help me

Hi Luca,

it looks like you don't have the ruby shared object on your system. Since you have Ruby, it's likely you have a static library (libruby.a) in /usr/local/lib for example, but KLayout won't build against that.

To solve the problem, you can either try to get a shared object (libruby.so) or build Ruby yourself and use that version.

Matthias hello thank you very much but still not solve,
I have find this library of ruby : /usr/local/lib/libruby-static.a
please note that on my system is installed working version of klayout 0.22.5 and it works fine.
I don't know anymore what to do.
bye

Matthias

Hi Luca,

you can try to link against the static ruby lib by using

build.sh -rblib /usr/local/lib/libruby-static.a

but static libraries have been deprecated in some Ruby versions and some symbols may be missing. Hence there is some chance it won't work.

If that fails, maybe there is somebody who can provide you with a fully functional Ruby installation including a libruby.so. If you have one, make sure that ruby interpreter is in the path and run build.sh. The build script will then use that installation. Another option is to build and install your own Ruby interpreter and use that one.

Basically it's hard for me to take care of every kind of Linux installation. The build script supports most free distributions out of the box. For other systems, specifically Red Hat, I have to rely on the ability of the users to solve the build issues.
