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*.elf文件. CMake将自动添加标志-Wl,-search_paths_first -Wl,-headerpad_max_install_name，这将导致生成无效的*.elf文件.我收到错误warning: cannot find entry symbol arch_paths_first; defaulting to 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.

我试图在不使用该选项的情况下执行arm gcc命令，并且效果很好.

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)

我很确定必须在project指令之前添加它.

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 "")

我想如果我正在使用g++，我应该添加

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

set(CMAKE_CXX_LINK_FLAGS "")
