Environment Variables

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

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.
WXPREFIX (Unix only.) Overrides installation prefix. Normally, the prefix is hard-coded and is the same as the value passed to configure via the --prefix switch when compiling the library (typically /usr/local or /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.
WXWEBREQUEST_BACKEND This variable can be set to override the choice of the default backend used by wxWebRequest, see wxWebSession::New(). Most common use is to set it to "CURL" to force using libcurl-based implementation under MSW or macOS platforms where the native implementation would be chosen by default.
