compiling error :“solc error: missing code output” why?

chriseth

The interface of solidity changed before geth could react. We have to wait for an update of geth which should be available soon.
Another option is to install the 0.1.1 version of solc.

Jason

@chriseth Thank you very much

raine

How does one install v0.1.1 of solc? There are not version tags on the github repo. Thanks.

cornelis

Can someone explain the situation here in a little more detail. Why is it taking so long to fix?

tron

So solc changed API as of v0.1.2 and the two teams did not manage to perfectly coordinate the releases, so geth only supports the new API as of 1.3.0 (not released yet)
The fix is merged to the develop branch, so you can just use that with the latest solc.
Otherwise downgrade your solc to 0.1.1 or earlier.
And of course you can always use solc or the webcompiler and just use geth console to deploy.
