open-inventor's Introduction

Open Inventor

Open Inventor is an object oriented scene graph library implemented in C++ layered on top of OpenGL. It was originally developed by SGI.

This Repository

The aim of this repository is to integrate patches applied by various Linux distributions and to apply build fixes for macOS. It is based on an import of SGI's CVS repository at :pserver:[email protected]:/cvs.

Currently, patches from Fedora and Debian are included. It also includes bug fixes, most notably for font rendering on 64 bit Linux platforms. A CMake build system has been added. It can be used instead of the traditional Makefiles. The precompiled font library libFL_i386.a and unused RPM .spec files have been removed.

Building and Installation

You can build with CMake like this:

git clone https://github.com/aumuell/open-inventor
mkdir open-inventor-build
cd open-inventor-build
cmake -DCMAKE_INSTALL_PREFIX=/opt/inventor ../open-inventor
make -j10
make install

The last step is optional, as all the programs that do not try to read from hard-coded paths also work from the build directory.

The included README.FIRST has instructions on how to use the original make build system.

For building on macOS, there is a Homebrew formula based on this repository.

More Information

Refer to SGI's Open Inventor page (archive link) for more information.

`libNurbs.c++:83:0: patch.c++: In member function ‘void _SoNurbsPatchspec::singleStep()’: patch.c++:458:58: error: call of overloaded ‘abs(REAL&)’`

On Ubuntu 18.04 I found that replacing abs with fabs eliminated this compilation error. Not sure if this is the correct approach or not.

Similar issue found in ccw.c++, arctess.c++, acr.c++, and simplemath.h.

Missing <Xm/Xm.h> Ubuntu 18.04

I used sudo apt-get install libmotif-dev not sure if this is the correct approach or not.

New source release?

Is there any intention to make a release of the source code? I see the last releases were in 2010 and were distro specific (fedora, debian). How about a new source code release with a distro-neutral tag like 2.1.6?

Compilation fails

Thanks for maintaining this formula.
On Macos Sierra I got the following error when I try to install open-inventor with your homebrew formula:

/usr/bin/libtool -L/usr/local/Cellar/openinventor/2.1.5-10/lib -L../libimage -L../libFL/freetype -undefined error -dynamic -all_load -L/opt/X11/lib -L../lib -L../libSoXt libInventor.a -ljpeg -limage -lFLiv -lfreetype -lGLU -lGL -lX11 -ldl -lm -L/usr/local/lib -lXm -lXt -lXi -lX11 -lGLU -lGL -liconv -ldl -lstdc++ -o libInventor.0.0.0.dylib

make[1]: *** [libInventor.0.0.0.dylib] Error 1
make: *** [install] Error 1

When I try to compile by myself your git repository I got also some errors :

Undefined symbols for architecture x86_64:
"_FT_Done_GlyphSlot", referenced from:
__flFTDeleteGlyphChar in libFLiv.a(flfreetype.o)
ld: symbol(s) not found for architecture x86_64
fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: internal link edit command failed
make[1]: *** [libInventor.0.0.0.dylib] Error 1

I seems that _FT_Done_GlyphSlot come from the freetype library but I don't know is this function is deprecated ...
If I comment this call, I got the ivview tool that I expected but with the following runtime error :

Warning: XmManager ClassInitialize: XmeTraitSet failed
Error: attempt to add non-widget child "DropSiteManager" to parent "ivview" which supports only widgets

Thanks for your help.
