Hi.

I have installed ghdl in Ubuntu 10.10 (using apt-get from the repository)
and used the hello_world example available in the ghdl manual. I can analyze
(-a) and elaborate (-e) successfully but when I try to run/execute (-r) it,
I get the following error:
/usr/lib/ghdl/bin/ghdl: compilation error

To elaborate my problem, I have attached the vhdl code with this e-mail and
the sequence of commands that I follow is mentioned below:

$ ghdl -a hello.vhdl
$ ghdl -e hello_world
$ ./hello_world
bash: ./hello_world: Permission denied
$ ghdl -r hello_world
/usr/lib/ghdl/bin/ghdl: compilation error

I have tried working as root too but without success. The permissions are
perfect, the execute bit is set. Everything seems to be fine, but still it
doesnt work. I have even tried reinstalling the ghdl package.

Can someone please tell me what could be the source of problem?

Thanks and Regards,
