无法在Qt5应用程序中加载qca-ossl [英] Cannot load qca-ossl in Qt5 application

问题描述

我决定将我的应用程式从Qt4迁移到Qt5。使用Qt4我使用QCA与QCA-OSSL没有任何问题，但现在OSSL插件不想加载。

I have decided to migrate my application from Qt4 to Qt5. With Qt4 I used QCA with QCA-OSSL without any problem, but now OSSL plugin doesnt want to load.

我从git：//anongit.kde编译QCA。 org / qca.git在Qt5与所有插件没有任何问题。比我添加QCA到我的应用程序（我使用CMAKE），它编译正确，但在运行期间将不允许AES密码，因为OSSL插件没有加载。

I have compiled QCA from git://anongit.kde.org/qca.git under Qt5 with all plugins without any problem. Than I added QCA to my application (I am using CMAKE), it compiled properly, but during run it won't allow AES cipher, because OSSL plugin was not loaded.

我通过论坛搜索，将libqca-ossl.so放入crypto目录，并将此目录复制到我的/ usr / lib / qt / plugins也到我的项目和构建目录，但它没有帮助。

I've searched through forums, put libqca-ossl.so into crypto directory, and copied this dir to my /usr/lib/qt/plugins also to my project and build directory but it did not help.

我会为任何帮助或建议。

I will be thanful for any help or suggestion.

推荐答案

整个问题是在这个...

1）CMake的git：//anongit.kde.org/qca.git生成config-qca.h到QCA源目录。

2）在此文件中有#define QCA_PLUGIN_SUBDIRqca-qt5而不是预测的crypto

Ok I get it working the whole problem was in this...
1) CMake of git://anongit.kde.org/qca.git generates config-qca.h to a QCA source directory.
2) In this file there was #define QCA_PLUGIN_SUBDIR "qca-qt5" instead of predicted "crypto"

一个可能的解决方案是： br />
1）删除QCA中的lib目录（如果有来自先前配置的目录）

2）运行CMAKEARTO
3）更改qca-qt5 到crypto在config-qca.h

4）构建库

One possible solution is:
1) Delete lib dir in QCA (if there is one from previous configuration)
2) Run CMAKE
3) Change "qca-qt5" to "crypto" in config-qca.h
4) Build the library
5) Add library to your project and then it should load all plugins properly
