Re: [Pharo-dev] How to merge code in Pharo3.0

Hi Hans Peter, usually I click on the package version and press merge. When there is a conflict I select the item and decide which one I keep either the incoming or the other. This is not working for you? May be we got a glitch. Stef On 11/11/14 09:34, Holger Hans Peter Freyther wrote: > Hi, > > I am sorry if that is the wrong mailinglist.

The build fails because Camilloâs repo is gone from smalltalkhub. The same is true for all the Pharo related stuff on his github account. Iâve got it working locally with a bit of symlinking. If Esteban is ok with it, Iâll do a quick fix to get the build working again.
