Can't link with Xerces-c static library with g++

Question

I downloaded and unpacked xerces-c-3.1.1-x86_64-linux-gcc-3.4.tar.gz, So I have

$ ls -1 /users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/lib
libxerces-c-3.1.so
libxerces-c.a
libxerces-c.la
libxerces-c.so
pkgconfig

Then I have my Makefile as

CC := gcc
CXX := g++
CXXFLAGS := -O3
LDFLAGS := -O3

CXXFLAGS += -I/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/include
CXXFLAGS += -DXERCES_STATIC_LIBRARY
LDFLAGS += -L/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/lib
LDFLAGS += -Bstatic
LDFLAGS += -lxerces-c

ReadXML: DOM.o MyDOMErrorHandler.o MyXMLString.o ReadXML.o

clean:
    @rm -rvf *.o ReadXML

The make command works fine.

$ make -B
g++ -O3 -I/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/include -DXERCES_STATIC_LIBRARY   -c -o ReadXML.o ReadXML.cpp
g++ -O3 -I/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/include -DXERCES_STATIC_LIBRARY   -c -o DOM.o DOM.cpp
g++ -O3 -I/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/include -DXERCES_STATIC_LIBRARY   -c -o MyDOMErrorHandler.o MyDOMErrorHandler.cpp
g++ -O3 -I/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/include -DXERCES_STATIC_LIBRARY   -c -o MyXMLString.o MyXMLString.cpp
gcc -O3 -L/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/lib -Bstatic -lxerces-c  ReadXML.o DOM.o MyDOMErrorHandler.o MyXMLString.o   -o ReadXML

But the result executable ReadXML is not as "static" as I hope it to be. It prints

./ReadXML: error while loading shared libraries: libxerces-c-3.1.so: cannot open shared object file: No such file or directory

until I setenv LD_LIBRARY_PATH /users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/lib. Obviously, the xerces-c is linked dynamically.

Why the -Bstatic doesn't help me to create a static linked executable?

Update 2013.05.13

Followed @n.m. 's advise and got error like

 gcc -O3 -L/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/lib -Wl,-Bstatic -lxerces-c  ReadXML.o DOM.o MyDOMErrorHandler.o MyXMLString.o   -o ReadXML
/usr/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status
make: *** [ReadXML] Error 1

And with LDFLAGS += -Wl,-Bstatic -lxerces-c -Wl,-Bdynamic, I got

g++ -O3 -L/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/lib -Wl,-Bstatic -lxerces-c -Wl,-Bdynamic -o ReadXML DOM.o MyDOMErrorHandler.o MyXMLString.o ReadXML.o

Answer 1

Thanks for @n.m. 's help. I got the answer after studying a little from libtool. Let me post the answer here.

Finally my working Makefile looks like

CC := gcc
CXX := g++
LD := g++
CXXFLAGS := -O3
LDFLAGS := -O3

CXXFLAGS += -I/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/include
CXXFLAGS += -DXERCES_STATIC_LIBRARY
LDFLAGS += -L/users/jdyu/labs/xerces/xerces-c-3.1.1/lib

ReadXML: DOM.o MyDOMErrorHandler.o MyXMLString.o ReadXML.o
    $(LD) $(LDFLAGS) -o $@ $^ -Wl,-Bstatic -lxerces-c -Wl,-Bdynamic -lnsl -lpthread -lcurl
test: ReadXML
    ldd $(abspath $<)
    $(abspath $<) /users/jdyu/labs/xerces/xerces-c-3.1.1/samples/data/personal.xml

And then the result comes as

$ make -B ReadXML
g++ -O3 -I/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/include -DXERCES_STATIC_LIBRARY   -c -o DOM.o DOM.cpp
g++ -O3 -I/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/include -DXERCES_STATIC_LIBRARY   -c -o MyDOMErrorHandler.o MyDOMErrorHandler.cpp
g++ -O3 -I/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/include -DXERCES_STATIC_LIBRARY   -c -o MyXMLString.o MyXMLString.cpp
g++ -O3 -I/users/jdyu/labs/xerces/xerces-c-3.1.1-x86_64-linux-gcc-3.4/include -DXERCES_STATIC_LIBRARY   -c -o ReadXML.o ReadXML.cpp
g++ -O3 -L/users/jdyu/labs/xerces/xerces-c-3.1.1/lib -o ReadXML DOM.o MyDOMErrorHandler.o MyXMLString.o ReadXML.o -Wl,-Bstatic -lxerces-c -Wl,-Bdynamic -lnsl -lpthread -lcurl

The xerces-c linked statically.

And libtool can make it even more static. Append the make file with

ReadXML_: DOM.o MyDOMErrorHandler.o MyXMLString.o ReadXML.o
    libtool --tag=CXX --mode=link $(LD) $(LDFLAGS) -o $@ $^ -lxerces-c -lnsl -lpthread -lcurl
test_: ReadXML_
    -ldd $(abspath $<)
    $(abspath $<) /users/jdyu/labs/xerces/xerces-c-3.1.1/samples/data/personal.xml

and got the result

$ make ReadXML_
libtool --tag=CXX --mode=link g++ -O3 -L/users/jdyu/labs/xerces/xerces-c-3.1.1/lib -o ReadXML_ DOM.o MyDOMErrorHandler.o MyXMLString.o ReadXML.o -lxerces-c -lnsl -lpthread -lcurl

and

$ make test_
ldd /users/jdyu/labs/xerces/ReadXML/ReadXML_

There is far more in the libtool to learn for me. I tried hard reading libtool code, only to failed to figure out how it coverts the temporary dynamic .libs/ReadXML_ to the final ReadXML_ which is totally static linked. Anyway, the answer of this question is found.

Thanks again, @n.m.
