Hi, I am trying to compile my project on 32 bit AIX 5.2L with GCC (version4.0.0) I m compiling shared libraries as: g++-o shr.o -Wl,-bloadmap:map.txt -shared -Wl,-bnoquiet -Wl,-bnoentry -Wl,-bexpall -Wl,-bE:/Pheft/source/cryptolink/apidll/esmapi.exp jesm.o jretry.o csa8kesm.o tcpipesm.o asyncesm.o esmapi.o recvq.o varsupt.o esmlist.o -L/Pheft/source_obj/AIX_00C2BC404C00/lib/ -ldl -Wl,-bstatic -lsupt_unix_s -Wl,-bdynamic -lpthread -Wl,-bstatic -lcptrlist_s -ljesmcfg_s -Wl,-bdynamic -Wl,-brtl -Wl,-berok and the program as : g++ -o cryptest tt.o -L/Pheft/source_obj/AIX_00C2BC404C00/lib/ -lesmapi -Wl,-bstatic -lcptrlist_s -ljesmcfg_s -lsupt_unix_s -Wl,-bdynamic -lpthread -Wl,-brtl -Wl,-berok but when I am running the program cryptest: bash-3.00# ./cryptest exec(): 0509-036 Cannot load program ./cryptest because of the following errors: rtld: 0712-001 Symbol _ZTVN10__cxxabiv117__class_type_infoE was referenced from module cryptest(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol _ZTVN10__cxxabiv120__si_class_type_infoE was referenced from module cryptest(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol _Z12RunCallBackpPcS_j was referenced from module cryptest(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol _Z12RunCallBack1Pcij was referenced from module cryptest(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol _Z11RunCallBackPcj was referenced from module cryptest(), but a runtime definition of the symbol was not found. The dependecny map of cryptest is : bash-3.00# ldd cryptest cryptest needs: ./libesmapi.a(shr.o) /usr/lib/libpthread.a(shr_comm.o) /usr/lib/libpthread.a(shr_xpg5.o) /opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.0.0/libstdc++.a(libstdc++.so.6) /opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.0.0/libgcc_s.a(shr.o) /usr/lib/libc.a(shr.o) /usr/lib/librtl.a(shr.o) /usr/lib/libdl.a(shr.o) /usr/lib/libpthreads.a(shr_comm.o) /unix /usr/lib/libcrypt.a(shr.o) Can anybody help me out.
