 @page envvars_overview Environment variables

 This section describes all environment variables that affect execution of
 wxWidgets programs.





 @c WXTRACE




 (Debug build only.)
 This variable can be set to a comma-separated list of trace masks used in
 #wxLogTrace calls;
 wxLog::AddTraceMask is called for every mask
 in the list during wxWidgets initialization.





 @c WXPREFIX




 (Unix only.)
 Overrides installation prefix. Normally, the prefix
 is hard-coded and is the same as the value passed to @c configure via
 the @c --prefix switch when compiling the library (typically
 @c /usr/local or @c /usr). You can set WXPREFIX if you are for example
 distributing a binary version of an application and you don't know in advance
 where it will be installed.





 @c WXMODE




 (wxMGL only.)
 Sets MGL video mode. The value must be in form
 @e widthx@e height-@e depth. The default is @c 640x480-16.





 @c WXSTDERR




 (wxMGL only.)
 Redirects stderr output to a file.
