this looks to be the actual error:

fpcdefs.inc(288,2) Error: User defined: Cross-compiling from systems without support for an 80 bit extended floating point type to i386 is not yet supported at this time

Looks like you can't cross compile from an arm64 system to i386?

[kamischi (Karl-Michael Schindler)]

The linker warnings are annoying, but harmless. Maybe, I find the time to switch them off. The 80 bit extended floating point type problem for i386 targets is actually a known issue and there might be no other solution than to switch off building the cross-compiler for i386, by taking it out of the list of platforms.

This might be a preliminary quick fix: delete i386 in the list of build.target in the subport "${name}-cross" in the Portfile of fpc. At least the cross compilers for other cpus will be built.

This might actually all I can do from my side. The emulation of the 80 bit extended floating point type on non-i386 platforms is probably never to happen.

[kencu (Ken)]

I tried just turning off the i386 target when on arm64 like this:

    build.target    aarch64 arm avr i386 i8086 jvm m68k mips mipsel powerpc powerpc64 sparc x86_64
    switch ${build_arch} {
        x86_64 {
            build.target-delete x86_64
        }
        arm64 {
            build.target-delete aarch64
+            build.target-delete i386
        }
    }

but that didn't work due to :
