Hi,
 there I tried to build Boost with ICU-support under Windows from source.

My Question is, why does the build-sep find ICU header files to compile
the
file "has_icu_test.o" but the linker step failes with "undefined reference
to `u_charFromName_52'"

MinGW GCC/G++ is installed under C:\MinGW.
With this compiler suite I build ICU (version 52.1) from source and
installed it into the directory C:\MinGW-build.

my call to build Boost was (all in one line)

b2 -d+2 -a -j7 -sICU_PATH=C:\MinGW-build -sICU_LINK="
-LC:/MinGW-build/lib"
--without-mpi --without-context --without-coroutine --reconfigure
--debug-configuration --debug-building
--prefix=C:\MinGW-build-tmp\MinGW-build
--stagedir=C:\MinGW-build-tmp\boost-tmp\stage
--build-dir=C:\MinGW-build-tmp\boost-tmp --build-type=complete
include=C:\MinGW-build\include;C:\MinGW\include address-model=32
toolset=gcc
stage
