Re: Exported vs command line variables

[Rakesh Sharma]

There is no difference between the two. They both declare environment variables 
for make.

Subject: Exported vs command line variables

Hi,

I have noticed that there is a difference between the two scenarios
listed below:

i) make  CC=arm-linux-gnueabihf-gcc CPPFLAGS=[..]

ii) export CPPFLAGS=[..] [RET]
    make CC=arm-linux-gnueabihf-gcc


I have read over internet that the latter is used when appending
instead of replacing/setting the variable's value.

What is exactly the difference ? Is there a page in the Make manual
explaining that ?


Thanks a lot,
P.
