OK, I see

I did, and now get the library installed, but, again, I get:

g++ -static regex_use.o  -I$HOME/boost/include -L$HOME/boost/lib 
-lboost_regex  -o regex_use_static
/home/bettini/boost/lib/libboost_regex.a(static_mutex.o): In function 
`boost::scoped_static_mutex_lock::unlock()':
static_mutex.cpp:(.text+0x16): undefined reference to `pthread_mutex_unlock'
/home/bettini/boost/lib/libboost_regex.a(static_mutex.o): In function 
`boost::scoped_static_mutex_lock::lock()':
...
/usr/lib/gcc/i486-linux-gnu/4.3.3/libstdc++.a(locale.o): In function 
`std::locale::_Impl::_M_install_cache(std::locale::facet const*, 
unsigned int)':
(.text._ZNSt6locale5_Impl16_M_install_cacheEPKNS_5facetEj+0x2a): 
undefined reference to `pthread_mutex_lock'

If I do (thus, using the .a file directly)

g++ regex_use.o $HOME/boost/lib/libboost_regex.a  -o regex_use_static

I don't get errors, but the binary still uses dynamic libraries:

ldd regex_use_static
        linux-gate.so.1 =>  (0xb800e000)
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7eff000)
        libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7ed9000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb7ec9000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7d66000)
        /lib/ld-linux.so.2 (0xb800f000)

If I add the -static flag to g++ I get the same above errors...
what am I doing wrong?

thanks in advance
        Lorenzo
