fedora编译cryptopp失败

cryptopp模块没有做过改动，和编译相关的改动是增加了对于C++11的支持，在Ubuntu上可以编译通过。稍后我会在Fedora上编译测试一下，其他系统上能不能正常编译？

[1dot75cm]

centos 7 暂未测试，一会测试下。 我看ppa上的编译日志buildlog_ubuntu-precise-amd64.wiznote_2.1.17_BUILDING.txt.gz，gcc 用的是 gcc-4.6_4.6.3-1ubuntu5 会有影响么？

[coderlxn]

cryptopp这个类库在使用gcc4.9编译的时候会出现错误，暂时请使用低版本的gcc进行编译。

[1dot75cm]

临时解决此问题，对于 gcc 大于 4.9.0 的发行版，关闭 cryptopp 指令集优化即可。在网上查询 option mismatch 这种现象好像与编译器行为有关，应该可以通过添加某些编译选项进行改变，以兼容旧 ABI 环境下编写的代码。

环境：fedora 22 x86_64, gcc 5.1.1 补丁：# sed -i '1a#define CRYPTOPP_DISABLE_SSE2' lib/cryptopp/config.h 编译结果：https://copr.fedoraproject.org/coprs/mosquito/myrepo/build/89996/

我在debian上编译也失败了，所以我用的是debian源里面的crypto++。 只要改一下CMakeLists.txt就可以了，见https://github.com/sadhen/WizQTClient/commit/393481f270a283d5d6852e4aec6c7f904f7a6ea2

不知道为知笔记有没有对这些库做过什么修改，我直接用debian源里面的库应该没有问题吧？

不知道为知笔记有没有对这些库做过什么修改 .....

WizLxn 说没做什么修改；动态链接程序肯定小了，功能正常么？

[da-liii]

没有修改的话，应该不会有什么异常吧。

反正我一直用着还蛮正常的。我是基本上能用动态链接就用动态链接。

@sadhen

2.2.2 动态链接 quazip，运行会造成段错误，静链一切安好。

使用最新的crypto++(当前是5.6.3)可以成功编译(Ubuntu, gcc-4.9.2)，既然没有修改，建议把crypto++升级到新版本。

另外既然crypto++也是在Github托管的，能否尝试使用git-submodule来管理

369 也是这个问题。
