在静态Git中链接未定义的参考

Question

我试图通过在我自己的机器（运行Arch Linux）上使用相同的处理器体系结构（x86_64）静态构建git在共享服务器上（没有root访问权限或编译器） ）作为服务器，如this guide中所述。

当我跑make，我总是有这些错误和失败：

Answer 1

我终于发现了a different guide，它建议运行一个稍微不同的.configure命令。什么结束了，我的工作是this guide，在步骤运行

$ ./configure --prefix=/home/myuser/git-static CFLAGS="${CFLAGS} -static" NO_OPENSSL=1 NO_CURL=1

2.

Answer 2

该错误消息表示无法找到的

dlclose 
dlerror 
dleopen 

你需要确保你的定义链接应用程序时，makefile有-ldl。

Answer 3

LDFLAGS是链接器标志。 LIBS用于链接库。混淆它们通常不是问题，但对于静态库，或者当链接器启用了选项时，在使用它的库之前，库函数顺序和任何-l都会被忽略。
