Informix Error -4651: The p-code compiler is not contained in your path.

Cause and resolution

The p-code compiler is not contained in your path.

The source module or program cannot be compiled because the compiler cannot be executed. It should be located in the bin directory pointed to by the INFORMIXDIR environment variable; however, that directory also must be listed in the PATH environment variable before the program can be called.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-4651 fires when the p-code compiler can't be executed — per the official guidance, it should be located in the bin directory pointed to by INFORMIXDIR, but that directory also needs to be listed in the PATH environment variable before it can be invoked.

INFORMIXDIR's bin directory isn't listed in PATH, per the official guidance — the direct, only cause.

Solutions / Resolution

Add $INFORMIXDIR/bin to the PATH environment variable, per the official guidance.

Examples

Adding INFORMIXDIR/bin to PATH

$ export PATH=$INFORMIXDIR/bin:$PATH

Diagnostic Checks

Check PATH and confirm it includes $INFORMIXDIR/bin; add it if missing.

The p-code compiler can't be executed because INFORMIXDIR/bin isn't in PATH — add it.
