[Coin-discuss] Making Bcp - Solaris

[Tommy Thomadsen]

Thank you for the answer!

g++ 2.95.2 is the default compiler on the sun machine I am using but
2.95.3 and 3.0.4 are also available. Using the two last mentioned I get
various linking and "include files not found" errors not due to coin.
Anyway I was hoping to be able to use the default compiler but I guess I
cannot avoid fighting the above mentioned errors.

I did manage to compile files using 2.95.3 but I cannot link. I think it
has something to do with static/dynamic linking. I get the error shown
below. Does coin require libstdc++.so? It exists on the linux machine I
managed to compile on, but it is not on the sun machine. (I am guessing
here..)
