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.
7#
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 .
27#
28# With cygwin, there are still some problems compiling wxWindows
29# this way; './configure && make' may work better.

33# Set to your gcc version. Generally 'gcc --version' tells you
34# which version you have. But it cannot distinguish between
35# 2.95.2-1 and earlier suffix versions of 2.95 . In that case,
36# inspect the dates of bin/gcc.exe and bin/ld.exe ; if they
37# are at least
38# 2000-01-21 for gcc.exe and
39# 2000-02-04 for ld.exe
40# then use '2.95-late'.
