go 編譯二進制運行文件問題記錄

系統包含 sqlite 包的用普通編譯會出現異常

CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o $file_path . #編譯liunx系統可運行文件，會報錯

 

報如下錯誤

github.com/mattn/go-sqlite3

../../mattn/go-sqlite3/sqlite3_opt_preupdate.go:12:16: undefined: SQLiteConn

 

這時應該

CGO_ENABLED=0 改爲 CGO_ENABLED=1

 

下一步運行，若是報

# os/user

該問題 Mac未安裝linux的交叉編譯器。解決方法，安裝linux的交叉編譯器

下載地址

Compiling for Linux 32 and Linux 64 on MacOS X

修改編譯命令爲

CGO_ENABLED=0 GOOS=linux CC=/usr/local/gcc-4.8.1-for-linux64/bin/x86_64-pc-linux-gcc go build -a -installsuffix cgo -o $file_path .

#cc路徑請下載時看清楚安裝包的默認路徑填寫

 

通常編譯出來的文件已經能夠在liunx上運行了，可是若是放在docker上的 alpine系統上又會出現問題會沒法執行問題

這個問題通常是alpine沒有對應的依賴庫能夠用下面的方法解決

 

查看下執行文件的依賴庫：

ldd $WORKDIR/main

/lib64/ld-linux-x86-64.so.2 (0x7fdd15cd0000)

libpthread.so.0 => /lib64/ld-linux-x86-64.so.2 (0x7fdd15cd0000)

libc.so.6 => /lib64/ld-linux-x86-64.so.2 (0x7fdd15cd0000)

直接系統操做

mkdir /lib64

ln -s /lib/libc.musl-x86_64.so.1 /lib64/ld-linux-x86-64.so.2

對應dockerfile裏的操做

RUN mkdir /lib64 && ln -s /lib/libc.musl-x86_64.so.1 /lib64/ld-linux-x86-64.so.2

 

而後就能夠正常工做了，原理是musl和glibc是兼容的，經過建立該符號連接修復缺乏的依賴項。alpine這個5M的鏡像也能知足go二進制文件的運行環境！

對於用alpine做爲go的編譯環境一樣存在上述問題，一樣用相同方法能夠解決。
