## Name: xmversion.sh - a fast way to get a motif lib's version
|
||||
## Name: glibcversion.sh - Print __GLIBC__ version if gnu libc 2 is
|
||||
## found.
|
||||
##
|
||||
## Description: Print the major and minor version numbers for motif libs on
|
||||
## the system that executes the script. Could be tweaked
|
||||
## to output more info.
|
||||
##
|
||||
## More checks need to be added for more platforms.
|
||||
## Currently this script is only useful in Linux Universe
|
||||
## where there are a many versions of motif.
|
||||
## Description: This script is needed by the mozilla build system. It needs
|
||||
## to determine whether the current platform (mostly the
|
||||
## various linux "platforms") are based on the gnu libc2. This
|
||||
## information is later used in mozilla to determine whether
|
||||
## gnu libc 2 specific "features" need to be handled, such
|
||||
## as broken locales.
