[Coin-discuss] CBC: STATUS_ACCESS_VIOLATION

[Donald Bennett]

John,
Thank you very much for your advise.   After modifying the Makefile.solve to add GLPK references (which I had used to build COIN the first place) I successfully made "solve.exe".  To be sure, I remade CBC and unitTest as well.   As a result I was able to successfully run the MIPLIB AIR003 test case.  No other changes were required.
 
I am using gcc version 3.4.4 (cygming special).  
 
All is well and thanks to you I am back on my feet.
 
Thanks so much.
 
Don

Donald, 

I tried under CYGWIN with gcc 3.3.3 and had no problems - well I had to change all char * environ = getenv("HOME); statements as it did not like environ as a name - I will change when I reboot on Linux. 

What version of gcc are you using? 

If using Cbc and Clp it is now recommended that you do "make solve" in Cbc and then use "solve" not "cbc".

Running under CYGWIN

COIN/CLP/OSI/CGL/CBC all compile successfully.  unit tests are successful

Trying to run ./MIPLIB3/AIR03 test case.  Other MIPLIB3 test cases fail.

Updated COIN from CVS and recompiled. No change

Can anyone else reproduce fault or obtain optimal result under similar OS?

thanks
