Compiling my project in different PCs ?

[ToTo]

I want to know if it is normal to have different hex files after compiling the same project from each one in a different PCs using the same IDE Keil ? That's really strange .. And Any explication for that please ?

Both hex function as demanded wherever are compiled.

if it is the same project settings, same keil version with same underlying cross compiler in the same operating system of the PC with same processor, then I would expect that the hex files would not differ. If anything of the above differs, then different hex file is not a shocking news.

In short if exactly same cross compiler executable is used to compile your project with same settings, then the hex files must be same.

Adding to this there are also quite a few Keil configurations that will result in different hex files, such as turning on/off MicroLib, changing optimization level, processor predefines, etc...
