[Coin-discuss] Problems running Sbb on miplib

[Mikhail Nediak]

Dear COIN community,

I am having some problems with running Sbb. Everything compiled and linked
almost fine. I have not really changed anything in the makefiles, except
that my "default" installation of Mandrake does not include readline and
stuff, so I had to comment out corresponding lines (so that
symbol READLINE is no longer defined).

I could run

sbb -unitTest

without any problems. However,

sbb -miplib

produces this output:

Testing some miplib stuff

Similar thing happens after making Sample1 and running, say

testit miplib3/p0033

Except that in this case it crashes a bit later:
...
Sbb0014I Cut generator 3 (Unknown) - 0 row cuts (0 active), 0 column cuts
- new frequency is 0
Sbb0010I After 0 nodes, 1 on tree, 1e+50 best solution, best possible

What am I doing wrong? I am running Mandrake Linux 9.0 and g++ 3.2.
The same thing happened on another computer running RedHat 7.3 and
g++ 2.96.

I will be very grateful for any suggestions.

Thanks.

Best regards,
