boost - g++ y aumenta el error del enlazador en Ubuntu oneiric

icc

Question

Recibo los siguientes errores después de una actualización. No puedo entender lo que está mal con eso. Debería funcionar tanto como yo pueda ver.

$ make 2>&1 | head

La solución implicaba cambiar el orden de vinculación, según la página del manual. El caso es que solía funcionar bien con una versión anterior de g ++ ...

$ 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
