Hello John,

I find following *.a *.so but no libboost_regex.so
at path :/home/ChandanNilange/work/boost/lib

libboost_regex-gcc34-1_34.a
libboost_regex-gcc34-1_34.so
libboost_regex-gcc34-1_34.so.1.34.0
libboost_regex-gcc34.a
libboost_regex-gcc34-d-1_34.a
libboost_regex-gcc34-d-1_34.so
libboost_regex-gcc34-d-1_34.so.1.34.0
libboost_regex-gcc34-d.a
libboost_regex-gcc34-d.so
libboost_regex-gcc34-mt-1_34.a
libboost_regex-gcc34-mt-1_34.so
libboost_regex-gcc34-mt-1_34.so.1.34.0
libboost_regex-gcc34-mt.a
libboost_regex-gcc34-mt-d-1_34.a
libboost_regex-gcc34-mt-d-1_34.so
libboost_regex-gcc34-mt-d-1_34.so.1.34.0
libboost_regex-gcc34-mt-d.a
libboost_regex-gcc34-mt-d.so
libboost_regex-gcc34-mt.so
libboost_regex-gcc34.so

Also, I tried with all above *.a by stripping "lib" &
.* from their name. However I can get messages like

/usr/include/boost/regex/v4/basic_regex.hpp:338:
undefined reference to `boost::reg_expression<char,
boost::regex_traits<char>, std::allocator<char>
>::reg_expression(std::allocator<char> const&)'

Do you think I have made some mistake during build.
Following were the steps followed
=> gunzip boost_1_34_0.tar.gz 
=> tar -xvf boost_1_34_0.tar 
=> cd boost_1_34_0
=> ./configure
--prefix=/home/ChandanNilange/work/boost/ 
--with-libraries=regex
=> make install

Regards,
Chandan
