Hi, I have a problem to compile Boost 1.39 or 1.40 ro 1.41 on Solaris Sparck with gcc 4.2.4. I am tried to compile with bjam and witj Cmake but I will get the same assembler message about illegal operands error. I noticed that when I defined BOOST_SP_USE_PTHREADS everything compiled fine until I tried to compile my software using Boost. Then I got the same assembler message about illegal operands. Do You have any advice? Best Regards, Teemu Here is the error while running make: ~/boost-1.41.0.cmake0/build % make [ 0%] Building CXX object libs/date_time/src/CMakeFiles/ boost_date_time-mt-shared.dir/gregorian/greg_month.cpp.o /var/tmp//ccXu6PKl.s: Assembler messages: /var/tmp//ccXu6PKl.s:580: Error: Illegal operands /var/tmp//ccXu6PKl.s:595: Error: Illegal operands /var/tmp//ccXu6PKl.s:8504: Error: Illegal operands make[2]: *** [libs/date_time/src/CMakeFiles/boost_date_time-mt- shared.dir/gregorian/greg_month.cpp.o] Error 1 make[1]: *** [libs/date_time/src/CMakeFiles/boost_date_time-mt- shared.dir/all] Error 2 make: *** [all] Error 2 Here is the generated configuration output from Cmake: tes@kielo <arkki_Z4.4-481_0/HAR1>:~/utils/boost-1.41.0.cmake0/build % cmake ../. -- -- Boost.CMake version = 1.41.0.cmake0 -- Boost compiler = gcc -- Boost toolset = gcc42 -- Boost platform = sunos -- Build name = gcc-4.2.4-sunos -- -- Looking for (optional) dependencies on the system -- -- BZip2: -- BZIP2_INCLUDE_DIR = /usr/include -- BZIP2_DEFINITIONS = -- BZIP2_LIBRARIES = /usr/lib/libbz2.so -- -- Doxygen: -- DOXYGEN_EXECUTABLE = /C2/tools/utils/bin/doxygen -- DOXYGEN_DOT_FOUND = YES -- DOXYGEN_DOT_EXECUTABLE = /C2/tools/utils/bin/dot -- DOXYGEN_DOT_PATH = /C2/tools/utils/bin -- -- Expat: -- Expat not found, some libraries or features will be disabled. -- See the documentation for Expat or manually set these variables: -- EXPAT_INCLUDE_DIR = EXPAT_INCLUDE_DIR-NOTFOUND -- EXPAT_LIBRARIES = -- -- ICU: -- Disabled since WITH_ICU=OFF -- -- MPI: -- MPI not found, some libraries or features will be disabled. -- See the documentation for MPI or manually set these variables: -- MPI_INCLUDE_PATH = MPI_INCLUDE_PATH-NOTFOUND -- MPI_COMPILE_FLAGS = -- MPI_LINK_FLAGS = -- MPI_LIBRARIES = MPI_LIBRARY-NOTFOUND -- -- Python: -- Disabled since WITH_PYTHON=OFF -- -- Xsltproc: -- XSLTPROC_EXECUTABLE = /usr/bin/xsltproc -- XSLTPROC_FLAGS = --xinclude -- -- Valgrind: -- Disabled since WITH_VALGRIND=OFF -- -- ZLib: -- ZLIB_INCLUDE_DIR = /usr/include -- ZLIB_LIBRARIES = /usr/lib/libz.so -- -- Install include dir: = include/boost-1.41.0 -- Install lib dir: = lib/boost-1.41.0 -- -- Reading boost project directories... -- -- + preprocessor -- + concept_check -- + property_map -- + config -- + mpl -- + type_traits -- + function -- + iterator -- + smart_ptr -- + exception -- + utility -- + integer -- + detail -- + static_assert -- + tuple -- + function_types -- + fusion -- + typeof -- + proto -- + intrusive -- + logic -- + numeric -- + xpressive -- + optional -- + tokenizer -- + io -- + bind -- + date_time -- + thread -- + regex -- +-- ICU (unicode) not available, disabling support. -- + algorithm -- + range -- + foreach -- + array -- + functional -- + unordered -- + pool -- + spirit -- + variant -- + serialization -- + format -- + math -- + multi_index -- + any -- + random -- + graph -- + python -- +-- disabled since PYTHON_FOUND is false -- + parameter -- + accumulators -- + system -- + asio -- + circular_buffer -- + ptr_container -- + assign -- + bimap -- + compatibility -- + conversion -- + crc -- + timer -- + test -- + disjoint_sets -- + dynamic_bitset -- + filesystem -- + interprocess -- + flyweight -- + gil -- + mpi -- +-- MPI not found, disabling. -- + graph_parallel -- +-- MPI not found, disabling. -- + iostreams -- + lambda -- + multi_array -- + program_options -- + rational -- + signals -- + signals2 -- + statechart -- + tr1 -- + units -- + wave -- -- Reading boost project TEST directories... -- -- -- Skipping config of tools since BUILD_TOOLS is "NONE" -- -- Configuring done -- Generating done -- Build files have been written to: /home/tes/utils/ boost-1.41.0.cmake0/build
