Re: [osg-users] Vec3d -> Vec3 bug under Linux ?
Hi, Robert you were right (what as surprise ;-) ) A "\ " at the end of a line was making a line being commented, but the IDE do not show it as commented... (each compiler do not consider the same syntax) Sorry for the inconvenience.

Hi Vincent, I can't work out exactly what to "bug" is in your instance, from the contents of your email it sounds like windows and linux compilers are evaluating the conversion of types in a different order and getting different results, or that their is a compiler bug. The fact that adding an explicit Vec3d() into your code suggests to me that it's not likely to be an OSG issue, rather a compile one. Robert.

[osg-users] Vec3d -> Vec3 bug under Linux ?
Hi all, I was thinking about posting in osg submission, but I don't have nothing to submit. I just had a little bug, solved now, but I thing this can be an interessting point for OSG to notice. To make a special geometry, I did a function returning a new vertex Array. In the code, all was based on Vec3d, including the return data (osg::ref_ptr ) Under windows, no problem for nothing. Under Linux, 2 of the 9 Vec3d of the array were wrong, and not constant (sometinme a wrong value, sometimes an other wrong value). to solve the problem, I just use vertices->push_back(osg::Vec3(ptA + decal - x*2.0 + z*1.5 + x*0.5 ))) instead of vertices->push_back(ptA + decal - x*2.0 + z*1.5 - x*0.5) and now all is good. Is there any unsafe conversion from Vec3d to vec3 ? I solve the problem for my application, but maybe someone have any explanation ... or maybe a bug is here... don't know..
