gcc 升级后，我的项目由于错误而无法构建：

可能是什么？我也尝试过最新的 gcc (4.8) 快照，但没有帮助。

附言

extra/boost 1.49.0-1 [installed]
core/gcc 4.6.3-1 (base-devel) [installed]
aurbuild/luabind 0.9.1-1 [installed]

【问题讨论】：

能否请您提供最少的代码来解决至少一种输出错误的情况？
@izomorphius 错误与我的代码无关。我已经删除了 luabind 并下载了最新的稳定版本。由于给定文件中的错误（来自错误输出），我无法构建它。
所有这些你得到错误的行都类似于#elif BOOST_PP_ITERATION_FLAGS() == 1
我已经更改了您问题的摘要，以便在搜索错误时更容易找到它。

【解决方案1】：

由于 luabind 以谷歌 google project 的形式存在，我能够浏览代码并找到导致错误的行。它们看起来都像：

#elif BOOST_PP_ITERATION_FLAGS() == 1

似乎其他人遇到了这个问题，我找到了这个thread，希望对您有所帮助。

【讨论】：

谢谢。也许，你知道如何解决它：#define BOOST_PP_ITERATION_PARAMS_1 (4, (0, LUABIND_MAX_ARITY, <luabind/wrapper_base.hpp>, 1)) 我从未使用过 BOOST 的这个宏。
据我所知，这家伙只是将 elif 更改为 else if，这似乎可以解决问题。它不适合你吗？
在wrapper_base.hpp中，在第93行左右添加#else和#if后，需要在文件末尾额外添加#endif。
