我的操作系統是Ubuntu-11.04 我按照用戶手冊成功編譯了帶有clang的llvm。 然後我試圖編譯libcxx與鐺++， 我通過閱讀下面的在Ubuntu中使用clang ++編譯libC++
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2011-February/013228.html
的修改的文件$ LIBCXX_DIR/LIB/buildit之後粘貼所做的修改到$ LIBCXX_DIR/LIB/buildit.sh錯誤信息。
與修改後的buildit.sh我得到以下錯誤。看來鏗鏘聲++不能 成功地編譯頭文件'string'。 下面是完整的報告彙編：
