Re: [Boost-users] Serialize a vector of lists with boost

I have boost installed from repository, so they are in standard path: 
/usr/ include and /usr/lib.
The only missing thing was the serialization flag which to me is not 
-lserialization, but -lboost_serialization-mt.
I wrote a little make file to compile the example:

NAME=p1
CXX=g++
FLAGS=-Wall -pedantic -g -O3 -DDEBUG -march=native -std=c++0x

BINDIR=.

all: $(NAME)

clean:
     rm -f $(NAME)
     rm -f ar.txt ar.xml

install: $(NAME)
     cp $(NAME) $(BINDIR)

uninstall:
     rm -f $(BINDIR)/$(NAME)

$(NAME): p1.cxx
     $(CXX) $(FLAGS) -lboost_serialization-mt -o $(NAME) p1.cxx

Now it compiles and run perfectly: I can start learning stuff! :-D

Merci beaucoup ;-)
