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

[Ted Ralphs]

If you are planning to use SYMPHONY, then edit the file 
COIN/SYMPHONY/Makefile and set the variable ARCH=CYGWIN. This should 
allow SYMPHONY to compile. If you don't plan to use SYMPHONY at all, you 
can also prevent it from being compiled by editing the file 
COIN/Makefiles/Makefile.location and commenting out the lines

CoinLibsDefined += COIN_Sym
CoinLibsDefined += COIN_OsiSym

In other words, change them to

#CoinLibsDefined += COIN_Sym
#CoinLibsDefined += COIN_OsiSym

This will allow the compilation to proceed without SYMPHONY. Let me know 
if you have any other questions.

Cheers,

Ted
