What do do, depends on how you got into the error.
Did you update FPC?
Did you install a 2nd newer version of fpc in parallel to the 1st fpc?
Do you have several fpc versions and copied the installation to a
Same for Lazarus.
Did you install a new Lazarus snapshot, that contains a newer fpc version?
Did you install it to a new location, in parallel to the old one?
Some config file has the wrong settings now.
Check what fpc compiler lazarus is using.
Check which fpc.cfg file this compiler uses, if it is started from
inside Lazarus, or from within the makefile if you use make. (start fpc
with -va / lots of output / search for fpc.cfg)
Check that all -Fu and other paths in this fpc.cfg file point to
directories that where installed with this version of fpc.
Note, that if you change your fpc.exe, you must also have a complete new
set of ppu files for fpc (rtl)
Check all directories in Lazarus. All -Fu settings, if you use any in
building the IDE.
If you are not sure, find your laz-config dir, back-up it,and empty it.
or "user and settings" on older windows
clean out all *.ppu and *.o files in your lazarus directory, and in the
directory of any package you installed and use in this lazarus installation.
If you use more than one installation in parallel be aware there are
many pitfalls: step1 inform yourself about --primary-config-path
