Question

我尝试在Linux上构建独立服务器，请遵循以下指示： https://github.com/kazuho/h2o 但是当我键入＆＃34; make h2o＆＃34;时，我收到了一个错误：

任何人都可以告诉我具体如何解决？非常感谢！

如评论中所述，最终的可执行文件应与dl库链接。虽然并非所有系统都需要这样，但是h2o的上游作者应该修复它。

如果您正在寻求快速和彻底的修复，请打开CMakeLists.txt文件并替换该行：

TARGET_LINK_LIBRARIES(h2o ${OPENSSL_LIBRARIES} ${LIBYAML_LIBRARIES} pthread)

带

TARGET_LINK_LIBRARIES(h2o ${OPENSSL_LIBRARIES} ${LIBYAML_LIBRARIES} pthread -ldl)

make C代码时libcrypto.a出错
