blockchain - 安装solc install solc, not solcjs
solcjs : node package
solc solcjs 两者不一样，参数不兼容。所以，有时候我们需要使用solc 来执行一些命令
安装方法：在上面的 https://github.com/ethereum/solidity/releases 中，直接下载二进制文件即可。
cp ~/Downloads/solc-static-linux /workspace/coding_tools/
把solc复制到workspace需要用到的工具文件夹
复制到usr/bin文件夹
linlin@linlin-i5:/workspace$ sudo cp ~/Downloads/solc-static-linux /usr/bin/
[sudo] password for linlin:solcjs的使用

solc, the Solidity commandline compiler.
This program comes with ABSOLUTELY NO WARRANTY. This is free software, and you
are welcome to redistribute it under certain conditions. See 'solc --license'
for details.
Usage: solc [options] [input_file...]
Compiles the given Solidity input files (or the standard input if none given or
"-" is used as a file name) and outputs the components specified in the options
at standard output or in files in the output directory, if specified.
Imports are automatically read from the filesystem, but it is also possible to
remap paths using the context:prefix=path syntax.
Example:
solc --bin -o /tmp/solcoutput dapp-bin=/usr/local/lib/dapp-bin contract.sol
General Information:
--help Show help message and exit.
--version Show version and exit.
--license Show licensing information and exit.
--input-file arg input file
Input Options:
--base-path path Use the given path as the root of the source tree
instead of the root of the filesystem.
--include-path path Make an additional source directory available to the
default import callback. Use this option if you want to
import contracts whose location is not fixed in relation
to your main source tree, e.g. third-party libraries
installed using a package manager. Can be used multiple
times. Can only be used if base path has a non-empty
value.
--allow-paths path(s)
Allow a given path for imports. A list of paths can be
supplied by separating them with a comma.
--ignore-missing Ignore missing files.
--error-recovery Enables additional parser error recovery.
Output Options:
-o [ --output-dir ] path
If given, creates one file per component and
contract/file at the specified directory.
--overwrite Overwrite existing files (used together with -o).
--evm-version version (=london)
Select desired EVM version. Either homestead,
tangerineWhistle, spuriousDragon, byzantium,
constantinople, petersburg, istanbul, berlin or london.
--experimental-via-ir
Deprecated synonym of --via-ir.
--via-ir Turn on compilation mode via the IR.
--revert-strings debug,default,strip,verboseDebug
Strip revert (and require) reason strings or add
additional debugging information.
--debug-info arg (=ast-id,location,snippet)
Debug info components to be included in the produced EVM
assembly and Yul code. Value can be all, none or a
comma-separated list containing one or more of the
following components: ast-id, location, snippet.
--stop-after stage Stop execution after the given compiler stage. Valid
options: "parsing".
Alternative Input Modes:
--standard-json Switch to Standard JSON input / output mode, ignoring
all options. It reads from standard input, if no input
file was given, otherwise it reads from the provided
input file. The result will be written to standard
output.
--link Switch to linker mode, ignoring all options apart from
--libraries and modify binaries in place.
--assemble Switch to assembly mode, ignoring all options except
--machine, --yul-dialect, --optimize and
--yul-optimizations and assumes input is assembly.
--yul Switch to Yul mode, ignoring all options except
--machine, --yul-dialect, --optimize and
--yul-optimizations and assumes input is Yul.
--strict-assembly Switch to strict assembly mode, ignoring all options
except --machine, --yul-dialect, --optimize and
--yul-optimizations and assumes input is strict
assembly.
--import-ast Import ASTs to be compiled, assumes input holds the AST
in compact JSON format. Supported Inputs is the output
of the --standard-json or the one produced by
--combined-json ast
--lsp Switch to language server mode ("LSP"). Allows the
compiler to be used as an analysis backend for your
favourite IDE.
Assembly Mode Options:
--machine evm,ewasm Target machine in assembly or Yul mode.
--yul-dialect evm,ewasm
Input dialect to use in assembly or yul mode.
Linker Mode Options:
--libraries libs Direct string or file containing library addresses.
Syntax: <libraryName>=<address> [, or whitespace] ...
Address is interpreted as a hex string prefixed by 0x.
Output Formatting:
--pretty-json Output JSON in pretty format.
--json-indent N (=2) Indent pretty-printed JSON with N spaces. Enables
'--pretty-json' automatically.
--color Force colored output.
--no-color Explicitly disable colored output, disabling terminal
auto-detection.
--error-codes Output error codes.
Output Components:
--ast-compact-json AST of all source files in a compact JSON format.
--asm EVM assembly of the contracts.
--asm-json EVM assembly of the contracts in JSON format.
--opcodes Opcodes of the contracts.
--bin Binary of the contracts in hex.
--bin-runtime Binary of the runtime part of the contracts in hex.
--abi ABI specification of the contracts.
--ir Intermediate Representation (IR) of all contracts.
--ir-optimized Optimized intermediate Representation (IR) of all
contracts.

--metadata Combined Metadata JSON whose Swarm hash is stored
on-chain.
--storage-layout Slots, offsets and types of the contract's state
variables.
Extra Output:
--gas Print an estimate of the maximal gas usage for each
function.
--combined-json abi,asm,ast,bin,bin-runtime,devdoc,function-debug,function-debug-runtime,generated-sources,generated-sources-runtime,hashes,metadata,opcodes,srcmap,srcmap-runtime,storage-layout,userdoc
Output a single json document containing the specified
information.
Metadata Options:
--metadata-hash ipfs,none,swarm
Choose hash method for the bytecode metadata or disable
it.
--metadata-literal Store referenced sources as literal data in the metadata
output.
Optimizer Options:
--optimize Enable bytecode optimizer.
--optimize-runs n (=200)
The number of runs specifies roughly how often each
opcode of the deployed code will be executed across the
lifetime of the contract. Lower values will optimize
more for initial deployment cost, higher values will
optimize more for high-frequency usage.
--optimize-yul Legacy option, ignored. Use the general --optimize to
enable Yul optimizer.
--no-optimize-yul Disable Yul optimizer in Solidity.
--yul-optimizations steps
Forces yul optimizer to use the specified sequence of
optimization steps instead of the built-in one.
Model Checker Options:
--model-checker-contracts default,<source>:<contract> (=default)

--model-checker-timeout ms
Set model checker timeout per query in milliseconds. The
default is a deterministic resource limit. A timeout of
0 means no resource/time restrictions for any query.
