ghdl -r produces compilation error

[ZX_Spectrum]

I am using ghdl on Ubuntu 14.04 and vim syntastic

before I used to have no problem with the sequence:

ghdl -a my_file.vhd
ghdl -e my_file
ghdl -r my_file

but after installing syntastic (and I am not sure of this time-connection).

I cannot execute ghdl -r any more whenever I do that I get

$> ghdl:compilation error

without any further description

ls -l on my work folder shows:

-rw-------1 my_pc my_pc 412696 May 4 16:48 my_file

it seems to me that the produced binary is not even executable.

chmod +x my_file has no effect.

Could you suggest a solution. Note: I am new to Linux,vim and vhdl.

GHDL isn't a mainstream simulation (i.e. professional grade) tool are you sure it supports all the statements you are using?

Seems to me you should try something simple like some FF code https://www.asic-world.com/examples/vhdl/d_ff.html.

I can't see how VIM could do anything to your GHDL installation, perhaps it was syntastic that replaced something with a new version that GHDL is incompatible with.

You would probably be better off downloading Altera's free web tool suite and the free version of Modelsim they have. It would compile the above code without problems (I checked it both on Modelsim and Vivado, though I am using the PC version).

Unless you already have done so, I suggest you report this on the GHDL site.

And ask them nicely, to improve their really poor error messages ;-).
