unable to make install - read-only file system

Hello everyone, this is my first time to this forum, first time using knoppix and first time with linux so please understand if my question sounds stupid....

I have a partion on my hard drive for knoppix already (/mnt/hda5/). Knoppix works fine and I have downloaded some packages that I require and these are sitting on my new partition.

I am trying to install:

glib-2.6.1
atk-1.9.0
gtk+-2.6.1
pango-1.8.0

However... starting with glib... seems others require glib first...

I ./configure and all seems fine, i then make and all looks fine though when i try to make install i am returned errors:

knoppix@ttyp1[glib-2.6.1]$ make install
make install-recursive
make[1]: Entering directory `/mnt/hda5/gtk/glib-2.6.1'

What is the problem here and how do I fix it?

Thank you :)

Still have same problem though now experiencing problems with all files on hda5... says they are a Read-Only File System. What could have caused this and how can I fix it? I am unable to extract any files or anything while in this state.

Right click on desktop hda5 icon and goto actions. Then change read/write option. That should now allow you to write to the hd.
