Setup of gin with Google App Engine

[al3xandru]

I don't seem to be able to setup gin with GAE. I understand that the trunk is Go1.3, but checking out the app_engine branch and running go install results in an error too:

go install

sounds like "github.com/gin-gonic/gin/binding" doesn't exist in your local repo?
I just tried to compile the app_engine branch and it works for me.

Can you do this:

go get -u github.com/gin-gonic/gin/binding

and then: inside the repo:

git checkout app_engine

That seemed to work, but now I see another 4 errors:

It's not new. App Engine has been rejecting app code using unkeyed
composite struct literals since early 2012. The issue is that App
Engine wants to accept correct Go code at time T, but then still be
able to recompile it at time T+n, even if the language or standard
libraries have evolved in a backward-compatible way between those two
points in time. For that reason, it is in general strongly recommended
to use keyed composite struct literals in Go code that references
types in other packages, and we enforce that recommendation on App
Engine.

Sounds like the app-engine compiler is different?

Ok! sorry. try now,I think I fixed it:

[al3xandru]

Fixed. Thanks.

[manucorporat]

ok, I am still testing it and other big changes, like the new flexible render.
I will merge it in master very soon!

[al3xandru]

Master is 1.3 and I'll have to wait for GAE to support it before being able to give it a try.
