编译问题

[jicewarwick]

系统: arch-Linux 64 bit

1. 对于qt5, toscii()不再适用,建议换成toLatin1().
   http://qt-project.org/doc/qt-5.1/qtcore/qstring-obsolete.html#toAscii
   影响文件包括:
   /src/client/client.h
   /src/client/client.cpp
   /src/core/jsonutils.h
   /src/core/engine.cpp
2. 还有一个问题:

求解.

原来是 Qt5 的编译问题啊。你说的那个修改方法，与 Qt4.8 兼容么？

不过就你后面的问题确实挺奇怪的，分明是标准的 lua 编译不过。

可能的原因也是 Qt 5 的原因，因为 QSanguosha.pro 调用 Qt 生成 Makefile，决定了其他部分的编译参数。也许用 Qt 5 生成的 Makefile 对其他部分的编译参数不同。

比较靠谱的应该是先用 Qt 4.8 试试，因为目前整个项目都没有做 Qt 5 的兼容，大家都使用 Qt 4.8。

至于什么时候可能考虑切换到 Qt 5，要问项目其他成员了。

我试了一下, 用toLatin1() 可以在4.8下编译.

@jicewarwick toAscii()本来就是Qt为了兼容以前版本所做的函数。

[YanGuam]

@Fsu0413 qt5已不支持使用toAscii

[Fsu0413]

@YanGuam 我知道……
