[fpc-devel] Problem compiling ARM/linux builds with extra options

  I am currently trying to compile FPC with different options. In
particular I am trying to compile a armel build with vfp enabled.

However it fails at compiling the packages, i.e. fpmkunit due to "Trying
to use a unit which was compiled with a different FPU mode". The issue
from the make output (see below) is pretty clear, the additoinal options
passed via OPT are not passed to package making.

I guess it needs some additional new command line param that I am

On a related note, is there any documentation on the "new"
fpmake/fpmkunit system related to new options? As you may note I am
already aware of FPMAKEOPT, but there probably are a few new ones.

Command line:

make clean zipinstall -j 4 PP=ppcarm FPMAKEOPT="-T 4" OPT="-dFPC_ARMEL
-Cfvfpv2 -Cparmv7"  NOWPOCYCLE=1


make -C fpmkunit bootstrap
