我正在使用此源,但出现此错误:
In file included from /usr/include/boost/filesystem.hpp:15:0,
[LIST=1]
from luascript.cpp:21:
/usr/include/boost/filesystem/config.hpp:16:5: error: #error Compiling Filesystem version 3 file with BOOST_FILESYSTEM_VERSION defined != 3
luascript.cpp: In member function ‘bool LuaInterface::loadDirectory(const string&, Npc*, bool)’:
luascript.cpp:745:61: error: no match for ‘operator+’ in ‘boost::filesystem::path::filename() const() + "/"’
make[1]: *** [luascript.o] Error 1
make[1]: *** Waiting for unfinished jobs....
make[1]: Leaving directory `/home/dv/src.DEB'
make: *** [all] Error 2
[/LIST]
加上这段代码:
if(boost::filesystem::is_directory(it->status()))
{
if(recursively && !loadDirectory(it->path().filename() + "/" + s, npc, recursively))
return false;
}
最佳答案
你想要
if(recursively && !loadDirectory(it->path() / s, npc, recursively))
return false;
它更短、更优雅,针对分配进行了优化并且平台无关!
IMO 这是非传统运算符重载在 C++ 中实现“即时”直观 eDSL 的非传统运算符重载非常好的罕见情况:)
关于c++ - 错误 : no match for ‘operator+’ in ‘boost::filesystem::path::filename() const() + "/"’ ,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/20937308/
