Summary0037250: Bootstrap fails on Linux for m68k with assembler error "Error: cannot create floating-point number"
DescriptionTrying to bootstrap FPC for Linux for m68k on Debian unstable with the binaries downloaded from [1] fails with:

[ 65%] Skipped package morphunits which has been disabled for target m68k-linux
Start compiling package numlib for target m68k-linux.

Console output:

spe.pas(1793) Fatal: There were 2 errors compiling module, stopping

The installer encountered the following error:
Compilation of "BuildUnit_numlib.pp" failed
make[2]: *** [Makefile:2838: smart] Error 1
make[2]: Leaving directory '/tmp/fpc/fpc-3.2.0~rc1+dfsg/fpcsrc/packages'
make[1]: *** [Makefile:2773: packages_smart] Error 2
make[1]: Leaving directory '/tmp/fpc/fpc-3.2.0~rc1+dfsg/fpcsrc'

I'm performing a fresh bootstrap since the build with 3.0.4 fails as well, but with a different error message [2].

A hotfix patch would be nice that can be included in the Debian package for version 3.2.0.

Steps To ReproducePerform native build on qemu-68k running Debian unstable with the binaries from [1].

Sorry Adrian,
This is because I forgot to mention that I had to add
export FPCCPUOPT="-O-"
as that are remaining optimizer bugs which
prevent successful compilation of the whole Free Pascal tree
fro m68k-linux target natively.

Could you please try to disable optimization inside
for m68k and test again?

Thanks in advance,
