$EXTRA_C_FLAGS

Contains one of the following:

-m31 on Linux for zSeries only, to build a 32-bit library;
-m32 on Linux for x86, x64 and POWER®, to build a 32-bit library;
-m64 on Linux for zSeries, POWER, x64, to build a 64-bit library; or
No value on Linux for IA64, to build a 64-bit library.

-I$DB2PATH/include

Specify the location of the DB2 include files. For example: $HOME/sqllib/include

-c

Perform compile only; no link. Compile and link are separate steps.

Link options:

gcc

Use the compiler as a front end for the linker.

$EXTRA_C_FLAGS

Contains one of the following:

-m31 on Linux for zSeries only, to build a 32-bit library;
-m32 on Linux for x86, x64 and POWER, to build a 32-bit library;
-m64 on Linux for zSeries, POWER, x64, to build a 64-bit library; or

-o $1

Specify the executable.

$1.o

Include the program object file.

utilci.o

Include the utility object file for error checking.

$EXTRA_LFLAG

-L$DB2PATH/$LIB

Specify the location of the DB2 static and shared libraries at link-time. For example, for 32-bit: $HOME/sqllib/lib32, and for 64-bit: $HOME/sqllib/lib64.
