This appendix describes the possible defines when compiling programs using Free Pascal. A brief explanation of the define, and when it is used is also given.
Possible defines when compiling using FPC
Define
description
FPC_LINK_DYNAMIC
Defined when the output will be linked dynamically.
This is defined when using the -XD compiler switch.
FPC_LINK_STATIC
Defined when the output will be linked statically.
This is the default mode.
FPC_LINK_SMART
Defined when the output will be smartlinked.
This is defined when using the -XX compiler switch.
FPC_PROFILE
Defined when profiling code is added to program.
This is defined when using the -pg compiler switch.
FPC_CROSSCOMPILING
Defined when the target OS/CPU
is different from the source OS/CPU.
FPC
Always defined for Free Pascal.
VER2
