hi,
 i've tried to build xerces-c 3.1.1 with icu support.

 first, i compiled icu 4.8.1 (OUT_DIR 'points' to /home/nikola/vincorex_development):

 ./runConfigureICU Linux --prefix=${OUT_DIR}
 make && make install

 ICU is built and installed in ${OUT_DIR}

 now i've tried to build xerces-3.1.1:
 ./configure --prefix=${OUT_DIR} --disable-rpath --enable-msgloader-inmemory \
--enable-transcoder-icu --with-icu=${OUT_DIR}  make && make install

 xerces is built and installed in ${OUT_DIR}; but ldd on resulting xerces-c.so does \
not show dependency on ICU located in ${OUT_DIR}. LD_LIBRARY_PATH is set to \
${OUT_DIR}/lib.  after few (re)tries, i tried on older compiler (4.5.2) and \
everything went fine.

 problematic part is as follows:

 (from config.log)
........................
 g++ -o conftest -g -O2 -I/home/nikola/vincorex_development/include -lpthread -ldl \
-lm -L/home/nikola/vincorex_development/lib -licui18n -licuuc -licudata -lpthread \
-ldl -lm  *conftest.cpp* -lnsl -lpthread  /tmp/ccxSIK6a.o: In function `main':
 /tmp/conftest.cpp:109: undefined reference to `ucnv_open_48'
 collect2: ld returned 1 exit status
........................

 reason for this check to fail lies is parameter ordering; for example this line runs \
fine:

g++ -o conftest -g -O2 -I/home/nikola/vincorex_development/include  *conftest.cpp* \
-lpthread -ldl -lm -L/home/nikola/vincorex_development/lib -licui18n -licuuc \
-licudata -lpthread -ldl -lm -lnsl -lpthread

this is because i've moved conftest.cpp before library search part (if i'm not \
mistaking, this conforms to GCC)

 i've found this on hard way, hope it will help to someone else. since i dont know \
autotools, i did not wanted to change autofiles, rather i created virtual machine \
hosting older Ubuntu with older GCC and build there

 best regards
 nikola
