Filecoin开发代码开源后，赛道中国第一时间进行了编译，第三天赛道云成功稳定运行开发测试节点，IPFSSDKJ节点。
安装Filecoin及相关程序
参考官方安装文档，目前只能从源代码安装，而且只支持Linux和MacOS，Windows再次被歧视（我手头这个旧Macbook Pro是能试试的）。
官方文档是先把源码下载了再说，用下面的命令。
mkdir -p ${GOPATH}/src/github.com/filecoin-project
git clone https://github.com/filecoin-project/go-filecoin.git ${GOPATH}/src/github.com/filecoin-project/go-filecoin
但实际上，这条命令依赖于 ${GOPATH}这个环境变量，以及Go语言环境的目录。所以，最好还是先检查相关的程序与环境是否已经OK。
安装Go 和 Rust
编译go-filecoin需要的环境如下
Go= v1.11.2.
用go version检查一下版本
$go version
go version go1.10.2 darwin/amd64
我之前的Go是用Home Brew安装的，直接用brew upgrade go更新就好了
$brew upgrade go
==> Upgrading 1 outdated package:
go 1.10.2 -> 1.11.5

==> Pouring go-1.11.5.mojave.bottle.tar.gz
/usr/local/Cellar/go/1.11.5: 9,298 files, 404.3MB
$go version
go version go1.11.5 darwin/amd64
Rust >= v1.31.0 and cargo
继续用Home Brew好了 brew install rust
$ brew install rust
Updating Homebrew...
==> Installing dependencies for rust: openssl, libssh2 and pkg-config
==> Installing rust dependency: openssl

######################################################################## 100.0%
==> Pouring openssl-1.0.2q.mojave.bottle.tar.gz
==> Caveats
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
/usr/local/etc/openssl/certs
and run
/usr/local/opt/openssl/bin/c_rehash
openssl is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.
If you need to have openssl first in your PATH run:
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
For compilers to find openssl you may need to set:
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig"
检查一下版本 rustc --version，cargo --version
$ rustc --version
rustc 1.32.0
$ cargo --version
cargo 1.32.0
pkg-config go-filecoin 用这个来生成link flag
Mac OS 上可以用brew来安装 brew install pkg-config
另外，Filecoin说还用了cgo，因此需要C编译器，以前应该在Mac上安装过开发者工具包，用CC --version 检查一下
$ CC --version
Apple LLVM version 10.0.0 (clang-1000.10.44.4)
Target: x86_64-apple-darwin18.2.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
修改环境变量
修改${GOPATH} 和 ${PATH}环境变量，和我电脑上Go的安装目录保持一致。在~/.bash_profile 中增加 export GOPATH="/Users/Hooman/go" export PATH="$PATH:$GOPATH/bin"
$ go env GOPATH
/Users/Hooman/go
$ . ~/.bash_profile
$ echo ${GOPATH}
/Users/Hooman/go
下载Filecoin源码
mkdir -p ${GOPATH}/src/github.com/filecoin-project
git clone https://github.com/filecoin-project/go-filecoin.git ${GOPATH}/src/github.com/filecoin-project/go-filecoin
安装Go-filecoin依赖的软件包
go-filecoin 依赖一些Rust写的子模块代码，需要确保cargo已经安装好了。
这些依赖的软件包用gx管理，运行下面这两条命令安装gx, gometalinter等等编译、测试相关的一堆东西：
cd ${GOPATH}/src/github.com/filecoin-project/go-filecoin
FILECOIN_USE_PRECOMPILED_RUST_PROOFS=true go run ./build/*.go deps
这会花点时间，如果发现这个错误
gx install
panic: exec: "gx": executable file not found in $PATH
那么是因为没有把${GOPATH}/bin 增加到 ${PATH} 里，照着上面把环境变量设置好再来一次。
不知为何，我的电脑上提示没找到Rust的预编译包，结果整个重新编译，用了相当长时间（远远不止一杯咖啡）
using precompiled rust-proofs

趁此机会，我大致浏览了一下Filecoin 的代码介绍/Codewalk，这是一个了解代码结构的绝佳入手点，下面这张图就是摘自这里。

最终如果没错，命令的输出会类似下面这样：
$ cd ${GOPATH}/src/github.com/filecoin-project/go-filecoin
$ FILECOIN_USE_PRECOMPILED_RUST_PROOFS=true go run ./build/*.go deps
pkg-config --version
0.29.2

编译、测试、安装
# First, build the binary
go run ./build/*.go build
# Install go-filecoin to ${GOPATH}/bin (necessary for tests)
go run ./build/*.go install
# Then, run the tests.
go run ./build/*.go test
# Build and test can be combined!
go run ./build/*.go best
上面这些命令，只需执行前三个，或者最后一个三合一版本的命令。注意，第三个命令是执行测试，测试的时间其实也挺长的。另外一些编译时用得上的命令如下，
# Check the code for style and correctness issues
go run ./build/*.go lint
# Test with a coverage report
go run ./build/*.go test -cover
# Test with Go's race-condition instrumentation and warnings (see https://blog.golang.org/race-detector)
go run ./build/*.go test -race
# Deps, Lint, Build, Test (any args will be passed to `test`)
go run ./build/*.go all
