FSUM9415 Don't know how to make jvm when trying to compile CICS Java samples

Troubleshooting


Problem

When you enter "make jvm" to compile the CICS Java™ samples, you receive make error FSUM9415 Don't know how to make jvm .

Cause

Command make jvm is not being entered from the hierarchical file system (HFS) directory that contains the file Makefile.

Resolving The Problem

Do the following to ensure that you are in the correct directory prior to entering the make command:

  1. Enter cd /usr/lpp/cicsts/cicsxxx/samples/dfjcics/ from within TSO OMVS, where xxx is the release of CICS (for example "670" for CICS TS 4.2). This will change directories to the directory containing file Makefile. If you copied the directories that are shipped with CICS to your own directories, then change the directory name accordingly.

  2. Enter ls -l to display the contents of this directory.

  3. If you do not see the following files, make sure your CICS installation jobs completed successfully
    /MV20/cicsts/cics670/samples/dfjcics:>ls -l

  4. Once the correct files display, enter make jvm to compile or build the Java examples.
