Error when compile under Linux for SPARC: /usr/bin/ld: skipping incompatible .o

[IgorM]

Hi!

When I compile my program on Linux for SPARC, I've got error:
_{[root@host1 fpc]# fpc hello.pas
Free Pascal Compiler version 3.0.2 [2017/05/07] for sparc

hello.pas(5,40) Fatal: There were 1 errors compiling module, stopping

Could you please advise - what is wrong?

Thanx!

The format of .o that the compiler generates and that the linker wants don't match.

Wrong linker or compiler or wrong linker/compiler target.

Some linkers can accept multiple kinds of .o, but need parameters to switch (usually -m., which can be passed via the compiler using -k)

Hi Marcov!

Thanx!
Object-file , generated by fpc is " ELF 64-bit":
^{[root@host1 fpc]# file hello.o
hello.o: ELF 64-bit MSB relocatable, SPARC V9, relaxed memory ordering, version 1 (SYSV), not stripped}

When I sent to linker this target (elf64-sparc), the same error occur.
What target expect linker? - How verify full linker parameters generated by fpc ?
