TYPO3 Core

Patch set 2 for branch TYPO3_6-2 of project Packages/TYPO3.CMS has been pushed to the review server.
It is available at http://review.typo3.org/43184

Your setup will work if /Users/$user/Sites/TYPO3/Packages/Libraries/ is your vendor-dir. Have you tried that? For 6.2 no other layout is supported.

(Resolving the path you mentioned gives /Users/$user/Sites/TYPO3/Packages/Libraries/autoload.php)

My folder structure looks like

.
├── Packages
├── composer.json
├── composer.lock
├── fileadmin
├── index.php -> typo3_src/index.php
├── typo3 -> typo3_src/typo3
├── typo3_src -> /Users/sok/Sites/TYPO3/6-2
├── typo3cms
├── typo3conf
├── typo3temp
└── uploads

What's the full path to this root directory here? Again, your vendor-dir must be /Users/$user/Sites/TYPO3/Packages/Libraries/autoload.php in this setup for TYPO3 to find it.

The core is located at

/Users/$user/Sites/TYPO3/6-2

/Users/$user/Sites/$project/dev/htdocs

My vendor dir in comoser.json is

"vendor-dir": "Packages/Libraries"

$ composer install

/Users/$user/Sites/$project/dev/htdocs/Packages/Libraries

The composer packages are part of my installation and not of the core as you suggest.

This will work if typo3_src will locate in the webroot and not somewhere outside.
