DB2 version 8.1 fixpak 4
Redhat 8 Linux

I'm trying to compile a userexit program (db2uext2.c) and I get the following errors:

db2uext2.c: In function `ArchiveFile':
db2uext2.c:732: `offset_t' undeclared (first use in this function)
db2uext2.c:732: (Each undeclared identifier is reported only once
db2uext2.c:732: for each function it appears in.)
db2uext2.c:732: parse error before "offsetll"
db2uext2.c:804: `offsetll' undeclared (first use in this function)
db2uext2.c:804: parse error before "startingPage"

Line 732:
offset_t offsetll;

Line 804:
offsetll = (offset_t)startingPage * 4096;



Declare for offset_t in the program:

/* HP does not define llseek and offset_t */
#ifdef _INCLUDE_POSIX_SOURCE
# define llseek lseek
typedef unsigned long offset_t;
#endif



Do I comment this out? Delete it altogether?

gcc -D_INCLUDE_POSIX_SOURCE -o db2uext2 db2uext2.c
