Hello again,

The problem occurs executing line 106 of BCP_message_single.cpp:

_tm_prob->packer->user_class = _tm_prob->user;

Best regards,

Hello,

I’m trying to put bcp to work but I’m having a problem.  I’m following the
bac example but it seems I’m missing something.

I started a blank project and did the following steps:

1. Derived classes from USER_initialize, BCP_tm_user and BCP_lp_user;
2. Overridden tm_init and lp_init in USER_initialize derived class to return
pointers to the other derived classes;
3. Called bcp_main(
) and passed a pointer to an instance of USER_initialize
derived class.

The code compiles ok. When running, tm_init() is executed and after that a
segmentation fault occurs.

Am I forgetting something? I did not create any columns or rows in the
problem. I’m just putting the code to work in an empty problem. Do you think
maybe this is the reason? Do I need to set up a problem?

I’m using version 1.2.1 of bcp.

Thanks in advance,
Antonio Duarte
