I'm getting some annoying errors when compiling some of the libraries of Boost 1.33.0 with Intel Compiler 9.0 (icpc (ICC) 9.0 20050811) under Linux. Here is what happens when I try to compile (again after a first try which failed to update all targets): ----------------------------------------------------------------------------------- ../boost-jam-3.1.11-1-linuxx86/bjam -sTOOLS=intel-linux --prefix=/RQusagers/delallea/local --builddir=/RQexec/delallea/boost_1330_90 -sPYTHON_VERSION=2.4 --with-python-root=/usr/network.ALTIX/python-2.4.1 -sINTEL_VERSION=90 -sINTEL_PATH=/opt/intel/compiler90 install Building Boost.Regex with the optional Unicode/ICU support disabled.

Now, the important detail: I have in my icpc.cfg the following line: -I/opt/intel/compiler90/include/c++ which forces the Intel compiler to (preferably) use its own includes. Otherwise it uses the g++ standard includes and (at least for the file above) compilation works fine. But I would really prefer to be able to compile Boost using only the Intel code (especially since I need this line in my icpc.cfg for some other non-Boost stuff to compile). Then when compiling the regex library I have other errors. Here is an example of what happens with a specific compile line (here I cleaned my icpc.cfg file): ----------------------------------------------------------------------------------- icpc -I/opt/intel/compiler90/include/c++ -c -w1 -DNDEBUG -DNDEBUG -O3 -openmp -I"/RQexec/delallea/boost_1330_90/bin/boost/libs/regex/build" -I"/RQMNT/exec1/lisa/delallea/boost_src/boost_1_33_0" -o "/RQexec/delallea/boost_1330_90/bin/boost/libs/regex/build/libboost_regex.a/intel-linux/release/threading-multi/instances.o" "/RQMNT/exec1/lisa/delallea/boost_src/boost_1_33_0/libs/regex/build/../src/instances.cpp" /RQMNT/exec1/lisa/delallea/boost_src/boost_1_33_0/boost/regex/v4/instances.hpp(84): error #803: function "boost::match_results<BidiIterator, Allocator>::match_results(const boost::match_results<BidiIterator, Allocator> &) [with BidiIterator=const char *, Allocator=std::vector<boost::sub_match<const char *>, std::allocator<boost::sub_match<const char *>>>::allocator_type]" explicitly instantiated more than once template class BOOST_REGEX_DECL match_results< std::basic_string<BOOST_REGEX_CHAR_T>::const_iterator >; ----------------------------------------------------------------------------------- There are many errors like this one. Again, if I remove the include command -I/opt/intel/compiler90/include/c++ it works fine. Also if I use the intel 8.0 includes it works fine (but not intel 8.1). Any help fixing these errors (actually, mainly the regex one, as this is the library I really need) will be much appreciated :) -- Olivier
