Message: 66161
Dear Sirs,
I take the source code example from:
http://www.xenomai.org/documentation/branches/v2.4.x/html/api/index.html
File name user_task.c
Then, I try to compile it in two ways:
1) bfin-uclinux-gcc -I/mnt/uClinux-dist-2008R1.5-RC3/staging/usr/include/ -L/mnt/uClinux-dist-2008R1.5-RC3/staging/usr/lib/ user_task.c -o user_task -l pthread -lnative
--> it works fine
2) bfin-linux-uclibc-gcc -mfdpic -D_GNU_SOURCE -D_REENTRANT -D__XENO__ -I/mnt/uClinux-dist-2008R1.5-RC3/staging/usr/include/ -L/mnt/uClinux-dist-2008R1.5-RC3/staging/usr/lib/ user_task.c -o user_task -l pthread -lnative
--> it doesn't work fine (output in attachment).
Then, I write to the forum for Xenomai but they tell me that they do use the fdpic format for all libes on blackfin.
So, please, any suggestion?
Best regards,
Daniele.

FDPIC is for Linux user space applications. it makes no sense in any other context.

as noted in the documentation, you cannot mix object file formats. that is what the output is telling you: you're attempting to link FDPIC code against a non-FDPIC library. build everything with the same toolchain.

Ok,
but I suppose that using "make menuconfig"...select Xenomai and so on I've a fdpic library.
So, if I understand, I need to recompile Xenomai library in fdpic format?

when you change file formats in the menuconfig system, you should run `make clean` in the dist to force everything to be rebuilt
