铿锵建造错误
我试图在Ubuntu 16.04上构建铿锵中继,无论我尝试什么,我都会生成错误。 首先,我建立了对gcc 5.4的llvm / clang / libc ++ / libc ++ abi,这工作得很好。 现在我正在尝试使用我刚刚构建的clang来重建llvm / clang / libc ++ / libc ++ abi。 这会失败,并显示以下错误消息:

相关的错误是未定义的符号:
In function (anonymous namespace)::DFAPacketizerEmitter::run(llvm::raw_ostream&)': /home/mehrlich/Code/llvm/llvm/utils/TableGen/DFAPacketizerEmitter.cpp:(.text._ZN12_GLOBAL__N_120DFAPacketizerEmitter3runERN4llvm11raw_ostreamE+0x253f): undefined reference to std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>::~basic_string()'
推测这是出于以下两个原因之一:
1. Clang使用libstdc ++头文件:
我们可以从失败的命令中看到,clang ++正确地选择了-stdlib = libc ++开关。 运行% clang++ --stdlib=libc++ -E -x c++ - -v < /dev/null
使用此选项检查默认包含路径

第一个头文件搜索路径#include <...> search starts here: /usr/local/bin/../include/c++/v1
c++ #include <...> search starts here: /usr/local/bin/../include/c++/v1
是libc ++头文件的正确位置。 所以我非常怀疑这是
2. Clang没有链接到libc ++
将选项-lc++ -lc++abi
到CMAKE_EXE_LINKER_FLAGS,CMAKE_SHARED_LINKER_FLAGS,CMAKE_MODULE_LINKER_FLAGS和CMAKE_STATIC_LINKER_FLAGS会出现以下错误:

我们可以看到这一点,链接器选项被cmake传递给/usr/bin/ar
作为静态库(这看起来像对我来说是错误的事情,但我不是构建过程的专家,所以我可能会错误)。 从CMAKE_STATIC_LINKER_FLAGS中删除这些选项会还原为有关未定义符号的原始错误消息,因此推测llvm-tblgen
目标是静态库。 llvm-tblgen
肯定是一个可执行文件,不确定CMAKE_EXE_LINKER_FLAGS没有被应用到它的标志被应用,这意味着我不知道为什么这不会工作...
在这一点上,我不确定这是谁的错,我的,叮当,或cmake,但如果任何人有任何建议或在这个过程中的专业知识,我会很感激帮助。
更新
现在错误在编译器rt中:

似乎与这个错误有关
这是由libc ++最近的一个错误引起的,它意外地从libc++.so
版本中删除了~basic_string()
的定义,这些版本都是用GCC构建的。 这个错误是在9月9日引入的,我今天早些时候修复了它。
不幸的是,你的libc ++安装有问题,它需要在构建Clang之前进行更新。 您可以简单地在现有安装之上安装新的libc ++。 这可以使用sudo make install-cxx
从你当前的(buggy)构建目录中完成。 然后你可以像平常一样继续建立Clang。
有关构建/安装libc ++的更多信息,请参阅http://libcxx.llvm.org/docs/BuildingLibcxx.html。
(注意:修复libc ++安装不应该需要重建LLVM或Clang。)
