Compiling OpenInventor(TM) on Mac OS X Tiger

By Kuratate0

First report created: June 5, 2008

(Panther-SGI Imagelib fixed version is described in 'Compliing OpenInventor on Panther (Imagelib fixed)', Leopard version is described in 'Compling OpenInventor on Leopard' page.)

Update Xcode on 10.4 Tiger

First of all, you should update your Xcode on Mac OS X 10.4 to compile OpenInventor (ver 2.4 or higher).

You can get it from Apple Developer Connection (ADC) (2008 Jun: recent version is 2.5 (Posted 30 Oct 2007), 902.9MB)

Apple Developer Connection Top page:http://developer.apple.com
ADC Tools download page:http://developer.apple.com/tools/download

Install libraries, obtaining OpenInventor tar.gz file and patch for 10.3 Panther

(Many thanks to www.memntion.com!)

First of all, the patch file in this page is based on 'ivpatch' by http://www.memention.com/ivscript.

The followings are the summary of steps by ivscript.

install fink
install openmotif3, libjpeg, freetype2, freetype2-dev using fink
obtain OpenInventor source code (inventor-2.1.5-10.src.tar.gz) from SGI (http://oss.sgi.com/projects/inventor/, click Download and download from their FTP server)
expand inventor-2.1.5-10.src.tar.gz
apply ivpatch (patch -p 0 < ivpath)
define DYLD_LIBRARY_PATH
(go to the next section for 10.4 Tiger)

Compiling on Mac OS X 10.4 Tiger

Author tested on PowerPC Macs (PowerBook G3, PowerBook G4 and PowerMac G4) and Intel Mac (MacPro), and found that they required different patches for each system. Please download ivtiger_ppc_patch for PowerPC Mac or ivtiger_intel_patch for Intel Mac.

Apply patch according to your CPU type (patch -p 0 < ivtiger_ppc_patch or ivtiger_intel_patch) (You have to apply 'ivpatch' for 10.3Panther before this!)
cd inventor, and make
(It will stop around installing /usr/man/man1 for normal users)
- For PPC Mac: sudo make will compile everythint
- For Intel Mac: even sudo make will stop at /usr/man/man1 -> just 'cd apps' and make again

You can try ivview or SceneViewer to test the new binaries: However, Intel Mac cannot read binary inventor data...

Problems, Information, etc...

Intel Mac cannot read binary OpenInventor data (could be an Endian problem?)
The default texture quality is 0.5: however, it is much better to change higher for recent graphcis systems.
Just changing default value in lib/database/include/Inventor/elements/SoTextureQualityElement.h (line 87) from 0.5 to0.9 make it easier to get better texture mapping without changing in your program or data (like the default texture output was better when you used Reality Engine).
Adding extra libraries in localrules.apple and adding library path in ivcommondefs will prevent following errors before applying the patch for Tiger.
- For PowerPC: inventor/make/localrules.apple
  >> LLDLIBS += -lXi -lXm -lXt -lX11 -lGLU -lGL -liconv -ldl -lstdc++.6 -lmx -lgcc_s.10.4 -lgcc -lSystemStubs
  
  Without each library for this patch, you will get following errors when the compiler build libInventor.dylib. (Specifying -lgcc and -lgcc_s.10.4 causes 'warning multiple definitions', but it is not so critical....)
  - without -lgcc
```
ld: Undefined symbols:
restFP
saveFP
/usr/bin/libtool: internal link edit command failed
```
  - without -lgcc_s.10.4
```
ld: Undefined symbols:
__Unwind_Resume
/usr/bin/libtool: internal link edit command failed
```
  - without -lSystemStubs
```
ld: Undefined symbols:

_sprintf@LDBLStub
_vsprintf@LDBLStub
_printf@LDBLStub
_fscanf@LDBLStub

/usr/bin/libtool: internal link edit command failed
```
- For Intel Mac: inventor/make/localrules.apple
  >> LLDLIBS += -lXi -lXm -lXt -lX11 -lGLU -lGL -liconv -ldl -lstdc++.6 -lmx -lgcc_s.10.4
  - without -lgcc_s.10.4
```
ld: Undefined symbols:
__Unwind_Resume
/usr/bin/libtool: internal link edit command failed
```
inventor/libimage/libimage.a is a library to read / write SGI Imagelib format images: the patch fixes for reading, writing and for 64bit, but only reading function is verified.
