[OS] Linking with OS API

[Kipp Martin]

Hi Pete:


A few questions.

1) Did you first run configure and then test as described in


http://www.coin-or.org/OS/documentation/node11.html

Did you pass the unitTest?

If you are going to try something like the above, first do a

make install

it will put all of the necessary header files in an include file for you in

COIN-OS/include

and the libraries in

COIN-OS/lib

See Step 5 of the above link.


What I suggest you do is look at one of our examples. In particular, if 
you now get the trunk version of OS

svn co https://projects.coin-or.org/svn/OS/trunk COIN-OS

there is a good example that you will get in

COIN-OS/OS/examples/instanceGenerator

that will do exactly what you are trying to do in your int main() above. 
  Configure will generate a makefile for this example and you should be 
able to edit a few lines of the makefile where indicated to get things 
going.

See

http://www.coin-or.org/OS/documentation/node77.html

Let me know how this goes.

Thanks
