Short answer: Package dependencies should work to ensure that you have the proper library versions installed. If you can install a package, satisfying all dependencies, and it doesn't work due to a library problem, then that is a bug, and should be reported. Long answer: Each shared library has a "soname", which consists of a name and a version number. For example, "libc6" is the soname for the current version of the libc standard C library. Sonames are used to distinguish between incompatable library versions. A program compiled with libc5 will not work with libc6, or vice versa. But a program compiled against any version of libc6 should work with any other version of libc6. It is possible to have multiple versions of the same library installed, as long as they have different sonames. Debian chooses to include the soname of a library in the package name, so that programs can depend on specific sonames for libraries. This arrangement allows Debian packages to emulate the semantics of the libraries themselves -- two packages with the same name should be equivilant, and packages with different hames can be co-installed. It is the responsibility of the package maintainer to make sure the library dependencies are properly reflected in the package dependencies. This way, installing the right packages so all package dependencies are taken care of automatically ensures that the library dependenceis are also met. > > Any info would be greatly appreciated. > ______________________________________________________ > Get Your Private, Free Email at http://www.hotmail.com > > > -- > Unsubscribe? mail -s unsubscribe [EMAIL PROTECTED] < /dev/null > -- Buddha Buck [EMAIL PROTECTED] "Just as the strength of the Internet is chaos, so the strength of our liberty depends upon the chaos and cacophony of the unfettered speech the First Amendment protects." -- A.L.A. v.
