关于"The dependency was added by the project system and cannot be removed" Error
阅读一个简单地工程代码,其中一个工程BaseCode是 static lib,另一个工程RunBaseCode使用该lib,但在工程设置的“Linker\Input\AdditionalDependencies” 中并没有添加对该lib的引用,而在“Linker\Command Line”中却发现BaseCode.lib已经添加进来了,这是怎么回事呢?
首先怀疑是Solution中设置的 “Project Dependencies”编译依赖,隐含的添加了lib,因此想把RunBaseCode对BaseCode的依赖去掉试试看。取消依赖时,却发现取消不了,出现"The dependency was added by the project system and cannot be removed" 错误。那这个编译依赖是在哪里添加的呢?
原来是在“Project References”中设置的。
右键\Properties\Common Properties\Framework and References\Add New Reference。
设置Reference后,该工程就自动加上了“Project Dependencies”。
那默认添加对BaseCode.lib的引用,是否是由于设置了“Project Dependencies”呢?不是的,是由于上面所述的设置“Reference”导致的。验证的情况如下:
1. 点击“Remove Reference”去掉工程关联后,默认的“Project Dependencies”也取消掉了。这时,手动添加“Project Dependencies”,发现“Linker\Command Line”中没有自动添加BaseCode.lib。
2. 将上一步骤中的“Project Dependencies”去掉,然后“右键\Properties\Common Properties\Framework and References\Add New Reference”,这时“Linker\Command Line”中自动添加了BaseCode.lib。
