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

# CVS_ID: $Id$
#

# The MINGW32 and MINGW32VERSION variables are preconfigured for
# MinGW gcc version 3.x and must both be changed for any version
# earlier than 3.0 or for cygwin. Editing this file is one way to
# change them. An easier way, at least with GNU make, is to override
# them on the command line, e.g.
#   make MINGW32=0 MINGW32VERSION=2.8 -f makefile.g95

# If using Mingw32 (any version), set this to 1.
# If using Cygwin (any version), set this to 0.
#
# This agrees with the instructions given in docs/msw/install.txt .
# Earlier versions of this makefile suggested setting MINGW32=1 for
# recent versions of cygwin, but that would give the wrong dll entry
# point in src/msw/makefile.g95 .
#
# With cygwin, there are still some problems compiling wxWindows
# this way; './configure && make' may work better.
#

# set MIN_SUFFIX to nothing if you use only MinGW compiler, set it to
# something MinGW-specific if you want to build wxWindows with more than one
# compiler

# which version you have. But it cannot distinguish between
# 2.95.2-1 and earlier suffix versions of 2.95 . In that case,
# inspect the dates of bin/gcc.exe and bin/ld.exe ; if they
# are at least
#   2000-01-21 for gcc.exe and
#   2000-02-04 for ld.exe
# then use '2.95-late'.
#
# gcc 2.8.x and earlier require struct-return workaround
#MINGW32VERSION=2.8
#
# gcc 2.95.2 and earlier requires special thunk option
#MINGW32VERSION=2.9-early
#
# mingw gcc-2.95.2-1 supports '-shared'
# windres provided with gcc-2.95.2-1 supports temp file option
#MINGW32VERSION=2.95-late
