在Ubuntu oneiric上g ++和boost鏈接器錯誤

Question

升級後出現以下錯誤。我無法弄清楚它有什麼問題。它應該盡我所能地工作。

解決方案涉及更改鏈接的順序，根據手冊頁。問題是，它採用做工精細用較舊版本的g ++的...

$ 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
