At last I was able to build OSG without disrupting my PC environment!
After failed attempts with Cygwin and VS6 I succeeded with MINGW.
Here I want to share my "cookbook" and to point to some fixes that could
be included in 1.2-released.
My Environment is: WinXP, OSG 1.2-rc1. Remember that I have already
Cygwin installed, so change the points 3 and 4 accordingly.
Small corrections needed to OSG are in point 9. Corrections that need
some more work besides my quick and dirty workaround in
11-14, a strange linker problem in 16 and the evergreen WorkCrew crash
in 7. Feel free to add comments and corrections; after maybe I can also
update the MINGW build page on the site.
Now the real work starts...

1) Download from Sourceforge MinGW-5.0.3.exe and install binutils, gcc
and make. Select a destination directory without spaces in it
(so forget C:\Program Files)
2) Download from sourceforge MSYS-1.0.11-2004.04.30-1.exe and install
it. Again select a destination directory without spaces in it.
I have used C:/MinGW and C:/MSYS
3) Edit /etc/profile and put MinGW and MSYS bin directories in the path
before the Cygwin ones
PATH=/cygdrive/c/msys/bin:/cygdrive/c/MinGW/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:$PATH
export PATH
For Cygwin this is C:\Program Files\cygwin\etc\profile
4) From the control panel select System->Advanced->Environment Variables
and edit the Path variable (using the marvelous user
interface provided :-)). Put the bin directories in the following order:
C:\msys\bin;C:\MinGW\bin;C:\Program Files\cygwin\bin
Restart windows (im my case after changing /etc/profile, the Cygwin make
and uname were picked if no reboot)
5) Install the following packages (the full installer ones) under
d:/gnuwin32 for example
freetype 2.1.10, jpeg 6b-4, libpng 1.2.8, libungif 4.1.4, tiff
3.8.2-1, zlib-1.2.3
List and location is on
http://www.openscenegraph.org/osgwiki/pmwiki.php/Downloads/Dependencies
Copy the DLL from the various bin directories to C:/MinGW/bin
6) Edit the following script and source it in the shell used for build
OSG. It seems necessary to specify the paths as /d/blabla and
not as /cygdrive/d/blabla (as with Cygwin)
export OSG_ROOT=/d/OSG_OP_OT-1.2-rc2
export BSD_ROOT=/d/gnuwin32
export OPENTHREADS_INC_DIR=$OSG_ROOT/OpenThreads/include
export OPENTHREADS_LIB_DIR=$OSG_ROOT/OpenThreads/lib/MINGW32
export PRODUCER_INC_DIR=$OSG_ROOT/Producer/include
export PRODUCER_LIB_DIR=$OSG_ROOT/Producer/lib/MINGW32
export COMPILE_EXAMPLES=yes
export COMPILE_INTROSPECTION=no
export FREETYPE_INCLUDE=$BSD_ROOT/freetype/include
export FREETYPE_LIB=$BSD_ROOT/freetype/lib
export PATH=${PATH}:$BSD_ROOT/freetype/bin
export JPEG_INCLUDE=-I$BSD_ROOT/jpeg/include
export JPEG_LIB="-L$BSD_ROOT/jpeg/lib -ljpeg"
export GIF_INCLUDE=-I$BSD_ROOT/libungif/include
export GIF_LIB=$BSD_ROOT/libungif/lib
export TIFF_INCLUDE=-I$BSD_ROOT/tiff/include
export TIFF_LIBS=$BSD_ROOT/tiff/lib
export PNG_INCLUDE=-I$BSD_ROOT/libpng/include
export PNG_LIB=$BSD_ROOT/libpng/lib
export OSG_INC_DIR=$OSG_ROOT/OpenSceneGraph/include
export OSG_LIB_DIR=$OSG_ROOT/OpenSceneGraph/lib/MINGW32
7) cd OpenThreads; make
To test the examples: cd examples_src; make
WorkCrew again crash and burns...
8) cd ../Producer
9) Edit Make/makedefs line 424 and append -mnop-fun-dllimport to DEF
make. to build the examples cd Test; make. The compilation fail on
Trackball that needs OSG built first (see 16)
10) Under the installed freetype edit bin/freetype-config and change
line 12 to be (no D:/gnuwin32.... it confound dependency tracking)
prefix=/d/gnuwin32/freetype
And around line 144 edit the line to be:
libs="-L$libdir -lfreetype -lz -Wl,-s -liberty -lwsock32 -lole32
-luuid -lmsvcp60 "
11) For the jpeg plugin
edit $OSG_ROOT\OpenSceneGraph\src\osgPlugins\jpeg\GNUMakefile and change
JPEG_LIBS to JPEG_LIB
(the former for some reason is not overriden by the script definition)
12) For the gif plugin edit
$OSG_ROOT\OpenSceneGraph\src\osgPlugins\gif\GNUmakefile to contain
ifeq ($(OS),HP-UX)
INC += $(GIF_INCLUDE)
else
INC += $(GIF_INCLUDE)
LINKARGS += -L$(GIF_LIB)
endif
13) For the tiff plugin edit
$OSG_ROOT\OpenSceneGraph\src\osgPlugins\tiff\GNUMakefile to contain
ifeq ($(OS),HP-UX)
INC += $(TIFF_INCLUDE)
else
INC += $(TIFF_INCLUDE)
#LDFLAGS += -L$(TIFF_LIBS)
LINKARGS += -L$(TIFF_LIBS) $(JPEG_LIB)
endif
14) For the png plugin edit$
OSG_ROOT\OpenSceneGraph\src\osgPlugins\png\GNUMakefile to contain
ifneq ($(OS),HP-UX)
INC += $(PNG_INCLUDE)
LINKARGS += -L$(PNG_LIB)
else
INC += $(PNG_INCLUDE)
endif
15) cd OpenSceneGraph; make
16) to build the Producer Trackball example modify the GNUMakefile as:
LIBS = \
-L$(OSG_LIB_DIR) -losgProducer -losgDB -losgGA -losgText -losgUtil
-losg \
-lProducer -lOpenThreads
INC += -I$(OSG_INC_DIR)
But linker complains that cannot find -losgProducer. Strange.
