在Ubuntu中使用clang ++编译libc ++ [英] compiling libc++ with clang++ in Ubuntu

问题描述

我的操作系统是Ubuntu-11.04
我按照用户手册成功编译了llvm和clang。
然后我试图用clang ++编译libcxx，
i通过读取以下

来修改$ LIBCXX_DIR / lib / buildit.sh

http://lists.cs.uiuc.edu/pipermail/cfe -dev / 2011-February / 013228.html

修改的文件$ LIBCXX_DIR / lib / buildit在错误消息后粘贴。

修改buildit.sh得到以下错误。看来clang ++不能
编译头文件'string'成功。
这是完整的编译报告：

解决方案

好了，错误消息解释了自己，看Howard Hinnant对我的问题的回答： std :: async在clang 3.0 + libc ++不工作？
我猜这是相同的地方。 / p>

My OS is Ubuntu-11.04 i compiled llvm with clang as per the user manual successfully. then i tried to compile libcxx with clang++, i made modifications to the $LIBCXX_DIR/lib/buildit.sh by reading the following

http://lists.cs.uiuc.edu/pipermail/cfe-dev/2011-February/013228.html

The modified file $LIBCXX_DIR/lib/buildit is pasted after the error message.

with the modified buildit.sh i get following errors. It seems clang++ is unable to compile the header file 'string' successfully. Here is the complete compilation report:

解决方案

Well, the error message explains itself, see Howard Hinnant's answer to my question: std::async in clang 3.0 + libc++ doesn't work? I guess that's the same place.

这篇关于在Ubuntu中使用clang ++编译libc ++的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
