Hi Boost Experts, I am using boost geometry headers in our code. While compiling the code on HPUX IA64 with +std=c++11 and +stl=gnu flags, we get a cryptic assembler error. Appreciate any help to understand/debug this error. The testcase: *bash-4.3$ cat geom1.cpp* #include #include #include #include typedef boost::geometry::model::pointboost::geometry::degree > point_t; typedef boost::geometry::model::linestring linestring_t; typedef boost::geometry::model::multi_linestring multilinestring_t; using namespace std; template bool Inside(string one, string two) { T objOne; S objTwo; bool inside = false; boost::geometry::read_wkt(one, objOne); boost::geometry::read_wkt(two, objTwo); inside = boost::geometry::within(objOne, objTwo); return inside; } bool Inside(string wktOne, string wktTwo) { bool inside; inside = Inside(wktOne, wktTwo); return inside; } Compilation command: *bash-4.3$ aCC -c +DD64 +std=c++11 +stl=gnu -I geom1.cpp* *ASM_BACKEND fatal error: symbol* `_ZN5boost8geometry6detail7overlay27get_turn_info_linear_linearINS1_6relate5turns13assign_policyILb1EEEE22append_opposite_spikesILNS3_INS6_ILb1EEEE14append_versionE1ENS2_9turn_infoINS0_5model5pointIdLm2ENS0_2cs10geographicINS0_6degreeEEEEENS0_13segment_ratioIdEENS2_21turn_operation_linearINSB_IdLm2ENSD_ISE_EEEENSF_IdEEEENS_5arrayINSG_INSB_IdLm2ENSD_ISE_EEEENSF_IdEEEELm2EEEEENS2_17intersection_infoINS1_9get_turns29unique_sub_range_from_sectionILb0ENS0_7sectionINSA_3boxINSB_IdLm2ENSD_ISE_EEEEEELm2EEENSB_IdLm2ENSD_ISE_EEEENS0_22ever_circling_iteratorIN9__gnu_cxx17__normal_iteratorIPKNSB_IdLm2ENSD_ISE_EEEESt6vectorINSB_IdLm2ENSD_ISE_EEEESaINSB_IdLm2ENSD_ISE_EEEEEEEEEENS0_8strategy12intersection18spherical_segmentsIvEENS1_17no_rescale_policyEEENSK_ILb0ENSL_INSM_INSB_IdLm2ENSD_ISE_EEEEEELm2EEENSB_IdLm2ENSD_ISE_EEEENSN_INSP_ISR_SS_INSB_IdLm2ENSD_ISE_EEEESaINSB_IdLm2ENSD_ISE_EEEEEEEEEENSV_IvEESW_EENSB_IdLm2ENSD_ISE_EEEENSV_IvEESW_EESt20back_insert_iteratorISS_INS9_INSB_IdLm2ENSD_ISE_EEEENSF_IdEENSG_INSB_IdLm2ENSD_ISE_EEEENSF_IdEEEENSH_INSG_INSB_IdLm2ENSD_ISE_EEEENSF_IdEEEELm2EEEEESaINS9_INSB_IdLm2ENSD_ISE_EEEENSF_IdEENSG_INSB_IdLm2ENSD_ISE_EEEENSF_IdEEEENSH_INSG_INSB_IdLm2ENSD_ISE_EEEENSF_IdEEEELm2EEEEEEEEEEbRT0_RKT1_T2_' already defined Thanks, Ananta
