Nios2 g++ compile error: unexpected reloc type R_NIOS2_UJMP

[Altera_Forum]

Hi everyone. 

 I'm trying to compile an open source project and run it on a Nios2 soft-core processor running uClinux.   The project contains round 50 files so there is a lot of compiling. So I compile all the files individually using Alteras Nios2 gcc/g++ compiler together with the -c option that produces object files.   So far so good, but when I try to link the all the files together into a single file I get this strange error message:    --- Quote Start ---   Err: unexpected reloc type R_NIOS2_CJMP(19) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_CJMP(19) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_CJMP(19) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_UJMP(18) Err: unexpected reloc type R_NIOS2_CJMP(19) Err: unexpected reloc type R_NIOS2_CJMP(19) 18 bad relocs collect2: ld returned 1 exit status   --- Quote End ---    As far as I understand it, uClinux can't handle ELF files. So after I have compiled all the sources files individually, I need to use the argument -Wl,-elf2flt[/B][/B] in the link procedure in order to convert my final file from ELF to FLT format. I can link the program without errors if I neglect the -Wl,-elf2flt [/B][/B]option but with it I get the error messages above.  There isn't really much to find on google about this matter unfortunately. The only relevant page I found is from Alteras forum but that thread went cold four years ago. Here is the link nevertheless: http://www.alteraforum.com/forum/showthread.php?t=20134&highlight=r_nios2_ujmp   Is there anyone that knows what can be wrong? If you need any files or information don't hesitate to ask.    Thank you in advance, Erik
