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

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

Hi,

I am compiling a very simple application using boost filesystem. However it is giving following error message:

"undefined reference to `boost::filesystem2::no_check(std::basic_string const&)'"

Here is the simple application source: --------------------------------Sample application source: #include #include

int main() { std::string m_FileName(boost::filesystem::path("testfile1.txt", boost::filesystem::no_check).native_file_string());

printf("Testboost.....%s\n", m_FileName.c_str()); return 0; } --------------------------------

More Details: Libraries being used: libboost_filesystem-gcc41-mt-1_44.a libboost_system-gcc41-mt-1_44.a

Boost version: 1.44.0

Boost was build using command: bjam --build-type=complete --layout=versioned

Operating System: Linux CentOS5.2

Any help in this regard will be appreciated.
