boost filesystem library files can not be linked
My ubuntu is 10.04. boost was installed from apt-get.
I compiled the following code. But the library is not available to
link. Would you please let me know how what link option I should use?
$ cat main.cpp
#include
I run boost on Windows but the first things to check should be similar:
1. Does apt-get get the compiled version of boost or just get the
sources ? Are the compiled shared and lib files there ?
2. In case the files are there, is the directory included in the
search path for the linker ?
Best regards,
Mau.

In addition to the boost_filesystem lib, you also need to link against the boost_system lib. I believe this should solve your problem. Regards, Mostafa

If I use g++, I should compile it like this, right?
g++ -o main.exe main.cpp -lboost_filesystem -lboost_system
You may also need to specify the -L option if your boost libs are not in
the linkers default search path. Something like this:
g++ -o main.exe main.cpp -L
