Boost.Regex with icu/unicode support

Question

How to build Boost.Regex with icu/ unicode support? My compiler is GCC, and IDE is Eclipse C++. How to configure binary files with Eclipse? I tried to do this "bjam --sHAVE_ICU=1 toolset=gcc". But it did not work. When i check if icu support is enable with "bjam -has_icu", i still get "has icu builds : no".

Answer 1

I build Boost against ICU using -sICU_PATH=<icuRoot> and -sICU_LINK="-L<icuLibDir>".

I've seen Boost fail to properly detect ICU as well, and have needed to patch the file has_icu_test.cpp (simply return 0 from it's main() function). This will work if you know everything else is set up properly.

Solved the problem by adding directly include path of include ICU directory to cflags when executing b2. For instance:

./b2 --with-regex
cflags="-O0 -I\"$ICU_PATH/include\"

You also may need to add path of ICU lib and moreover full paths to libs to linker. Something like this:

export ICU_LINK="-L\"$ICU_PATH/lib\" -l\"$ICU_PATH/lib/libicudata.a\" -l\"$ICU_PATH/lib/libicui18n.a\" -l\"$ICU_PATH/lib/libicuuc.a\""
./b2 --with-regex
cflags="-O0 -I\"$ICU_PATH/include\"
-sICU_LINK=$ICU_LINK \
