantic)
(require 'semantic/ia)
(require 'semantic/bovine/gcc)
(semantic-add-system-include "/usr/include/c++/4.6.3" 'c++-mode)
(setq semantic-default-submodes
'(global-semantic-idle-scheduler-mode
global-semanticdb-minor-mode
global-semantic-idle-summary-mode
global-semantic-idle-completions-mode
global-semantic-highlight-func-mode
global-semantic-decoration-mode
global-semantic-mru-bookmark-mode))
(setq semanticdb-default-save-directory "~/.semanticdb/"
semantic-complete-inline-analyzer-idle-displayor-class 'semantic-displayor-ghost)
(semantic-mode t)
In my ~/.semanticdb directory I only see "!usr!include!c++!4.6!x86_64-linux-gnu!bits!semantic.cache", which isn't even using the version I specified in the config.
When I try M-x semantic-analyze-possible-completions on a std::list, for example, I get an error saying: "Cannot find types for std::list"
Any suggestions for how to debug this or how to fix it?
I was installing today a fresh Ubuntu 13.04 on my new SSD,
and here are my steps to configure CEDET ( I checked that it gives completions for std::list).
Basic setup
Get a fresh emacs and build it from source.
It's as easy as
./configure && make && sudo make install
Add to .emacs
(semantic-mode 1)
That's the whole setup.
Testing
Run emacs without loading anything:
emacs -q test.cc
Enter the code
#include <list>
int main() {
std::list lst;
lst.$
return 0;
}
M-x semantic-mode
with point at $, M-x semantic-ia-show-variants
Troubleshooting
If stuff doesn't work, it's likely that the semanticdb is corrupt.
Just find where it is, for me it's semanticdb-default-save-directory="~/.emacs.d/semanticdb",
and remove everything from there.
Then, when visiting a source file, call semantic-force-refresh.

I can't initialize neither swank nor clojure-jack-in

I've a problem. I've installed clojure, slime, slime-repl and elein using marmalade. Now I open my project and call elein-swank. I get this:
Starting swank..
error in process filter: slime-presentation-init-keymaps: Symbol's function definition is void: slime-define-both-key-bindings
error in process filter: Symbol's function definition is void: slime-define-both-key-bindings
and If I try clojure-jack-in I get
Debugger entered--Lisp error: (error "Could not start swank server: That's not a task. Use \"lein help\" to list all tasks.
signal(error ("Could not start swank server: That's not a task. Use \"lein help\" to list all tasks.\n"))
error("Could not start swank server: %s" "That's not a task. Use \"lein help\" to list all tasks.\n")
clojure-jack-in-sentinel(#<process swank> "exited abnormally with code 1\n")
What can I do?
I'm not sure what elein is, but I think for clojure-jack-in you need to install the swank-clojure plugin:
lein plugin install swank-clojure 1.3.3
update: as of 2013, M-x nrepl-jack-in is preferred
The jack-in method is the preferred one, but you may also try the old favorite: run
$ lein swank
from the project's main dir, and then:
M-X slime-connect
from emacs. You still need swank-clojure:
$ lein plugin install swank-clojure 1.3.3
this happened to me when i cloned someone else's clojure project from an older version. their project.clj had:
:dev-dependencies [[lein-clojars "0.5.0"]
[swank-clojure "1.2.1"]]
which is incorrect, i think, if you're using M-x clojure-jack-in. removing these lines, running lein deps and jacking in worked for me.
If you're using lein 2, then try adding {:user {:plugins [[lein-swank "1.4.4"]] } } to ~/.lein/profiles.clj. see the Plugins section of https://github.com/technomancy/leiningen/wiki/Upgrading and https://github.com/technomancy/swank-clojure

How to compile CEDET 1.0pre7 compilation for Emacs 23.1.50 on Windows?

I'm trying to compile CEDET from CVS for Emacs 23.1.50 on Windows and I've got error on "Step 6: Turning on EDE...": "defvar: Symbol's value as variable is void: cedet-menu-map". Compilation of CEDET 1.0pre6 raises the same error.
CEDET has been integrated into Emacs after 23 was released. As such, you don't need to compile CEDET for your Emacs, you just need to turn it on. In such a version of Emacs, the only difference from the install instructions from CEDET is that you don't need to load cedet.el, and you do need to turn on (semantic-mode 1) to do what cedet.el used to do.
