boost_regex 1.34.0 uses ICU library without linking to it

[bero@…]

g++ test.cpp -lboost_regex

results in

/usr/lib/libboost_regex.so: undefined reference to `icu_3_4::Collator::createInstance(icu_3_4::Locale const&, UErrorCode&)' /usr/lib/libboost_regex.so: undefined reference to `icu_3_4::Locale::Locale()' /usr/lib/libboost_regex.so: undefined reference to `u_tolower_3_4' /usr/lib/libboost_regex.so: undefined reference to `icu_3_4::Locale::~Locale()' /usr/lib/libboost_regex.so: undefined reference to `u_isspace_3_4' /usr/lib/libboost_regex.so: undefined reference to `icu_3_4::Locale::Locale(icu_3_4::Locale const&)' /usr/lib/libboost_regex.so: undefined reference to `u_isblank_3_4' /usr/lib/libboost_regex.so: undefined reference to `u_digit_3_4' /usr/lib/libboost_regex.so: undefined reference to `u_charType_3_4' /usr/lib/libboost_regex.so: undefined reference to `u_charFromName_3_4'

Of course a simple workaround is to use

g++ test.cpp -lboost_regex -licu, but that linkage should really be in the library itself, it makes using it easier and allows prelinking to work correctly.

This (obviously incorrect because it assumes icu lives in /usr/lib) patch fixes it for me - maybe it can give a hint on what's going wrong.

If you run the build Jamfile with the -d2 option you should see something like "-licui18n -licuuc" added to the link command line, is this not enough?

Please reopen if you can provide more info: this works for me OK as is.
