• set the following environment variables & create the directories as shown below:
  
  setenv TZ PST8PDT
  setenv ICUROOT <root directory of ICU source>
  setenv ICU_DATA $ICUROOT/source/data/
  setenv XERCESCROOT <root directory of xerces source>

Building ICU 2.2 on Solaris 10 x86
______________________________

1. Download ICU 2.2 source code & 2.2 patch from:
   
   ftp://www-126.ibm.com/pub/icu/2.2/icu-2.2.tgz
   ftp://www-126.ibm.com/pub/icu/2.2/icu-2.2-patch.zip
   
   
2. cd $ICUROOT/source
   
3. chmod +x runConfigureICU configure install-sh
   
4. ./runConfigureICU SOLARISX86 --disable-64bit-libs --enable-layout --prefix=<installation-directory>
   (by default layout will be disabled)
   
5. Edit icudefs.mk:
   i) Add -lCrun link flag to DEFAULT_LIBS
   ii) Add -L$(top_builddir)/data/out/build to LIBICUDT
   
   
   104c104
   < DEFAULT_LIBS = -lpthread -lm -lCrun
   ---
   > DEFAULT_LIBS = -lpthread -lm
   154c154
   < LIBICUDT= -L$(top_builddir)/data/out -L$(top_builddir)/data/out/build -L$(top_builddir)/stubdata
   
   -l$(ICUPREFIX)data$(ICULIBSUFFIX)$(SO_TARGET_VERSION_SUFFIX)
   ---
   > LIBICUDT= -L$(top_builddir)/data/out -L$(top_builddir)/stubdata
   
   -l$(ICUPREFIX)data$(ICULIBSUFFIX)$(SO_TARGET_VERSION_SUFFIX)
   
   Edit runConfigureICU & configure files and remove the "-g" flag for RELEASE builds
   
   
6. ./runConfigureICU SOLARISX86 --disable-64bit-libs --enable-layout --prefix=<installation-directory>
   
7. gmake
   
8. gmake check (optional)
   
9. gmake install
   
   

_______________

Building Xerces 2.1
_______________

1. Download the source for Xerces 2.1 from:
   http://archive.apache.org/dist/xml/xerces-c/Xerces-C_2_1_0/xerces-c-src2_1_0.tar.gz
   
   
2. Copy the unicode header files from ICU source distribution. Please note that Solaris 10 ships ICU 2.1 and failing to copy
   the headers as shown below may result in undefined symbol errors:
   
   cp $ICUROOT/source/common/unicode/*.h $ICUROOT/include/unicode/
   cp $ICUROOT/source/common/icucfg.h $ICUROOT/include/icucfg.h
   
   
3. cd $XERCESCROOT/src/xercesc
   pushd $ICUROOT/lib
   
   foreach i ( $ICUROOT/lib/sol/release/*.so*)
   ln -s $i
   end
   
   popd
   
   
4. Fix needed to allow compilation for DOMDocumentImpl.cpp
   
   cp $XERCESCROOT/src/xercesc/dom/impl/DOMDeepNodeListImpl.hpp $XERCESCROOT/include/xercesc/dom/impl
   cp $XERCESCROOT/src/xercesc/dom/impl/DOMDeepNodeListPool.hpp $XERCESCROOT/include/xercesc/dom/impl
   
   
5. Edit Makefile.incl:
   Add -lCstd link flag to all ALLLIBSs
   
   138c138
   < ALLLIBS = -mt -licuuc -licudata ${LIBS}
   ---
   > ALLLIBS = -mt -licuuc -licudata -lCstd ${LIBS}
   140c140
   < ALLLIBS = -mt ${LIBS}
   ---
   > ALLLIBS = -mt -lCstd ${LIBS}
   144c144
   < ALLLIBS = -mt -licuuc -licudata ${LIBS}
   ---
   > ALLLIBS = -mt -licuuc -licudata -lCstd ${LIBS}
   
   
6. runConfigure -psolaris -ccc -xCC -minmem -nsocket -ticu -rpthread -z-DXERCES_TMPLSINC -C --prefix=<installation-directory> -d
   Note: -d builds a debug build; if needs an optimized release build, remove -d.
   
7. gmake
   
8. gmake install
   
   

** Note **

Failing to make the changes as mentioned above leads to undefined symbols

eg.,
