boost - Ubuntu oneiric 上的 g++ 和 boost 链接器错误

Question

升级后出现以下错误。我无法弄清楚它有什么问题。据我所知，它应该可以工作。

$ make 2>&1 | head

根据手册页，解决方案涉及更改链接顺序。问题是它曾经可以在旧版本的 g++ 上正常工作......

$ make
g++ -I/usr/include/boost -MM ./YYY.cc ./main.cc ./myClass.cc > buildfiles.d
g++ -ansi -O2 -Wall -I/usr/include/boost   -c -o main.o main.cc
g++ -ansi -O2 -Wall -I/usr/include/boost   -c -o myClass.o myClass.cc
g++ -o prog -ansi -O2 -Wall -I/usr/include/boost  ./YYY.o ./main.o ./myClass.o -lstdc++ -L/usr/lib -lboost_program_options -lboost_thread
