Hi all, I am trying to compile Boost on following Solaris machine: => SunOS isdbuild9 5.8 Generic_108528-18 sun4u sparc SUNW,Sun-Fire-480R I have used following command to build boost : => ../boost-jam-3.1.12/bin.solaris/bjam -sTOOLS=gcc --libdir=./lib stage I have got following error, during compilation. ======================================================================== =================== gcc-C++-action bin/boost/libs/serialization/build/libboost_wserialization.a/gcc/debug/u tf8_codecvt_facet.o /vob/wibb_test/tools/cots/boost_1_33_1/libs/serialization/src/utf8_codec vt_facet.cpp:8:2: #error "wide char i/o not supported on this platform" set -e "g++" -c -Wall -ftemplate-depth-255 -DBOOST_LIB_DIAGNOSTIC=1 -g -O0 -fno-inline -Wno-non-virtual-dtor -Wno-ctor-dtor-privacy -I"bin/boost/libs/serialization/build" -I "/vob/wibb_test/tools/cots/boost_1_33_1" -o "bin/boost/libs/serialization/build/libboost_wserialization.a/gcc/debug/ utf8_codecvt_facet.o" "/vob/wibb_test/tools/cots/boost_1_33_1/libs/serialization/build/../src/ utf8_codecvt_facet.cpp" "/apps/public/bin/objcopy" --set-section-flags .debug_str=contents "bin/boost/libs/serialization/build/libboost_wserialization.a/gcc/debug/ utf8_codecvt_facet.o" ...failed gcc-C++-action bin/boost/libs/serialization/build/libboost_wserialization.a/gcc/debug/u tf8_codecvt_facet.o... gcc-C++-action bin/boost/libs/serialization/build/libboost_wserialization.a/gcc/debug/b asic_text_wiprimitive.o /vob/wibb_test/tools/cots/boost_1_33_1/libs/serialization/src/basic_text _wiprimitive.cpp:14:2: #error "wide char i/o not supported on this platform" ======================================================================== =================== I tried to compile with following command too, but somehow it does not skip compilation of boost_serialization library: => ../boost-jam-3.1.12/bin.solaris/bjam -sTOOLS=gcc --libdir=./lib --without-boost_serialization stage Please let me know if you have similar issue before and aware of any solution.
