[SLUG] Ubuntu gcc version problem
Just upgraded. There only seems to be one version of gcc available in the repositories. apt-cache show gcc-4.2 tells me I have Version: 4.2.3-2ubuntu7 [EMAIL PROTECTED]:~$ gcc --version gcc (GCC) 4.2.4 (Ubuntu 4.2.4-1ubuntu3) [EMAIL PROTECTED]:~$ cat /proc/version Linux version 2.6.24-21-generic ([EMAIL PROTECTED]) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) When I run vmware-config.pl I get the following warning message: Your kernel was built with gcc version 4.2.3, while you are trying to use /usr/bin/gcc version 4.2.4. What version am I running? Should I care? vmware-config.pl gives dire warnings about impending crashes, although I've found two posts on the net suggesting that I can bypass the warning. Failing that, is it a reasonable workaround to restart with an older kernel? thanks, David. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
