Re: [A-a-p-user] how do I change compilation flags for selected targets?

[Lars I. I. <lar...@ig...>]

I  think that the OPTIMIZE variable is the one to use.

Does

SOURCES = main.cpp ext.cpp { var_OPTIMIZE = 2 }

work?

Adriaan, thanks for the quick answer.

with a little change (
SOURCES =· main.cpp  ext.cpp { add_CXXFLAGS = -O2 }
) this works, sort of. the Flag is appended - this is what add_* does.

the compilation is done with this commandline:
g++    -O1 -O2 -O2 -c -o build-Linux2_4_20_web/ext.o ext.cpp

this is not clean: it lets the compiler dedice what to do about
the different -Ox's on the commandline.

maybe Bram knows this: is there a way to change the values of a
variable for one (or a set of) targets?

I think, that special filetypes are the overkill for that.
