[Coin-discuss] problems building in Cygwin on Windows XP

[Skylab Gupta]

Hi,

I downloaded the COIN_2005Feb28 package recently. I am working in the
Windows XP environment (with cygwin), and my gcc version is 3.3.1. I am
also using the LP solver CLP.

With these settings, I successfully managed to build the following
components (using the 'make' command): Clp, Cgl, Coin and Osi.
But now, when I try to 'make unitTest' (in the Osi folder), I get the
following errors:

-------------------------------------

I am a beginner to COIN software, so any help is appreciated.

Thanks,
