Re: 回复： 回复： 回复： 回复： 回复： Ninja compilation fail s after using include path file instead of "-I" opti on

Can you give me more information? What source file? Does the compilation
fail the first time? Does it recompile successfully with only scons
building? Can you push your latest code so I can see it in your repo?

 Also each builder can only hold one target or source scanner, but you can
chain the scanner by calling other scanners from within the single scanner.
Are you assigning multiple scanners to the same builder?
