Hello, I'm trying to build some basic Boost.Locale Jam file on base of Boost.Regex one, however... I can't even build Boost.Regex with ICU at all. Version 1.43 ------------ Debian, ICU 3.8 installed in regular place /usr/lib/libicu*.so Build: bjam -d+2 -sHAVE_ICU=1 stage Shows that the build is done with ICU (i.e. -DBOOST_HAS_ICU=1 in command line of gcc) However when afterward I check ldd stage/lib/libboost_regex.so It shows no evidence of linking with ICU. Version 1.44 ------------ Build: bjam -d+2 -sHAVE_ICU=1 stage Shows that the build is done without ICU! i.e. -DBOOST_HAS_ICU=1 in command line of gcc is NOT defined. And of course ldd shows the same Even if I specify bjam -d+2 -sHAVE_ICU=1 -sICU_PATH=/usr stage Or try to use ICU4.4 installed on other location bjam -d+2 -sHAVE_ICU=1 -sICU_PATH=/opt/icu44 stage Same result. I don't understand how can I actually get the library (especially recent) built with ICU. Artyom
