C++ Qt QT5网络链接错误的静态构建
我正在尝试使用OpenSSL支持对Qt（版本5.4.1）进行静态构建。我将其配置如下：C++ Qt QT5网络链接错误的静态构建,c++,qt,deployment,compilation,static-linking,C++,Qt,Deployment,Compilation,Static Linking,我正在尝试使用OpenSSL支持对Qt（版本5.4.1）进行静态构建。我将其配置如下： configure -opensource -release -c++11 -static -platform win32-msvc2013 -openssl-linked -I C:\OpenSSL-Win32\include -L C:\OpenSSL-Win32\lib\VC\static -nomake examples -nomake tests include和lib目录是有效的。我在Qt

在我编译的OpenSSL构建中，或者在二进制发行版中，我都找不到ssl或加密库。不过我有标题。我只有ssleay32和libeay32库 configure命令不提示将这些库设置为上述变量：
NOTE: When linking against OpenSSL, you can override the default
library names through OPENSSL_LIBS
and optionally OPENSSL_LIBS_DEBUG/OPENSSL_LIBS_RELEASE
For example:
configure -openssl-linked OPENSSL_LIBS="-lssleay32 -llibeay32"
我仍然在寻找一个静态链接OpenSSL的解决方案。我仍然有相同的链接错误。不久前，我以某种方式使Qt 5.3运行得相当快：
configure -static -debug-and-release -platform win32-msvc2012-mt -openssl -I %OPENSSL_HOME%\include -L %OPENSSL_HOME% -nomake examples -nomake tests -confirm-license -opengl es2 -skip qtwebkit -skip qtwebkit-examples -skip qttools
LIBS += -L$$PWD/../third-party/openssl/lib -llibeay32MT
LIBS += -L$$PWD/../third-party/openssl/lib -lssleay32MT
OPENSSL_HOME变量设置为ProjectDir\third-party\OPENSSL我刚刚花了大约一天的时间处理这个静态构建，对我来说有效的是： 另外，您必须注意，我使用了

我遇到了同样的问题，我认为问题在于我们首先在没有ssl的情况下进行构建，并且不会重新生成src/network/makefile 当我删除它们并再次运行configure时，我成功了
希望这有帮助这是一个老问题，但我会给出答复 这取决于开放式ssl的版本。如果您使用的是低于1.1.0的版本，上述顺序可能还可以，但是根据我的经验，使用1.1.1不需要OPENSSL_LIBS=“-LC:\OPENSSL-Win32\lib-lssl-lcrypto”。配置时，会有一个名为QtNetowrk的项，它显示是否已检测到openssl库。以下内容适用于1.1.1静态和qt 5.12.4

很可能是一个Qt错误，那么在Qt-JIRA中报告它是值得的。当你说“Qt5.4”时，你是指5.4.0还是5.4.1？@FrankOsterfeld谢谢你，我已经把它报告为一个bug。我的意思是5.4.1，很抱歉不准确。@Frankosterfield我得到的答案是，这不是一个bug，但就我个人而言，我还没有完全判定它是错误。你能推荐一个Qt版本来试用吗？“在我编译的OpenSSL版本中找不到ssl或加密库”好吧，先解决这个问题，你的问题与Qt无关。@KubaOber说起来容易做起来难。我已经下载了OpenSSL for Windows的官方二进制发行版，但它不包含它。我不知道我能做些什么。
