[classad-users] Please help

[Xin Tang <xtang3@xxxxxxxx>]

Hi all,

I am a new user to classAds and I wish someone could give me some helps to get start with this language. The library I am using is Version 1.0.7 and I tried to run the given file sample.cpp as the README file suggests, but I got some errors which I have no clue how to fix. Below is the command I used(it includes some flags required by the tutorial(http://www.cs.wisc.edu/condor/classad/c++tut.html#prelim)):

g++ classads-1.0.7/sample.cpp -I./include -L./lib

Here are the error messages I got:

/tmp/ccsnP3sf.o: In function `main':

Thank you in advance for any help you can provide.
