构建 llgo+llvm 失败

Question

我试图从源代码构建 llvm 项目。我对使用（检测）go 前端感兴趣。我遵循了 llgo repo 中的步骤。执行时失败

make install

或者，我关注了 building clang 8, llvm 8 on ubuntu 18.04。我设法构建了 clang+llvm。我试图构建 llgo 但失败得很厉害。我错过了什么？

我正在使用 Ubuntu 18.04.2 LTS。

您似乎缺少用于链接的 RAM。尝试不使用 -j 参数的运行 make，将 CMAKE_BUILD_TYPE 切换为 Release 并使用 gold 或 lld 而不是 BFD ld.
