Re: [Boost-users] boost 1.44.0 undefined reference to boost::filesystem2::no_check

The command that I used was:

 g++ -I[pathtoboostrootdirectory] -L[pathtoboostlibraries] testboost.cpp -o
testboost -lboost_system-gcc41-mt-1_44 -lboost_filesystem-gcc41-mt-1_44

g++ (GCC) version that I am using is: 4.1.2 20080704

More Observations:
if I use gcc optimization flag i.e. -O or -O1 or -O2 or -O3, then the
application is builds successfully. here is the command that I use:

 g++ -O -I[pathtoboostrootdirectory] -L[pathtoboostlibraries] testboost.cpp
-o testboost -lboost_system-gcc41-mt-1_44 -lboost_filesystem-gcc41-mt-1_44

thanks

Hi,

it seems to me that the linker is missing the library (e.g.
-lboost_filesystem)
Could you please send the command-line you use to compile the simple
program?

Best,

Cedric
