11\twocolitem{\tt{WXTRACE}}{(Debug build only.)
12This variable can be set to a comma-separated list of trace masks used in
13\helpref{wxLogTrace}{wxlogtrace} calls;
14\helpref{wxLog::AddTraceMask}{wxlogaddtracemask} is called for every mask
15in the list during wxWidgets initialization.}
16
17\twocolitem{\tt{WXPREFIX}}{(Unix only.)
18Overrides installation prefix. Normally, the prefix
19is hard-coded and is the same as the value passed to {\tt configure} via
20the {\tt --prefix} switch when compiling the library (typically
21{\tt /usr/local} or {\tt /usr}). You can set WXPREFIX if you are for example
22distributing a binary version of an application and you don't know in advance
23where it will be installed.}
24
25\twocolitem{\tt{WXMODE}}{(wxMGL only.)
26Sets MGL video mode. The value must be in form
27{\it width}x{\it height}-{\it depth}. The default is {\tt 640x480-16}.}
28
29\twocolitem{\tt{WXSTDERR}}{(wxMGL only.)
30Redirects stderr output to a file.}
