Is Xojo 2015 Release 2.4 compatible with Big Sure?
No, Big Sur requires 64 bit applications.
2017r3 was the first 64 bit Mac IDE.
but i know it allows run but not build. It is true ?
You will not be able to launch Xojo 2015r2.4 on Big Sur because it is a 32bit application. You will not be able to run or build. Xojo will not open.
…and with win10 or win11 ?
