Hello,
I use gnat/alire under debian (latest version). Now suddenly I get the confusing error message below after "alr build". Anybody who could give me a hint?

It's hard to say without the source code. The linker can't find command_processing1__set_wellplate1 symbol used somewhere in kobio0.adb.

The source code is more than 20K lines :-)
Would be nice with error messages which are easier to understand.
I did return to the version before the latest changes and retyped - now it works and the Ada goddess smiles to me.
I googled "gnat undefined reference" and noticed that others also have encountered mysterious "undefined reference to...". Seems one have to be careful and frequently check when developing programmes above some size limit.
