php - Symfony/Less @icon-font-path is undefined in glyphicons.less -

i use symfony 2.4 , installed bundle mopabootstrap.

less say: nameerror: variable @icon-font-path undefined in glyphicons.less on line 13, column 8. it's mopabootstrap file.

i extend 'mopabootstrapbundle::base_initializr.html.twig'. have no particular code, it's new project.

less work great code, except bootstrap glyphicons file.

any idea ?

edit: there open issue there if have ideas: https://github.com/phiamo/mopabootstrapbundle/issues/839#issuecomment-39893655

i removed 'apply_to: ".less$"' in config.yml , added less filter twig tags. assetic:dump --watch seems work fine.

config.yml

assetic: debug:          %kernel.debug% use_controller: false filters:     less:         node:       /usr/local/bin/node         node_paths: [/usr/local/lib/node, /usr/local/lib/node_modules]         apply_to: "\.less$" <<<<< remove line

base.html.twig

{% stylesheets     '@mopabootstrapbundle/resources/public/less/mopabootstrapbundle.less'     filter='less' <<<<< add line %}     <link href="{{ asset_url }}" type="text/css" rel="stylesheet" media="screen" /> {% endstylesheets %}
