[ELDK] Rebuilding busybox in ELDK 4.1 for arm platforms

[Giuseppe Modugno]

Hi all,

I want to rebuild busybox to use ash shell instead of msh shell (the 
shell compiled in busybox of SELF ramdisk).

The first strange thing.

user at ubuntu704desktop:~/eldk41arm$ arm-linux-rpm -i 
/mnt/target/SRPMS/busybox-1.3.0-1.src.rpm 
user at ubuntu704desktop:~/eldk41arm$ arm-linux-rpm -qa | grep busybox
user at ubuntu704desktop:~/eldk41arm$ arm-linux-rpm -e busyboxerror: 
package busybox is not installed
user at ubuntu704desktop:~/eldk41arm$ arm-linux-rpm -e busybox-13.0-1
error: package busybox-13.0-1 is not installed
---
It seems the package isn't added in the local database of installed 
packages. So I can't remove it. But I think it is really installed 
because:
---
user at ubuntu704desktop:~/eldk41arm$ ls ./usr/src/denx/SOURCES/
busybox-1.00-eldk-ctty.patch         busybox-1.3.0-eldk-multiple-
consoles.patch
busybox-1.3.0-eldk-config            busybox-1.3.0-eldk.patch
busybox-1.3.0-eldk-loadfont.patch    busybox-1.3.0-eldk-printf-
gettext.patch
busybox-1.3.0-eldk-logconsole.patch  busybox-1.3.0.tar.gz
busybox-1.3.0-eldk-malloc.patch
---


The second strange thing:
---
user at ubuntu704desktop:~/eldk41arm/usr/src/denx/SPECS$ grep ppc 
busybox.spec 
make  HOSTCC="/usr/bin/gcc -B/usr/bin/" ARCH=ppc oldconfig
make  HOSTCC="/usr/bin/gcc -B/usr/bin/" ARCH=ppc CC="gcc 
$RPM_OPT_FLAGS"
make  HOSTCC="/usr/bin/gcc -B/usr/bin/" ARCH=ppc CC="gcc 
$RPM_OPT_FLAGS" doc busybox.links
- bump again for double-long bug on ppc(64)
---
I think make is wrongly called with ARCH=ppc parameter, so I changed 
them in ARCH=arm.


Now the third strange thing:
---
user at ubuntu704desktop:~/eldk41arm/usr/src/denx/SPECS$ arm-linux-
rpmbuild -ba busybox.spec 
...
+ make HOSTCC=/usr/bin/gcc -B/usr/bin/ ARCH=arm CC=gcc -O2
  SPLIT   include/autoconf.h -> include/config/*
  GEN     include/bbconfigopts.h
  HOSTCC  applets/usage
  GEN     include/usage_compressed.h
  CC      applets/applets.o
  CC      applets/busybox.o
  LD      applets/built-in.o
arm-linux-ld: applets/applets.o: Relocations in generic ELF (EM: 3)

make: *** [applets] Error 2
error: Bad exit status from /home/user/eldk41arm/var/tmp/rpm-
tmp.83224 (%build)


RPM build errors:
    Bad exit status from /home/user/eldk41arm/var/tmp/rpm-tmp.83224 
(%build)
---


So I changed "make" in busybox.spec to use arm-linux-gcc and not gcc:
---
user at ubuntu704desktop:~/eldk41arm/usr/src/denx/SPECS$ grep make 
busybox.spec 
make  HOSTCC="/usr/bin/gcc -B/usr/bin/" ARCH=arm oldconfig
make  HOSTCC="/usr/bin/gcc -B/usr/bin/" ARCH=arm CC="arm-linux-gcc 
$RPM_OPT_FLAGS"
make  HOSTCC="/usr/bin/gcc -B/usr/bin/" ARCH=arm CC="arm-linux-gcc 
$RPM_OPT_FLAGS" doc busybox.links
---


And now I have the following error:
---
user at ubuntu704desktop:~/eldk41arm/usr/src/denx/SPECS$ arm-linux-
rpmbuild -ba busybox.spec 
...
  CC      networking/inetd.o

error: Bad exit status from /home/user/eldk41arm/var/tmp/rpm-
tmp.79428 (%build)


RPM build errors:
    Bad exit status from /home/user/eldk41arm/var/tmp/rpm-tmp.79428 
(%build)
---

Really if_addr.h and if_link.h aren't present in  
~/eldk41arm/arm/usr/src/linux/include/linux, but I have them in 
/usr/include/linux (Ubuntu kernel include files).


How can I solve these problems to build busybox again? After that, 
how can I modify the configuration of busybox to use ash shell?


Thanks for the help.
