compile failed

[summerxue1992]

The master branch code failed to compile locally. Can you confirm that it was successfully compiled? There are a number of issues with the compiled version of Solc.

Me too.
There is an error in Factory.sol line 63

assembly {
chainId := chainid <---here should be chainid()
}

But, once the line is updated as chainid(), then there will be lots of errors in this file.

have u ever solved this problem？ @xuemin007

[BIIYANG]

those contracts have ever deployed on the testchain ----- testnet.hecoinfo.com ? if yes, can you past the addresses about its contracts ? I need a stable test enviroment to test my programs.
