Subject: [PATCH 3/6] Fix libbtf 0.6.0 build
|
|
|
573668 |
|
|
|
573668 |
Libbtf 0.6.0 introduced a new version of btf_dump__new(). The new
|
|
|
573668 |
version is btf_dump__new_v0_6_0() while the old version was renamed
|
|
|
573668 |
btf_dump__new_deprecated(). btf_dump__new() is now overloaded,
|
|
|
573668 |
unfortunately the macro doesn't work on cpp, at least with LLVM 12.
|
|
|
573668 |
Let's call btf_dump__new_deprecated() explicitely when it's defined.
