You are welcome. It's mostly based on self-interest: I use scilab regularly (mostly on the command line though) on openSUSE Tumbleweed. > this NoClassDefFoundError usually comes from a mis- > compilation check the jar content and be sure to load it correctly. I think the jar content looks ok. I think it's some incompatibility between jdk 8 and 9 that prevents the classpath from being correctly used. The same binary works with jdk 8 (even though it is compiled against jdk 9) once the jre paths in the scilab script are appropriately adapted; but it doesn't with jdk 9. > About the patches, I just > started to review them and will push them on the 6.0 branch after > fixing the build on my machine; Many thanks. It will be great if these patches are upstreamed; it would certainly reduce my work (I maintain Scilab packages for openSUSE) during version upgrades.
