平台:macOS 11.1

当我尝试配置 Trilinos 时,我遇到了一个问题,我无法处理它。以下命令用于编译 Trilinos:

#!/bin/bash
rm -rf CMakeCache.txt
rm -rf CMakeFiles
rm -rf CMakeCache.txt

错误信息如下所示:

  It fails with the following output:

  CMake will not be able to correctly generate this project.

我真的不知道如何解决它。我还尝试将 gcc 编译器设置为自制 gcc 而不是 clang。

谁能帮我解决这个问题?

Xcode 工具链不支持 OpenMP。除了他们希望您使用 Apple 特定的 API(显然不等效)之外,没有其他技术原因。

要使用 OpenMP,您可以使用应该能够通过 Homebrew 安装的LLVM Clang/libc++/libopenmp :

brew install --with-toolchain llvm

或自己从源代码构建。
