add_package_user fails when moving lfs-7.0-rc1 from new to old pc

hello

I have just compiled the 7.0-rc1 release on my fast computer. I added package users and DESTDIR-style package management using my own package manager. I'm also using bsd-init scripts.

LFS runs well on my fast computer trough chroot. So I decided to copy LFS to my old computer. That one boots to.

When I try to add a package user on my old computer, i get the following error:

Code:

root@jelle_pentium2 ~ # addpkguser htop htop

/usr/sbin/add_package_user: line 99: 1024 Illegal instruction    expr ${minuid} + 1 2> /dev/null 1>&2

/usr/sbin/add_package_user: line 100: 1025 Illegal instruction    expr ${minuid} + 1 2> /dev/null 1>&2

/usr/sbin/add_package_user: line 101: 1026 Illegal instruction    expr ${minuid} + 1 2> /dev/null 1>&2

/usr/sbin/add_package_user: line 102: 1027 Illegal instruction    expr ${minuid} + 1 2> /dev/null 1>&2

Error: Illegal numeric value!

root@jelle_pentium2 ~ #

note: addpkguser is just the install_package from the package users hint.

I compiled everything on a box running slackware-13.37

Code:

jelle@jelle-desktop ~ $ uname -a

Linux jelle-desktop 2.6.37.6-smp #2 SMP Sat Apr 9 23:39:07 CDT 2011 i686 AMD Phenom(tm) II X3 720 Processor AuthenticAMD GNU/Linux

jelle@jelle-desktop ~ $

the other box

Code:

root@jelle_pentium2 ~ # uname -a

Linux jelle-pentium2 3.0.4 #1 SMP Sun Sep 4 05:41:24 CEST 2011 i686 i686 i386 GNU/Linux

root@jelle_pentium2 ~ #

I hope anyone can help me finding out why this script crashes on my old computer, but works on the other

Try

Quote:

view +99 /usr/sbin/add_package_user

see what command exactly is failing.

the script fails at the command

Code:

expr ${minuid} + 1 2> /dev/null 1>&2

I tested expr some more and this is the result:
phenom

Code:

root@jelle-desktop / # expr 10000 + 1

10001

root@jelle-desktop / # expr 25 - 3

22

root@jelle-desktop / # expr 25 * 3

expr: syntax error

pentium

Code:

root@jelle-pentium2 / # expr 10000 + 1

Illegal instruction

root@jelle-pentium2 / # expr 25 * 3

expr: syntax error

root@jelle-pentium2 / # expr 25 - 3

Illegal instruction

The last command on my phenom should be legal according to the man page. Does this mean expr is wrong there too?

Also, I assumed that my pentium and my phenom use the same 32-bit instruction set (i686). Am I wrong in this?

That might happen if $minuid is not a number.

I copied expr from slackware to my lfs system and everything works again. currently compiling gmp and coreutils again. I hope this solves the problem, because compiling is slow without -j6.

recompiling gmp and coreutils solved the problem

Kind of off topic, but if you want to use '*' with 'expr' you must escape it first:

Code:

# expr 25 \* 3
