链接失败与铿锵/ llvm使用g ++

我想编译这个.ccp文件。我从https://github.com/loarabia/Clang-tutorial得到它。链接失败与铿锵/ llvm使用g ++

我想补充的是这样的情况，你的时候添加这个clang::CompilerInstance compInst;代码行。没有这条线，它通常编译。

而且我用铛/ LLVM 3.0，它使用本教程http://clang.llvm.org/get_started.html

任何建议，为什么它可能失败建？

您可能没有按照正确的顺序列出正确的库。我不知道什么是正确的名单是我的头顶，但至少你错过了-lclangSerialization。

这正是丢失的东西！天才！非常感谢！ – scherka 2011-12-24 14:47:42

命令行中库的顺序可能是错误的。尝试使用项目中给出的makefile - https://github.com/loarabia/Clang-tutorial/blob/master/makefile。只需将makefile复制到您的目录并运行make。

标准包含目录中没有clang/llvm源文件，所以makefile不能'为我做这些东西 – scherka 2011-12-24 14:49:10
