Question

当我尝试编译脚本时，我收到错误：

/usr/lib/gcc/i686-pc-cygwin/6.4.0/../../../../i686-pc-cygwin/bin/ld: cannot find -lecc

collect2：错误：ld返回1退出状态 make：*** [Makefile：9：sample]错误1

Answer 1

您告诉编译器链接“libecc.a”。您在编译器的“lib”文件夹中没有此库，或者您的编译器所在的路径中没有该库。尝试将-L添加到链接步骤或检查您的lib文件夹并确保您拥有该库。

<强> UPD
另请注意error: ld returned 1 exit status错误来自链接器。您可以检查所需的库ecc是否已安装like this：

ldconfig -p | grep libecc

我正在尝试使用cygwin gcc编译我的c程序，但是当我尝试这样做时出现错误
