mac开发-install_name_tool: changing install names or rpaths can't be redone for:

类似错误如下:

error: install_name_tool: changing install names or rpaths can't be redone for: /Users/gensee/Library/Developer/Xcode/DerivedData/Training-emkrlchivsbjssanebsiarnsozuw/Build/Products/Debug/Training.app/Contents/MacOS/Training (for architecture x86_64) because larger updated load commands do not fit (the program must be relinked, and you may need to use -headerpad or -headerpad_max_install_names)

原因是我引入了dylib库，需要修改其引用关系，所以使用了 install_name_tool 命令添加了 修改脚本 ，发生了这个报错

解决方法是在other linker中添加

-headerpad_max_install_names

-headerpad_max_install_names

作用就是允许开发人员修改dylib的

install_name

为其想要的值，如果不设置，大概率会出现脚本错误。

同时也可能导致 codesign_allocate: can’t allocate code signature data 的错误
