避免 cmake 在 MacOS 中添加标志 -search_paths_first 和 -headerpad_max_install_names [英] Avoid cmake to add the flags -search_paths_first and -headerpad_max_install_names in MacOS

问题描述

我正在使用 cmake 在 MacOS 中为 ARM 构建一个 *.elf 文件.CMake 正在自动添加标志 -Wl,-search_paths_first -Wl,-headerpad_max_install_name，这会导致生成无效的 *.elf 文件.我收到错误 warning: cannot find entry symbol arch_paths_first;默认为 00000000080001e0.

I'm building an *.elf file for ARM within MacOS using cmake. CMake is adding the flags -Wl,-search_paths_first -Wl,-headerpad_max_install_name automatically, which leads to produce an invalid *.elf file. I obtain the error warning: cannot find entry symbol arch_paths_first; defaulting to 00000000080001e0.

我尝试在没有这些选项的情况下执行 arm gcc 命令，并且它运行良好.

I have tried to execute the arm gcc command without that options and it works perfectly.

如何停止 cmake 添加这些标志?

How can I stop cmake to add these flags?

推荐答案

我找到了一种方法.

有必要添加以下指令:

set(HAVE_FLAG_SEARCH_PATHS_FIRST 0)

我很确定它必须添加在 project 指令之前.

I'm pretty sure that it must be added before the project directive.

为了删除标志 -headerpad_max_install_names，我在 project 指令之后写了以下内容:

For removing the flag -headerpad_max_install_names, I have written the following after the project directive:

set(CMAKE_C_LINK_FLAGS "")

我想如果我使用 g++ 我应该需要添加

I guess that if I were using g++ I should needed to add

set(CMAKE_CXX_LINK_FLAGS "")
