I downloaded Thunderbird 1.0.7 in .tar.gz form and untarred it.

Apparently, there's no need to run ./configure && make. You just do ./thunderbird.

Doing that gives:

What is the problem?

well this means that a program (called from the script executed) wants to execute something in the RAM of you computer, wich isn't allowed to do so.

This can be caused by having the wrong rights on folders/binaries and such.. (e.g. only read access instead of read-write rights or wrong group/user rights)
Check that you have the right permissions for thunderbird.

also it can (not often) be caused by using a wrong version of gcc of glibc (e.g. the binary is compiled by a newer version as there is present on the system it is executed)


hope this will give you a push in solving the issue.

How about if you do it as root?

Arubin, initially, I was dismayed, because in the terminal the same error message emerged.

However, it seemed to be somewhat on the right track, because the Netscape Quality Feedback Tool thing came up.

Of course if you are running ubuntu the easiest wat to get thunderbird running is to use ubuntu's repository and the GUI tool, (is it Synaptic?) rather than installing via the tarball.
