Subj.
On my ipad I was download tar from ruby-Lang.org, then untar it. & when I try to ./configure it I receive this error:

./configure: line 426: expr: command not found
./configure.lineno: line 426: expr: command not found
./configure.lineno: line 426: expr: command not found
....
....
....
What's mean this error? I google it but not found anything.

Do you have coreutils installed? I believe expr is included in that.

Thanks! This is help me.
But now I need to install gcc. And when I try to install gcc from cydia it depends from libgcc. But this library is absent in Cydia & googling did't get me solution about install gcc. (

Ok, I installed fakegcc & gcc from this link http://code.google.com/p/iphone-gcc-full/
On step 3 when I try to install headers-lib, I receive this error:

Code: [Select]

dpkg --install headers-libs.deb                 
(Reading database ... 4838 files and directories currently installed.)
Unpacking gcc.all (from headers-libs.deb) ...

You'll need to force it with the --force parameters, read the man page. They have there package built wrong.
