QuartusPenguin posted in http://www.alteraforum.com/forum/showthread.php?p=4181&mode=threaded#post4181 a possible solution for Quartus 7.2

Anyway in the quartus_unix.pdf found in http://altera.com/literature/manual/quartus_unix.pdf it can be read

To use the Visual MainWin software, which is required to run the Quartus II

software on Linux workstations, the Linux workstation requires the GNU

libc libraries (glibc). Table 3 lists the glibc versions required for each version

of Linux supported by the Quartus II software.

Table 3. Required glibc Version for Linux Workstations

Red Hat Linux Enterprise 3.0 glibc 2.3.2-95

Red Hat Linux Enterprise 4.0 glibc 2.3.4-2

SUSE Linux Enterprise Server 9 glibc 2.3.3-98

The GNU libc libraries are available at the Red Hat Linux website at www.redhat.com.

My question is... I have found using the package manager that these libraries are not installed in my system (Kubuntu 7.04). The only references the manager finds are glibc-doc, libdb1-compat (The Berkeley database routines [glibc 2.0/2.1 compatibility]), libg++2.8.1.3-glibc2.2 (The GNU C++ extension library - runtime version) and libstdc++2.10-glibc2.2 (The GNU stdc++ library).

I suppose i can find these libraries in www.gnu.org. Do you know the link to them? And more important, should i install those libraries? or a compatibility for them? Don't know if i can break the system if using old libraries not event offered in ubuntu official repos.
