NonStop Server for Java 4.2 Programmer's Reference

Specifying Tasks Provided by the Makefile (TNS/R Only)

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_jdk1422.

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.

make baseversion

Relinks a new java file without any custom libraries or optional libraries. The new java

executable file is not SQL compiled. This rule produces a java executable that matches what is

released on the product CD.

make javasqlcomp

SQL compiles the java executable if the NonStop SQL/MP product is installed on the system.

make clean

Removes temporary files created during the make process. Temporary files are always removed at
