This is in access/transam.h.

This macro is actually defined in access/transam.h.

[Tiny Debug Issue] Undefined Reference problem encountered during compile

[이재훈]

First of all, thank you for listening to this mail.

As I mentioned in the title, I got a undefined reference in compiling time.
The reason that I wonder is that I surely add header file for the function.

In more detail,

I want to use TransactionIdEquals() function in freelist.c file.
Then, I included a header file, "access/xact.h" for the function.

However, in make command, compiler send implicit declaration of function
warning and then undefined reference at linking time.

How could I overcome this problem? :(
