"""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
