It is highly recommended to check the newly built companion libraries.
|
|
Unfortunately, this is a very intensive task, and takes a loooong time.
|
|
|
|
Checking the newly built companion libraries is thus disabled by default,
|
|
but it is suggested that you check them at least once on your machine,
|
|
and if they work, disable the check on subsequent builds.
|
|
|
|
If you suspect that one (or more) of your companion libraries is the
|
|
cause for incorrectly generated code, you should answer 'Y' here.
|
|
Note however that this will take a really long time. For example,
|
|
building PPL on my machine takes roughly 1'40", while checking it takes
|
|
about 1h40'...

By default, the companion libraries will be build static. If you want to

needed (see docs/overview.txt,section "Tools wrapper").

It is highly recommended that you keep static libraries.
