bug#55389: 28.1; vhdl-generate-makefile fails if there is not VHDL project

[Cyril Arnould]

When visiting any VHDL file, trying to execute vhdl-generate-makefile

(C-c M-k) will fail if vhdl-project is nil. The resulting error message

and backtrace are as follows:

 

vhdl-generate-makefile-1: Symbol’s value as variable is void: rule-alist

 

Debugger entered--Lisp error: (void-variable rule-alist)

  vhdl-aput(rule-alist "counter.vhd" (("counter") nil))

  vhdl-generate-makefile-1()

  vhdl-generate-makefile()

  funcall-interactively(vhdl-generate-makefile)

  command-execute(vhdl-generate-makefile)

 

I suspect this might be due to changes when lexical-binding was enabled,

I went back to commit d365c947b53a2a1e4b43ab65922ebfeca23943d1 where it's

working. Note that I've never used this feature before so I don't know

exactly how it's supposed to behave, I wanted to try it out. The

makefile I get from the older vhdl-mode.el does seem to make sense though, I’ve

attached it for reference.
