# [description]
|
|
# Helper script for checking versions in the dynamic symbol table.
|
|
# This script checks that LightGBM library is linked to the appropriate symbol versions.
|
|
# Linking to newer symbol versions at compile time is problematic because it could result
|
|
# in built artifacts being unusable on older platforms.
|
|
#
|
|
# Version history for these symbols can be found at the following:
|
|
# * GLIBC: https://sourceware.org/glibc/wiki/Glibc%20Timeline
|
|
# * GLIBCXX: https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html
|
|
# * OMP/GOMP: https://github.com/gcc-mirror/gcc/blob/master/libgomp/libgomp.map
|
|
#
|
|
# [usage]
|
|
# check-dynamic-dependencies.sh <PATH>
|
|
#
|
|
# PATH: Path to the file.
|
|
# Path to the file with the dynamic symbol table entries of the file
|
|
# (result of `objdump -T` command).
