| 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:

| 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
