Problem with recompiling Xilinx Libraries in ModelSim

[BasePointer]

modelsim, cd $, modelsim.ini

I have just downloaded ModelSim 5.8d. I gave an error message "Permission denied" when I tried command below. How can I prevent this ?

ModelSim> compxlib -s mti_se -f all -l all -o .
# Release 6.2i - compxlib
#
# XILINX = 'C:\_Elkn\Xilinx'
#
# SIMULATOR = MODELSIM SE/EE
#
#
# Source Tools => [using PATH env]
#
# Initializing Logical Mapping ( => 'C:\_Elkn\FPGAdv62PS\Modeltech\win32' )
#

modelsim xilinx libraries

Are you logged in as Administrator? If not, are the permissions on that directory *and* the root of C: ok for your login?. If there is an existing modelsim.ini in that directory, is it Read Only?

I take it you are running compxlib from a console where you have CD'd to the root Xilinx directory?. Oh - also check if there is an existing compxlib.log which is Read Only.

Yes, common problem. Change your modelsim.ini from read-only to writeable. I also keep a backup copy, just in case.

Yes I changed the modelsim.ini to writeable, it works now.

Thnks for your responses.
