&gt; Here is the command I used to build regex with icu support on linux machine.<br />&gt; I specified where is the icu library I installed instead
of system library<br />&gt; directory.<br />&gt; <br />&gt; ./bjam --prefix=/home/qhwang/mylibs/boost/ --with-regex<br />&gt;
--build-dir=/tmp/boost_build/ --build-type=complete -sHAVE_ICU=1<br />&gt; -sICU_PATH=/home/qhwang/mylibs/icu/  install<br />&gt; The regex library
I built is dependent on icu library. If you don't specify<br />&gt; HAVE_ICU=1 then you don't need ICU_PATH either. Then the regex will not be<br
/>&gt; dependent on icu library. You can't create a u32regex by calling<br />&gt; make_u32regex to match or search unicode string. Hope my explain
is helpful.<br />&gt; <br /><br />Now I'm correctly building 64-bit versions of the libraries, but they are still installed<br />in /usr/local/lib.
Is there a way to tell the installer to use /usr/local/lib64 instead?<br /><br />Thanks,<br /><br />Juan
