Hi Honza,

first, thanks for your appreciation Smile

.

A problem I have is to find a way to define variables when calling make which can be extended then during the make flow.
I thought VAR+=x should work, but it does not work for env variables defined as parameter to make, like this:

make DEFS=-DflagNOGTK

In this case the variable DEFS is completely overwritten by -DflagNOGTK. But what I want is to add this flag to already defined flags inside the Makefile.

Do you have an idea?

Matthias

Hi,

This is usually solved using another variable:

FIXEDFLAGS=...
FLAGS=$(FIXEDFLAGS) $(DEFS)

.

Simple, stupid, but works Smile
