3 # Common makefile settings for wxWindows programs
4 # This file is included by all the other makefiles, thus changes
5 # made here take effect everywhere (except where overriden).
6 # The settings are for GnuWin32-derived compilers, i.e. Cygwin and Mingw32.

8 # Customize this file to match your own settings.

13 # The MINGW32 and MINGW32VERSION variables are preconfigured for
14 # MinGW gcc version 3.x and must both be changed for any version
15 # earlier than 3.0 or for cygwin. Editing this file is one way to
16 # change them. An easier way, at least with GNU make, is to override
17 # them on the command line, e.g.
18 # make MINGW32=0 MINGW32VERSION=2.8 -f makefile.g95
19
20 # If using Mingw32 (any version), set this to 1.
21 # If using Cygwin (any version), set this to 0.
22 #
23 # This agrees with the instructions given in docs/msw/install.txt .
24 # Earlier versions of this makefile suggested setting MINGW32=1 for
25 # recent versions of cygwin, but that would give the wrong dll entry
26 # point in src/msw/makefile.g95 .

28 # With cygwin, there are still some problems compiling wxWindows
29 # this way; './configure && make' may work better.
