Solidity is a statically typed, contract-oriented, high-level language for implementing smart contracts on the Ethereum platform.
Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on the Ethereum Virtual Machine. Smart contracts are programs that are executed inside a peer-to-peer network where nobody has special authority over the execution, and thus they allow to implement tokens of value, ownership, voting and other kinds of logics.
When deploying contracts, you should use the latest released version of Solidity. This is because breaking changes as well as new features and bug fixes are introduced regularly. We currently use a 0.x version number to indicate this fast pace of change.
Instructions about how to build and install the Solidity compiler can be found in the Solidity documentation.
Here is instructions about how to build and install the Solidity compiler.
For macOS, ensure that you have the latest version of Xcode installed. This contains the Clang C++ compiler, the Xcode IDE and other Apple development tools which are required for building C++ applications on OS X. If you are installing Xcode for the first time, or have just installed a new version then you will need to agree to the license before you can do command-line builds:
sudo xcodebuild -license accept
Our OS X builds require you to install the Homebrew package manager for installing external dependencies.
Here is the list of components that should be installed in Windows:
git
CMake
Visual Studio 2017 Build Tools or Visual Studio 2017
# visual studio 2017 Build Tools should include:
Visual Studio C++ core features
VC++ 2017 v141 toolset (x86,x64)
Windows Universal CRT SDK
Windows 8.1 SDK
C++/CLI support
To clone the source code, execute the following command:
git clone --recursive https://github.com/tronprotocol/solidity.git
cd solidity
We have a helper script which installs all required external dependencies on macOS, Windows and on numerous Linux distros.
./scripts/install_deps.sh
Or, on Windows (not official verified yet):
scripts\install_deps.bat
Or, on Centos (not official verified yet):
# install z3
https://github.com/Z3Prover/z3
# install deps
scripts\install_deps.bat
Solidity project uses CMake to configure the build. You might want to install ccache to speed up repeated builds. CMake will pick it up automatically. Building Solidity is quite similar on Linux, macOS and other Unices:
mkdir build
cd build
cmake .. && make
See the Solidity documentation for build instructions.
cd solidity
#Prepare to Build solcjson, assume your project dir is "/root/project/solidity"
A "Hello World" program in Solidity is of even less use than in other languages, but still:
# External Dependencies
on Ubuntu
docker run -it -v $(pwd):/root/project -w /root/project trzeci/emscripten:sdk-tag-1.35.4-64bit
apt-get update
apt-get install wget gcc libboost-all-dev
# install essetial
apt-get install -y build-essential
# if "install build-essential" failed, please install Emscripten from this url:
https://github.com/juj/emsdk/tree/llvm_root
# check if boost is installed
./scripts/travis-emscripten/install_deps.sh
# begin to compile
./scripts/travis-emscripten/build_emscripten.sh
# release soljson.js
bash tran.sh
https://solidity.readthedocs.io/en/latest/installing-solidity.html#building-from-source
# install vs2017
# install cmake
scripts\install_deps.bat
部分文件在中文windows下警告被看作错误，改一下文件编码，删除不用的测试就行了
mkdir build
cd build
cmake -G "Visual Studio 15 2017 Win64" ..
cmake --build . --config RelWithDebInfo
pragma solidity ^0.5.0;
contract HelloWorld {
function helloWorld() external pure returns (string memory) {
return "Hello, World!";
}
}
To get started with Solidity, you can use Remix, which is an browser-based IDE. Here are some example contracts:
