{ to use this profile intrastructure, the epiktimer sources must be available, the official repository is currently:
|
|
|
|
https://github.com/graemeg/epiktimer.git
|
|
|
|
clone it into the same base directory fpc is checked out/cloned, i.e.
|
|
<base dir>/fpc/compiler
|
|
<base dir>/epiktimer
|
|
|
|
As the offical branch requires the use of the classes units, I recommend to
|
|
use my modified version of epiktimer which allows to disable the use of the classes unit,
|
|
this is done automatically by the compiler sources through a define. You can get my epiktimer source from
|
|
|
|
https://github.com/FPK/epiktimer.git
|
|
|
|
clone them into the same base directory fpc is checked out/cloned, i.e.
|
|
<base dir>/fpc/compiler
|
|
<base dir>/epiktimer
