Error: Contract fails due to solidity gas limit.

• plugins: populus==2.0.1
• OS: Mac OS X

[Q] How could I increase my solidity compiler's gas limit due to this error, or another gas limit that populus reads from?

in estimate_gas -> does it exceed gas limit? When I remove some function inside my contract the error gets fixed. I guess there is a gas limit for populus to deploy the contract, is it possible to extend it? If yes how?

I too am getting same final error.
Did you find the solution ?

[avatar-lavventura]

No Sir :( @mandarvaze

[avatar-lavventura]

I am still having same error, when size of my smart contract increases ; it always crashes with this message.
