ENVIRONMENT

WINEPREFIX

If set, the contents of this variable is taken as the name of the directory where Wine stores its data (the default is $HOME/.wine). This directory is also used to identify the socket which is used to communicate with the wineserver. All wine processes using the same wineserver (i.e.: same user) share certain things like registry, shared memory, and config file. By setting WINEPREFIX to different values for different wine processes, it is possible to run a number of truly independent wine processes.

WINESERVER

Specifies the path and name of the wineserver binary. If not set, Wine will try to load /usr/lib/wine/wineserver, and if this doesn't exist it will then look for a file named "wineserver" in the path and in a few other likely locations.

WINELOADER

Specifies the path and name of the wine binary to use to launch new Windows processes. If not set, Wine will try to load /usr/lib/wine/wine, and if this doesn't exist it will then look for a file named "wine" in the path and in a few other likely locations.

WINEDEBUG

Turns debugging messages on or off. The syntax of the variable is of the form [class][+|-]channel[,[class2][+|-]channel2]

class is optional and can be one of the following: err, warn, fixme, or trace. If class is not specified, all debugging messages for the specified channel are turned on. Each channel will print messages about a particular component of Wine. The following character can be either + or - to switch the specified channel on or off respectively. If there is no class part before it, a leading + can be omitted. Note that spaces are not allowed anywhere in the string.

Examples:

WINEDEBUG=warn+all

will turn on all warning messages (recommended for debugging).

WINEDEBUG=warn+dll,+heap

will turn on DLL warning messages and all heap messages.

WINEDEBUG=fixme-all,warn+cursor,+relay

will turn off all FIXME messages, turn on cursor warning messages, and turn on all relay messages (API calls).

WINEDEBUG=relay

will turn on all relay messages. For more control on including or excluding functions and dlls from the relay trace, look into the HKEY_CURRENT_USER\\Software\\Wine\\Debug registry key.

For more information on debugging messages, see the Running Wine chapter of the Wine User Guide.

WINEDLLPATH

Specifies the path(s) in which to search for builtin dlls and Winelib applications. This is a list of directories separated by ":". In addition to any directory specified in WINEDLLPATH, Wine will also look in /usr/lib/x86_64-linux-gnu/wine.

WINEDLLOVERRIDES

Defines the override type and load order of dlls used in the loading process for any dll. There are currently two types of libraries that can be loaded into a process address space: native windows dlls (native) and Wine internal dlls (builtin). The type may be abbreviated with the first letter of the type (n or b). The library may also be disabled (''). Each sequence of orders must be separated by commas.

Each dll may have its own specific load order. The load order determines which version of the dll is attempted to be loaded into the address space. If the first fails, then the next is tried and so on. Multiple libraries with the same load order can be separated with commas. It is also possible to use specify different loadorders for different libraries by separating the entries by ";".

The load order for a 16-bit dll is always defined by the load order of the 32-bit dll that contains it (which can be identified by looking at the symbolic link of the 16-bit .dll.so file). For instance if ole32.dll is configured as builtin, storage.dll will be loaded as builtin too, since the 32-bit ole32.dll contains the 16-bit storage.dll.

Examples:

WINEDLLOVERRIDES="comdlg32,shell32=n,b"

Try to load comdlg32 and shell32 as native windows dll first and try the builtin version if the native load fails.

WINEDLLOVERRIDES="comdlg32,shell32=n;c:\\foo\\bar\\baz=b"

Try to load the libraries comdlg32 and shell32 as native windows dlls. Furthermore, if an application request to load c:\foo\bar\baz.dll load the builtin library baz.

WINEDLLOVERRIDES="comdlg32=b,n;shell32=b;comctl32=n;oleaut32="

Try to load comdlg32 as builtin first and try the native version if the builtin load fails; load shell32 always as builtin and comctl32 always as native; oleaut32 will be disabled.

WINEARCH

Specifies the Windows architecture to support. It can be set either to win32 (support only 32-bit applications), or to win64 (support both 64-bit applications and 32-bit ones in WoW64 mode).
The architecture supported by a given Wine prefix is set at prefix creation time and cannot be changed afterwards. When running with an existing prefix, Wine will refuse to start if WINEARCH doesn't match the prefix architecture.

DISPLAY

Specifies the X11 display to use.

OSS sound driver configuration variables:

AUDIODEV

Set the device for audio input / output. Default /dev/dsp.

MIXERDEV

Set the device for mixer controls. Default /dev/mixer.

MIDIDEV

Set the MIDI (sequencer) device. Default /dev/sequencer.
