Debian 32 位主机 PC，在 /opt 目录中具有预构建的工具链，目标是 ARM。我正在尝试从源代码构建项目（f/w 图像），代码编译期间出现错误。该项目结构复杂，有多个自动生成的makefile，递归地位于子目录中，组成了整个系统。我已经修复了编译过程中发生的一些错误，但每次都会出现新的错误。构建停止在某个目录（pppd）：

显示了未定义的引用，因此某些文件，但我确信代码中没有语法错误，它可能由于依赖项或路径损坏而出现。在这个地方，这条路径对我来说看起来是错误的：-I../include '-DDESTDIR="/usr/local"'

我与成功构建的 make.log 进行了比较，它看起来有所不同：

是什么原因导致后面不包含完整路径-I../包括？
