I'll start by stating I'm feeling like a moron tonight. I'm trying to minimally reproduce a work issue I have under RHEL5.6, gcc 4.1.2, boost 1.44.0, with Boost Serialization.
The environment I'm having this issue with is Ubuntu Server (with dev packages installed), gcc 4.7.2, and a build of boost 1.44.0 (against the system compiler, packages, etc).
My code compiles cleanly, but I'm getting a myriad of undefined symbols related to various boost::archive
types. Running strace on my make, I see it picking up the expected boost_serialization library:
668 43569 stat("/usr/local/boost/1.44.0/lib/libboost_serialization.so", {st_mode=S_IFREG|0755, st_size=700481, ...}) = 0
669 43569 open("/usr/local/boost/1.44.0/lib/libboost_serialization.so", O_RDONLY) = 8
My makefile is:
default: test-app
all: test-app
BOOST := /usr/local/boost/1.44.0
CPPFLAGS := -fPIC -Wall -Wextra -Werror
INCDIRS := -isystem$(BOOST)/include
.LIBDIRS. := $(BOOST)/lib
.LIBS. :=boost_serialization
LIBS := $(foreach lib,$(.LIBS.),-l$(lib))
LIBDIRS := $(foreach dir,$(.LIBDIRS.),-L$(dir))
CPPFLAGS += $(INCDIRS)
base.o : base.cpp base.hpp
g++ $(CPPFLAGS) --compile $< -o $@ -g
derived.o : derived.cpp base.hpp derived.hpp
g++ $(CPPFLAGS) --compile $< -o $@ -g
main.o: main.cpp derived.hpp
g++ $(CPPFLAGS) --compile $< -o $@ -g
test-app: main.o derived.o base.o
g++ -o $@ $(LIBDIRS) $(LIBS) $^
clean:
rm -f *.o test
A (very) small sample of the linker errors I'm getting are like:

Likewise, if I do a symbol dump on the referenced .so's, I see the required symbols:
objdump -t /usr/local/boost/1.44.0/lib/libboost_serialization.so |
c++filt | grep

I've been banging my head against the table for a while now…hoping someone can help. I don't think the specific source matters, but if requested, I can post it.

I've had the same problem, putting -lboost_serialization at the end like
should solve it
