add fdisk --> compilation error!

[Altera_Forum]

Hi all, 

 I'm new to the uClinux, I try to implement usb device (isp1761 Usb controller) I want to create and partition a local disk (8 MB) to emulate a mass storage (diskemu). So I add fdisk in uClinux configuration.  BusyBox ---> Linux System Utilities ---> [*] fdisk  But the compilation doesn't correctly! I don't know how to correct this error!   Here is the error message when compiling :   ....  LD util-linux/built-in.o  CC util-linux/dmesg.o  CC util-linux/fdisk.o  CC util-linux/mount.o  AR util-linux/lib.a  LINK busybox_unstripped busybox_unstripped.elf2flt(.text.read_line+0x8): In function `read_line': util-linux/fdisk.c:335: Unable to reach ptr_to_globals (at 0x0003d420) from the global pointer (at 0x00045d60) because the offset (-35136) is out of the allowed range, -32678 to 32767.  collect2: ld returned 1 exit status make[3]: *** [busybox_unstripped] Erreur 1 make[3]: Leaving directory « /uClinux-dist/user/busybox » make[2]: *** [busybox] Erreur 2 make[2]: Leaving directory « /uClinux-dist/user » make[1]: *** [all] Erreur 2 make[1]: Leaving directory « /uClinux-dist/user » make: *** [subdirs] Erreur 1    When I compile without fdisk the kernel is compiled correctly (Kernel : 2.6.23-uc)  Thanks for your help. Regards,

Hi all, 

 Here are some details about my problem (selection of "fdisk" in menuconfig)  In compiling uClinux by running Cmd: make NON_SMP_BUILD=1  Here is the error obtained:  fdisk.elf2flt(.text+0x4f64): In function `xbsd_readlabel':/uClinux-dist/user/fdisk/fdiskbsdlabel.c:732: undefined reference to `bcopy' fdisk.elf2flt(.text+0x5560): In function `bselect':/uClinux-dist/user/fdisk/fdiskbsdlabel.c:534: undefined reference to `bcopy' fdisk.elf2flt(.text+0x556c):/uClinux-dist/user/fdisk/fdiskbsdlabel.c:537: undefined reference to `bzero' fdisk.elf2flt(.text+0x55d4):/uClinux-dist/user/fdisk/fdiskbsdlabel.c:552: undefined reference to `bcopy' fdisk.elf2flt(.text+0x58cc):/uClinux-dist/user/fdisk/fdiskbsdlabel.c:767: undefined reference to `bcopy' fdisk.elf2flt(.text+0x5a6c):/uClinux-dist/user/fdisk/fdiskbsdlabel.c:657: undefined reference to `bzero' collect2: ld returned 1 exit status make[3]: *** [fdisk] Erreur 1 make[3]: Leaving directory « /uClinux-dist/user/fdisk » make[2]: *** [fdisk] Erreur 2 make[2]: Leaving directory « /uClinux-dist/user » make[1]: *** [all] Erreur 2 make[1]: Leaving directory « /uClinux-dist/user » make: *** [subdirs] Erreur 1  Are there other features to enable (or not) when using fdisk? Someone he knows why I have this error?  thanks!

I once saw the bcopy() problem with some other Busyboc appltet some time ago. 

 IIRC, bcopy is an old style function that is depreciated now and needs to be replaced by something else (supposedly memcpy() - I seem to remember that the parameter order is different, bzero supposedly is replaced by memset).  Moreover the French error message suggests that you don't use the original toolchain as described in the NIOSWiki. This is not supported by this community.  I suggest following closely http://www.nioswiki.com/operatingsystems/uclinux (http://www.nioswiki.com/operatingsystems/uclinux) and http://www.nioswiki.com/installnios2linux (http://www.nioswiki.com/installnios2linux) before trying to solve any errors on your own.  -Michael

Thank you Mschnell for your reply, 

 I have successfully compiled after updating the busybox.  For have fdisk in sbin directory I add it in busybox --> Linux system utilities and not in Filesystemt applications.  Thanks,
