Subject: [PATCH] Fix linking with boost 1.75.0
|
|
|
|
Boost 1.75.0 has a bug that causes "multiple definitions" errors in the
|
|
linking stage. This was fixed in later versions by declaring some
|
|
functions as inline.
|
|
|
|
See https://github.com/boostorg/safe_numerics/issues/106 .
|
|
|
|
As a (ugly) workaround, override the function that breaks kdiff3's build
|
|
to be inline before including the boost headers (when using 1.75.0).
