sci-physics/geant-4.9.1_p02 wants to be able to get an openinventor with USE=openinventor. However, on sparc we must package.use.mask this option because openinventor will not build. It will not build because its architecture file (machine.h) does not know about sparc linux (or any big-endian linux for that matter). With the following little patch, openinventor will build and install on sparc, and the demos all seem good. I do not know if everything is correct, however, because this change only matters in a couple classes (SoInput, SoOutput), and I don't know if the demos hit them. No attachment because the test patch changes only one line. =============================================== polylepis inventor # diff -u lib/database/include/machine.h- lib/database/include/machine.h --- lib/database/include/machine.h- 2008-07-16 12:54:21.000000000 +0000 +++ lib/database/include/machine.h 2008-07-16 12:54:34.000000000 +0000 @@ -106,7 +106,7 @@ * SUN/BSD machine dependent setup */ -#if sun +#if sun || sparc #define MACHINE_WORD_FORMAT DGL_BIG_ENDIAN #define MACHINE_FLOAT_FORMAT DGL_BIG_IEEE ================================================
feel free to apply this patch, thanks.
I have put the patch in the repository, so it should build now. Have fun!
Thanks, Stefaan, it builds now as expected.. I've keyworded media-libs/openinventor-2.1.5.10-r2 as ~sparc and removed the package.use.mask for openinventor on sci-physics/geant. I intend to mark openinventor stable about the 8th of September unless someone needs it sooner (the patch has been available since the 16th of July).
