When building, say, glibc 2.31 using a compiler that's itself linked
|
||
|
|
against 2.33, linking fails with:
|
||
|
|
|
||
|

This is unsurprising given that libstdc++.so here is linked against 2.33,
|
||
|
|
whereas libc.so.6 here is 2.31.
|
||
|
|
|
||
|
|
This patch works around it by not building the offending program.
