Specifying Tasks Provided by the Makefile

The Makefile defines several rules, where each rule performs a different task. A rule appears as a

command line argument to make, for example:

$ make javasqlcomp

Runs the javasqlcomp rule that SQL compiles the java executable if the

NonStop SQL/MP product is installed on the system.

The rules in the Makefile for tasks that you might want to perform are:

make

Invokes the default "install" rule that relinks a new java executable file. The Makefile

searches the directories listed in the variable CUSTLIB_DIRS for custom libraries to link in.

The JDBC drivers for NonStop SQL are linked in as follows:

If the JDBC Driver for SQL/MX is installed, this driver is linked in only if the

NonStop SQL/MX product is installed on the system.

❍

If the JDBC Driver for SQL/MP and the NonStop SQL/MP product are installed on the

system, the make rule SQL compiles the java executable.

❍

Make fails with an error if two archive libraries with the same name are found in the

directories listed in the CUSTLIB_DIRS variable. For example, the make operation fails with

an error message that indicates the presence of two libraries with the same name (h/mylib)

are present in the following situation:

CUSTLIB_DIRS is set to:

CUSTLIB_DIRS = /usr/tandem/java_public_lib_jdk142 /h/mylib

libjni.a exists in /h/mylib and in

/usr/tandem/java_public_lib_jdk142

This limitation applies whether the two archive files contain the same object code or different

code.

For .lib files, you can have two files with the same name in different directories as long as

the files do not contain the same code. All object files in an archive file are extracted from the

archive file and linked in explicitly into the java executable. Therefore, your archive file

should not contain code that is not needed, to keep the java executable from being

unnecessarily large.
