26 | This might be because you set the environment variables *after* already |
---|
27 | compiling. The environment variables control C-pre-processor macros of |
---|
28 | the same name and therefore influence what code gets compiled. It is |
---|
29 | suggested to proceed with the following manual procedure to correct the |
---|
30 | current installation: |

34 | Configure the environment according to the installation making sure |

35 | to -unset- the <literal>G4WORKDIR</literal> environment variable, |
---|
36 | if set. |
---|
37 | </para></listitem> |
---|
38 | Verify and eventually set the environment variables of the |
---|
39 | visualization module [name] concerned (setenv or export both |
---|
40 | <literal>G4VIS_BUILD_[name]_DRIVER</literal> and |
---|
41 | <literal>G4VIS_USE_[name]</literal> variables according to the UNIX |
---|
42 | shell used), and then proceed as follows: |
