Hi All I was successful in getting gcc 4.3.2 compiled and installed on AIX 5.3. I used the following configure to get that : /cots/gnu/gcc-4.3.2/configure --prefix=/usr/local --with-gmp=/cots/gnu/gmp-4.2.4 --with-mpfr=/cots/gnu/mpfr-2.3.2 --enable-shared --disable-nls --enable-__cxa_atexit --enable-threads=aix --disable-multilib I am using AIX linker and not the gnu ld. When compiling and linking c++ applications with g++, I get the following errors : ld: 0711-317 ERROR: Undefined symbol: __cxa_pure_virtual ld: 0711-317 ERROR: Undefined symbol: vtable for __cxxabiv1::__si_class_type_info ld: 0711-317 ERROR: Undefined symbol: vtable for __cxxabiv1::__vmi_class_type_info ld: 0711-317 ERROR: Undefined symbol: vtable for __cxxabiv1::__class_type_info ld: 0711-317 ERROR: Undefined symbol: __gxx_personality_v0 ld: 0711-317 ERROR: Undefined symbol: .operator delete[](void*) ld: 0711-317 ERROR: Undefined symbol: .operator delete(void*) ld: 0711-317 ERROR: Undefined symbol: .__cxa_allocate_exception ld: 0711-317 ERROR: Undefined symbol: .__cxa_throw ld: 0711-317 ERROR: Undefined symbol: ._Unwind_Resume ld: 0711-317 ERROR: Undefined symbol: .std::terminate() ld: 0711-317 ERROR: Undefined symbol: .std::ios_base::Init::Init() ld: 0711-317 ERROR: Undefined symbol: .std::ios_base::Init::~Init() ld: 0711-317 ERROR: Undefined symbol: .operator new(unsigned long) ld: 0711-317 ERROR: Undefined symbol: .__cxa_begin_catch ld: 0711-317 ERROR: Undefined symbol: .__cxa_end_catch ld: 0711-317 ERROR: Undefined symbol: .__register_frame_info_table ld: 0711-317 ERROR: Undefined symbol: .__deregister_frame_info ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information. collect2: ld returned 8 exit status Any pointers on how to fix it. I set the LIBPATH variable to point to the /usr/local/lib where I had installed the gcc related libraries. Thanks in advance. With Regards Vardhan
