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.
WXSUPPRESS_SIZER_FLAGS_CHECK | If set, disables asserts about using invalid sizer flags in the code. This can be helpful when running older programs recompiled with wxWidgets 3.1 or later, as these asserts are mostly harmless and can be safely ignored if the code works as expected.
WXLANGUAGE | This variable can be set to override OS setting of preferred languages and make wxUILocale::GetPreferredUILanguages() return the set list instead. The format is same as GNU's LANGUAGE variable: a colon-separated list of language codes.
