I've used Cygwin in the past for a few projects, and am now trying to use it

OT and P build fine. When I go to build OSG, it fails to find the Producer
include files while building osgProducer. I found that I have to explicitly
export PRODUCER_INC_DIR and PRODUCER_LIB_DIR in order for the OSG build to
find the Producer header and include files. Is this to be expected? (The
Producer 'make install' puts things in /usr/local/Producer/include and
/usr/local/Producer/lib.)
Once that issue was resolved, core OSG and some of the plugins built.
However, the build failed in the ESRIShape plugin, failing to compile
ESRIShape.cpp at line 38 because ::read was not defined.
Any help would be appreciated.

Here are some sparse notes on building OSG under Cygwin. It builds, but
fail at runtime and I do not understand why. Also the OT example
WorkCrew has problems at runtime.
For your question, see point 5.
Hope you have more luck than me with Cygwn build.
Ciao!

1) install the following packages (the full installer ones) under
d:/gnuwin32
freetype 2.1.10
jpeg 6b-4
libpng 1.2.8
libungif 4.1.4
tiff 3.8.2-1
2) create the build file d:/buildosg.sh as below
export OSG_ROOT=/cygdrive/d/OSG_OP_OT-1.1.1-rc1
export BSD_ROOT=/cygdrive/d/gnuwin32
export OPENTHREADS_INC_DIR=$OSG_ROOT/OpenThreads/include
export OPENTHREADS_LIB_DIR=$OSG_ROOT/OpenThreads/lib/CYGWIN32
export PRODUCER_INC_DIR=$OSG_ROOT/Producer/include
export PRODUCER_LIB_DIR=$OSG_ROOT/Producer/lib/CYGWIN32
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/CYGWIN32
make $*
3) build OpenThreads
Seems you need to copy uname.exe from cygwin into this directory to have
$(OS) correctly initialized.
in pthreads_src/GNUMakefile
remove the unneeded line 31: LIBS += -lpthread
cd OpenThreads
make
4) build Producer
cd ../Producer
d:/buildosg.sh
5) Edited $OSG_ROOT\OpenSceneGraph\src\osgPlugins\ESRIShape\ESRIShape.cpp
#if defined(_MSC_VER) || defined(__MINGW32__) || defined(WIN32)
#include <io.h>
extern "C" int read(int, void *, unsigned int);
#endif
6) Under the installed freetype
edit bin/freetype-config
verify that line 12 read as the following (no D:/gnuwin32.... it
confound dependency tracking)
prefix=/cygdrive/d/gnuwin32/freetype
around line 144 edit the line to read
libs="-L$libdir -lfreetype -lz -Wl,-s -liberty -lintl -liconv
-lwsock32 -lole32 -luuid -lmsvcp60 "
4) For the jpeg plugin
edit $OSG_ROOT\OpenSceneGraph\src\osgPlugins\jpeg\GNUMakefile and change
JPEG_LIBS to JPEG_LIB
(the former for some reason is not overriden by the script definition)
5) For the gif plugin
edit GNUmakefile
ifeq ($(OS),HP-UX)
INC += $(GIF_INCLUDE)
else
INC += $(GIF_INCLUDE)
LINKARGS += -L$(GIF_LIB)
endif
6) For the tiff plugin
edit GNUMakefile
ifeq ($(OS),HP-UX)
INC += $(TIFF_INCLUDE)
else
INC += $(TIFF_INCLUDE)
#LDFLAGS += -L$(TIFF_LIBS)
LINKARGS += -L$(TIFF_LIBS) $(JPEG_LIB)
endif
7) For the png plugin
edit GNUMakefile
ifneq ($(OS),HP-UX)
INC += $(PNG_INCLUDE)
LINKARGS += -L$(PNG_LIB)
else
INC += $(PNG_INCLUDE)
endif
8) build OpenSceneGraph
cd OpenSceneGraph
d:/buildosg.sh
I had some "modification time is in the future" warning, so I repeated
the build procedure twice
x) to build the Producer examples define two new variables (OSG_INC_DIR
and OSG_LIB_DIR) and modify the
GNUMakefile for Trackball
LIBS = \
-L$(OSG_LIB_DIR) -losgProducer -losgDB -losgGA -losgText -losgUtil
-losg \
-lProducer -lOpenThreads
INC += -I$(OSG_INC_DIR)
