The problems described below appeared after I upgraded to the latest
versions of the cygwin release. It disappeared when I went back to gcc-2.95.3,
leaving all the other utilities at the latest version. This suggests to me the
problem lies in gcc-3.2.1, or in how I have it configured.
Why won't
gcc simp.cpp -o simp
compile the incredibly simple program below without generating e-messages like
/DOCUME~1/Mark/LOCALS~1/Temp/ccRtp1xR.o(.eh_frame+0x11):simp.cpp: undefined reference
to `___gxx_personality_v0'
collect2: ld returned 1 exit status
Why must I replace gcc with g++ or c++ after upgrading from gcc-2.95.3-5 to
3.2.1 ?
Are error messages like
/DOCUME~1/Mark/LOCALS~1/Temp/ccBuHJFC.o(.text+0x948):anv.cpp: undefined reference to
`operator new(unsigned)'
/DOCUME~1/Mark/LOCALS~1/Temp/ccBuHJFC.o(.text+0x979):anv.cpp: undefined reference to
`__cxa_begin_catch'
/DOCUME~1/Mark/LOCALS~1/Temp/ccBuHJFC.o(.text+0x9a5):anv.cpp: undefined reference to
`__cxa_end_catch'
in response to compiling a slightly more complicated cpp program with gcc
related, or due to something else? My slightly more complicated program will
compile if I replace gcc with g++, but the compiled program bombs immediately.
Is there a simple fix other than using gcc-2.95.3-5 instead of 3.2-1?
Thank you, Mark Schoenberg
