Hi all,
I'm trying some boost library examples, on amd64, using -current. When
building with clang it works ok, but using eg++ results in load-time
failure:
snaptest66$ timlibs="-I/usr/local/include -L/usr/local/lib
-lboost_timer"
snaptest66$ ec++ -o tcs.fastgx $timlibs -Ofast timed_chaotic_system.cpp
snaptest66$ ./tcs.fastgx
tcs.fastgx:/usr/local/lib/libestdc++.so.19.0: /usr/lib/libc++abi.so.1.0

...etc....about a dozen similar symbols....

which is to say both clang libc++ and libc++abi and gcc libestdc++ are
linked.
Using purely clang c++ works ok:
snaptest66$ c++ -o tcs.fastx $timlibs -Ofast timed_chaotic_system.cpp
snaptest66$ ./tcs.fastx
100000 0.905083 1.28992e-05 -14.5717
...etc...known good output...
Is this even possible (should I stop now) or is it something I am
doing incorrectly?
thanks
John
