help needed on include and -I

[Martin Mensch]

Hello,

 

I am trying to add a path to be searched by include. It all works fine if I use -I <pathname> in the command line, when calling make. But I want to have this inside the makefile. I read in the make manual and in the arcive of help-make that I can change the options or flags inside make:

from make manual:

You can also set MAKEFLAGS in a makefile, to specify additional flags that should also be in effect for that makefile.

 

Now I tried a lot but I just won't work.

Can someone please give me a makefile line that does it. Where do I have to place it? Can it be right befoe the include line?

Can I give only the name of a subdirectory like in -I on the command line and without any ./ or / before and after?

 

Thank you very much.

 

Martin
