Source of Lib Flip to Compile for Linux

[RuolunWeng]

Hi,

When I try to compile KIWI(Its Server particularly) on Linux Ubuntu 20.04 64bit ARM,
"./Server" Linux version in the KIWI release is not going to execute :

-bash: ./Server: cannot execute binary file: Exec format error

So I suppose it should be recompile for my system. But when I try to compile it from KIWI git, I still got format problem from static lib Flip:

/usr/bin/ld: ../ThirdParty/flip/lib/gcc/libflip.a(flip.BackEndBinary.o): Relocations in generic ELF (EM: 62)
/usr/bin/ld: ../ThirdParty/flip/lib/gcc/libflip.a: error adding symbols: file in wrong format

And I can not find Flip sources from internet to recompile..

I post this question here and hope get some feedback...
Thx
