AIX C routine compile and link options

The compile and link options for building C routines, such as stored procedures and user-defined functions, with the IBM® C for AIX® compiler are available in the bldrtn build script.

Compile and link options for bldrtn

Compile options:

xlc_r: Use the multi-threaded version of the IBM C compiler, needed as the routines can run in the same process as other routines (THREADSAFE) or in the engine itself (NOT FENCED).
$EXTRA_CFLAG: Contains "-q64" for an instance where 64-bit support is enabled; otherwise, it contains no value.
-I$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:

xlc_r: Use the multi-threaded version of the compiler as a front end for the linker.
$EXTRA_CFLAG: Contains "-q64" for an instance where 64-bit support is enabled; otherwise, it contains no value.
-qmkshrobj: Create the shared library.
-o $1: Specify the output file name.
$1.o: Specify the object file.
-ldb2: Link with the Db2 library.
-L$DB2PATH/$LIB: Specify the location of the Db2 runtime shared libraries. For example: $HOME/sqllib/$LIB. If you do not specify the -L option, the compiler assumes the following path: /usr/lib:/lib.
-bE:$1.exp: Specify an export file. The export file contains a list of the routines.

Refer to your compiler documentation for additional compiler options.
