Rebuilding the shared-library file
If you use custom drivers or custom-conversion functions, you must rebuild the ipldd11a.SOLIBSUFFIX shared-library file with your custom-code files. (SOLIBSUFFIX is the shared-library suffix for your operating system.)
About this task
To build the shared-library file:
Procedure
-
Use the following code as a template to prepare a makefile.
You can copy a template for the makefile from the $INFORMIXDIR/incl/hpl directory.
######################################################## # Makefile for building onpload shared library # LD = ld # link flag for building dynamic library, may be different # for your platform, see the man page for ld, the link # editor. LDSOFLAGS = -G # where to find plcstdrv.h INCL = $INFORMIXDIR/incl/hpl # SOLIBSUFFIX is the shared library suffix for your # platform. For Solaris it is "so" SOLIBSUFFIX = so PLCDLIBSO = ipldd11a.$(SOLIBSUFFIX) .c.o: $(CC) $(CFLAGS) -I$(INCL) -c $< # # plcstdrv.c contains the custom driver table, required # plcstcnv.c contains the custom function table, required # your_custom_driver.c contains your custom driver #routines, optional # your_custom_conversion.c contains your custom #conversion functions, optional # SOOBJS = plcsrdrv.o plcsrcnv.o your_custom_driver.o your_custom_function.o solib: $(SOOBJS) $(LD) -o $(PLCDLIBSO) $(LDSOFLAGS) $(SOOBJS) ################ end of makefile ######################
-
Include the following files in the makefile.
File Description plcstdrv.c Prepares the custom driver tables. plcstcnv.c Prepares the custom-conversion function tables. your_custom_driver.c Contains your user-specific driver functions your_custom_functions.c Contains your user-specific conversion functions Custom-conversion functions describes the plcstcnv.c and the your_custom_functions.c files.
-
Run make by using the makefile.
The makefile builds the shared-library file ipldd11a.SOLIBSUFFIX, where SOLIBSUFFIX is the shared-library suffix for your operating system.
The HPL uses the same library for both custom-conversion functions and custom drivers, so when you rebuild the library, you must also link the custom-conversion code.
-
Install the shared library in the appropriate path for
your operating system.
For example, on Solaris you must install the shared library in the $INFORMIXDIR/lib directory, or in the directory specified by the HPLDYNAMICLIB configuration variable in the plconfig file. You can move ipldd11a.SOLIBSUFFIX into the shared-library directory, or you can use a link. For administrative purposes, a link might be clearer.
- Set the owner and group of the shared-library files to informix. Set the permission bits to 0755 (octal).
