Question

我试图在我的Mac上构建并运行dragonegg。使用LLVM 3.5和gcc 4.8，来自自制软件包管理器。

根据自述文件（GCC=/usr/local/bin/gcc-4.8 LLVM_CONFIG=/usr/local/bin/llvm-config-3.5 make）编译dragonegg以此错误结束：

Compiling Cache.cpp
/Users/aelberg/Development/dragonegg-3.5.0.src/src/Cache.cpp:243:15: error: no matching function for call to 'operator new'
  WeakVH *W = new (&(*slot)->V) WeakVH(V);
              ^   ~~~~~~~~~~~~~
note: candidate function not viable: requires 1 argument, but 2 were provided
1 error generated.
make: *** [Cache.o] Error 1

这似乎与libc ++与libstdc ++问题有关，这些问题在mac上编译时遇到了问题。并且dragonegg 将使用GCC=/usr/local/bin/gcc-4.8 LLVM_CONFIG=/usr/local/bin/llvm-config-3.5 LDFLAGS="-L/usr/local/lib/ -L/usr/lib -L/usr/local/lib/llvm-3.5/usr/lib" CXX="/usr/local/bin/clang++-3.5 -stdlib=libc++" CXXFLAGS="-I/usr/local/lib/llvm-3.5/include/c++/v1" make

进行编译

然而，当我尝试使用dragonegg编译任何东西时，我得到了一组不幸的错误：

$ /usr/local/bin/gcc-4.8 -fplugin=/usr/local/lib/dragonegg_483_35.so hello.c

$ /usr/local/bin/gcc-4.8 hello.c

$ ./a.out
Hello World

显然，这似乎不太可能涉及用于创建dragonegg的编译器标志中的任何设置，因为它们都与C ++有关。

有什么建议吗？

我找到的解决方案是通过添加-specs=[path to integrated=as.specs]告诉dragonegg使用llvm的汇编程序而不是系统汇编程序。根据dragonegg的文档，这既不是必要的，也不是必须的，但确实如此。
