MinGW / libssl链接错误

标签： c linker mingw linker-errors

我正在将我在Linux中开发的应用程序移植到Windows，并且在构建应用程序时遇到了一些问题。在进行必要的代码更改后，所有内容都编译得很好（当在Visual Studio中构建为调试版本时，运行没有任何问题）。我需要在MinGW中构建它，当我尝试将它与liboauth链接时我遇到了链接器错误，这也是我的项目所必需的。

命令及其输出如下：

gcc application.o service.o util.o json.o api.o -L/usr/local/lib -lcrypto -lssl -lcurl -ljansson -loauth -Wl -o application

我在lib路径中拥有所有必需的库，并且由于某种原因，liboauth无法找到对libssl和libcrypto的引用。这一切都在Linux中构建良好。有什么想法吗？

更新

根据回复，我更新了我的链接器命令，以便以不同的顺序链接库。我的新命令如下：

gcc -o application application.o service.o util.o json.o api.o -Lc:/mingw/msys/1.0/local/lib -loauth -ljansson -lcurl -lssl -lcrypto

这解决了上一个问题并提出了一组新的链接器错误：

gcc -o application application.o service.o util.o json.o api.o -Lc:/mingw/msys/1.0/local/lib -loauth -ljansson -lcurl -lssl -lcrypto

快速谷歌搜索返回我还应该链接到gdi32库（用于与我的任务无关的目的。链接器的最终命令如下：

gcc -o application application.o service.o util.o json.o api.o -Lc:/mingw/msys/1.0/local/lib -loauth -ljansson -lcurl -lssl -lcrypto -lgdi32

答案 0 :(得分：2)

试试这个：

gcc -o application application.o service.o util.o json.o api.o -Lc:/mingw/msys/1.0/local/lib -loauth -ljansson -lcurl -lssl -lcrypto
