Unresolved Symbols linking w/ Boost Serialization under Ubuntu 12.10

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:

base.o: In function void boost::archive::basic_text_oprimitive<std::ostream>::save<boost::archive::class_id_reference_type>(boost::archive::class_id_reference_type const&)': /usr/local/boost/1.44.0/include/boost/archive/basic_text_oprimitive.hpp:91: undefined reference to boost::archive::archive_exception::archive_exception(boost::archive::archive_exception::exception_code, char const*, char const*)' /usr/local/boost/1.44.0/include/boost/archive/basic_text_oprimitive.hpp:91: undefined reference to boost::archive::archive_exception::~archive_exception()' /usr/local/boost/1.44.0/include/boost/archive/basic_text_oprimitive.hpp:91: undefined reference to boost::archive::archive_exception::~archive_exception()' base.o: In function void boost::archive::basic_text_oprimitive<std::ostream>::save<boost::archive::tracking_type>(boost::archive::tracking_type const&)': /usr/local/boost/1.44.0/include/boost/archive/basic_text_oprimitive.hpp:91: undefined reference to boost::archive::archive_exception::archive_exception(boost::archive::archive_exception::exception_code, char const*, char const*)' /usr/local/boost/1.44.0/include/boost/archive/basic_text_oprimitive.hpp:91: undefined reference to boost::archive::archive_exception::~archive_exception()' /usr/local/boost/1.44.0/include/boost/archive/basic_text_oprimitive.hpp:91: undefined reference to boost::archive::archive_exception::~archive_exception()' base.o: In function void boost::archive::basic_text_oprimitive<std::ostream>::save<unsigned int>(unsigned int const&)': /usr/local/boost/1.44.0/include/boost/archive/basic_text_oprimitive.hpp:91: undefined reference to boost::archive::archive_exception::archive_exception(boost::archive::archive_exception::exception_code, char const*, char const*)' /usr/local/boost/1.44.0/include/boost/archive/basic_text_oprimitive.hpp:91: undefined reference to boost::archive::archive_exception::~archive_exception()' /usr/local/boost/1.44.0/include/boost/archive/basic_text_oprimitive.hpp:91: undefined reference to boost::archive::archive_exception::~archive_exception()'

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 "boost::archive::archive_exception::~archive_exception()" 000000000004e670 g F .text 0000000000000065

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

g++ -L/usr/local/boost/1.44.0/lib -o test-app main.o derived.o base.o -lboost_serialization

should solve it

the binary object .o is not linked with libs.
first verify that in /usr/local/boost/1.44.0/lib there are file's lib boost_serialization.
and next, that lib is registered:
sudo ldconfig -v | grep boost_serialization
if not, create file boost1.44.0.conf in /etc/ld.so.conf.d with user root. With this ligne
usr/local/boost/1.44.0/lib
then start this command
sudo ldconfig -v | grep boost_serialization
