Question

我正在尝试在Linux下为win32交叉编译一个小程序。它使用libarchive，可以在我的fedora 23安装上使用mingw（全部通过dnf安装），但是我收到很多链接器错误。

来源：https://github.com/panzi/save_the_zazus

编译器/链接器输出：

对于这个单一源文件程序，我刚写了一个简单的Makefile。 png文件不在repo中（尚未），因此如果您尝试编译，只需为它们创建空文件。我尝试了动态和静态链接（更喜欢静态，所以我需要做的就是传递一个.exe文件）。对于此输出，我使用-static -larchive并且它不会抱怨任何缺少的库，但我得到所有这些未定义的引用。

Answer 1

将-static -larchive添加到命令行的末尾，然后重试。链接器没有得到链接的库。我发现它需要在命令行上排在最后。

mingw + libarchive：交叉编译链接器错误
