building a completely static executable (using boost regex library)

[Lorenzo Bettini]

Hi

I was trying to build, in linux, a completely static executable that 
uses libboost_regex;

I issued

configure LDFLAGS="-static"
make LDFLAGS="-all-static"

but when it comes to linking I get this error:

/bin/bash ../libtool --tag=CXX   --mode=link g++  -g -O2 -L/usr/lib 
-all-static -o check-regexp check-regexp_cmd.o check-regexp.o 
-lboost_regex ../gl/libgnu.la
libtool: link: g++ -g -O2 -static -o check-regexp check-regexp_cmd.o 
check-regexp.o  -L/usr/lib -lboost_regex ../gl/.libs/libgnu.a
/usr/lib/libboost_regex.a(static_mutex.o): In function 
`boost::scoped_static_mutex_lock::unlock()':

what am I doing wrong?

thanks in advance
