Editing Installing Xilinx ISE (section)

== Step 2: Running xsetup ==

By default the installer script (called "xsetup") will have read and write privileges but not execute privileges. You can verify this by running <code>ls -l</code> on the file itself:

<code> ls -l /tmp/Xilinx_ISE_DS_Lin_14.7_1015_1/xsetup </code>

which will show

<code> -rw-rw-r--. 1 USERNAME USERNAME 1232147282 DATE /tmp/Xilinx_ISE_DS_Lin_14.7_1015_1/xsetup </code>

the <code>-rw-rw-r--.</code> indicates that there are read and write privileges for the user and the group and read privileges for all other users.

We will use the "chmod" command to change this file permission to be executable. We use "+x" to indicate to add executable permissions. 

<code> chmod +x /tmp/Xilinx_ISE_DS_Lin_14.7_1015_1/xsetup </code>

The output of this command is (may not show output on all platforms by default, you can check using -v before +x in the chmod command)

<code> mode of 'xsetup' changed from 0664 (rw-rw-r--) to 0755 (rwxr-xr-x) </code>

which indicates that the file has been given execute access.

Now to run the installer you can type in the command line (run the installer '''as the ROOT user to create directories'''):

<code>sudo ./tmp/Xilinx_ISE_DS_Lin_14.7_1015_1/xsetup </code>

If you get the error "could not create destination path /opt/xilinx/13.4/ise_ds" or similar upon installation, you forgot to run the installer as the root user. Exit out of it and try again. Remember to use sudo or run su root before running the command to switch to the root user for now (so you won't have to reenter your password if you get other errors.

If you get the error "error while loading shared libraries: libncurses.so.5", see [[#Arch Linux Libncurses error]] and apply the fix, then continue on with the installation.
